South Cheshire on the Map: Our Global Hydraulics Success

Little did we know when we established Hydraulics Online back in 2004, we would be shipping hydraulic parts and offering advice to customers around the entire globe. Yet, this is now exactly what we do – to 129 countries to be precise at the last count. Thanks to the hard work of our team, Hydraulics Online is now a truly global hydraulics business.

This achievement was recognised at the end of November when our local Chamber of Commerce in South Cheshire held its annual Business Awards. The awards received their highest ever number of entries, but despite this Hydraulics Online were recognised for an unprecedented three awards, including being announced winner of the International Trader of the Year 2017.

We are thrilled to be named International Trader of the Year in South Cheshire because it perfectly encapsulates our vision of being a business firmly rooted in its local community, yet one that serves a truly global hydraulics customer base.

Dr Kevin Gallimore is Senior Head of Department of Business Management at  Manchester Metropolitan University (MMU), the sponsors of the award. Kevin was a key member of the judging panel.

global hydraulicsAnnouncing us as the category winners, he said: “We were particularly impressed by Hydraulics Online because of their global reach, their clear competitive positioning, their strong business model, and their plans to invest in technology to better understand their customers in a wide variety of markets around the world.”

We were also really excited to have been invited into MMU following our award win by his fellow judge and Associate Head of MMU’s Business Development department, Jie Liu. Jie asked us to talk to her students about Hydraulics Online’s global reach and success, our international market entry strategies and our use of the of the internet as a key part of our strategy.

The win has also brought us some attention from the Department of International Trade (DIT),  and we are hoping to be able to share additional insights with other local businesses through the many wonderful local schemes that the DIT provides.

Veronica Dawson is our local International Trade Adviser, within the DIT’s North West International Trade Team. She shared her excitement of our award success, saying: “What impresses me most about Hydraulics Online is their passion. They understand that excellent customer services are crucial in exports as you are building that business relationship from a distance. If you have enthusiasm and passion and you combine that with excellent customer services – which Hydraulics Online do – you can succeed in exports. I’m very pleased to be working with them, as it is on small businesses like Hydraulics Online that exporting in the UK is based.”

We’re pleased to report that our global hydraulics trade continues to expand. Just in the last quarter, and in addition to returning business, we have served 34 new customers based in 24 different countries – across Europe, USA, Canada, Nigeria, South Africa, the Middle East, Bangladesh, Malaysia and Vietnam.

This continuing growth and reach is really exciting for us. Our customers come to us through our website and via personal recommendation, and the fact that they do so in such numbers is clear evidence that customers far and wide value what Hydraulics Online offers.

We are planning new communications and support strategies in 2018 to help serve our growing international customer base even more. Stay tuned to our blog and social media channels for all the latest news.

Hydraulics Online South Cheshire Awards Hat-Trick

Alsager, Cheshire, UK. December 7, 2017.

South Cheshire based global hydraulic solutions supplier, Hydraulics Online has been recognised for a startling three awards at the South Cheshire Chamber of Commerce 21st Business Awards.  The unprecedented haul at the end of November included:

  • Winner – Excellence in Customer Service
  • Winner – International Trader of the Year
  • Highly Commended – Ambassador of the Year

The ISO 9001 accredited Cheshire hydraulics business was founded in 2004 by directors Helen Baker and Mark Tonks.  Helen said: “We are absolutely delighted.  By allowing our business to be scrutinised and judged by external professionals, all experts in their own fields, it has provided certainty that we are on the right track and that we really do stand out from the crowd.  It has helped to make our vision clearer, and given us an opportunity to pause and reflect on what we have achieved and celebrate our many successes to date.”

Mark commented: “Being recognised for three awards like this is great recognition of the hard work of every member of our team, the high standards we expect of ourselves day in, day out and our team’s shared commitment to always put the customer first.”

The three awards were judged by their sponsors.

Financial planning group, 1825 were the sponsors and judges of the Excellence in Customer Service category.

cheshire hydraulicsDavid Williams Dip PFS, Regional Managing Director at 1825, commented:  “We picked Hydraulics Online Ltd as our winner of the Excellence in Customer Service award for 2017 because they demonstrated a superb customer service approach which has underpinned their business growth.  We found them to be a welcoming and friendly business which interacts well with its customers through their website and social media, but still prefers the ‘old school’ approach of picking up the phone. We also felt that Helen and Mark truly understand the essence of good relationships in business; the incredibly low number of complaints they receive is testament to this.  It is clear to us that they are always seeking to improve and be the ‘best they can be’ – placing real importance on customer feedback.”

Veronica Dawson is the Cheshire hydraulics company’s local International Trade Adviser, North West International Trade Team, Department of International Trade.  She shared her excitement of their award success, saying: “What impresses me most about Hydraulics Online is their passion.  They understand that excellent customer services are crucial in exports as you are building that business relationship from a distance.  If you have enthusiasm and passion and you combine that with excellent customer services – which Hydraulics Online do – you can succeed in exports.  I’m very pleased to be working with them, as it is on smaller businesses like Hydraulics Online that exporting in the UK is based.”

The evening was a celebration of the innovative businesses working to put the South Cheshire region on the global map.  Chamber Chief Executive Paul Colman said all 39 finalists were winners in their own right. “The awards gave us another chance to celebrate inspirational leadership, exceptional vision and brilliant customer service across a wide variety of sectors. South Cheshire is truly blessed with an abundance of business talent,” he said.

Chamber Chairman Shaun Cafferty said the area was well placed to meet the demands of a modern economy. “We have big, small and medium firms, operating in a wide range of industries, all forward-thinking, energised and delivering excellence locally, nationally and often internationally.”

He added: “South Cheshire is a great place to live and work. It’s a great place to be a business in and to employ people and for new companies to set up. We should perhaps shout about that a bit more than we do!”

cheshire hydraulics“Even if we had come away empty-handed on the night we wouldn’t have regretted entering the awards for one minute,” said Helen. She continued: “The whole process was invaluable. But winning two awards, and being highly commended for the third, means we now have an even stronger platform and focus from which we will continue to grow the business in 2018 and beyond. We’re really excited about what lies ahead.”

South Cheshire Chamber Business Awards - 2017 Finalists

No, you’re not seeing double, or even triple! We’re starting November with a bang… We’ve been shortlisted, not for one, not for two, but for three business awards!

You may have read our recent blog about how one of our customers, HypED the University of Edinburgh’s Hyperloop team, was shortlisted for the final of Elon Musk’s Hyperloop challenge. This month we’re excited to bring you news of our own award success: in the South Cheshire Chamber of Commerce Annual Business Awards.

Unlike HypED, we might not be facing the prospect of jetting off to Southern California, but we are just as excited! The event, taking place at Crewe Hall on November 24th, will celebrate the Chamber’s 21st anniversary of the awards.

When we founded Hydraulics Online in 2004, we had a clear ambition to develop it as a business with strong local roots and a global reach – and the three awards for which we’ve been shortlisted are recognition of how hard we have worked to achieve that ambition.

We entered three award categories:

  • Excellence in Customer Service;
  • International Trader of the Year;
  • Ambassador of the Year.

And we’re delighted to report that – from a record number of entries received by the South Cheshire Chamber – we have been shortlisted in each of the three categories we entered.

Excellence in Customer Service

Our shortlisting in the category “Excellence in Customer Service” is down to the great feedback we consistently receive from our customers, they really are our best advocates – we were able to strengthen our case with lots of wonderful testimonials and demonstrate how our customers really are at the heart of everything we do.

Ambassador of the Year

The “Ambassador of the Year” award is designed to celebrate businesses that showcase South Cheshire far beyond the local area. Having grown up in South Cheshire, and with our global presence, commitment to excellent customer service and our technical expertise, we feel Hydraulics Online is a great ambassador for the region – and we’re really pleased the Chamber agrees!

International Trader of the Year

Finally, being shortlisted in the “International Trader of the Year” category demonstrates the international reach of Hydraulics Online. Our customers find us online from all over the world – and we go to some incredible lengths to ensure our orders get to where they need to go… on time, every time!

The South Cheshire Chamber award process has provided a great opportunity for us to take a step back and look at how far we have come – from a make-shift home office in 2004 to the global business we are today.

We now enjoy fabulous working relationships with more than 140 suppliers, have served more than 3,400 unique customers, and have built up a database of over 7,500 customers and prospects who have all come to us organically because of the strength of our brand. And through all of this we have retained our independence.

We are so proud of how far we have come – and we would like to take this opportunity to thank you for coming with us on the journey.

We couldn’t have done it without you – so thank you.

Rigour and Professionalism aren’t just for Blue-Chips!

We might pride ourselves on our friendly and flexible approach here at Hydraulics Online, but that doesn’t mean we skimp on rigour or ensuring best practice

Our Finance & Administration Manager, Joanna explains…

I’m currently the “new girl” at Hydraulics Online – having started with the company at the end of October 2016 to head up the Finance and Administration team. Since then, my feet seem to have hardly touched the ground – there hasn’t been a quiet day, but that is probably one of the reasons why I love it here so much!

One thing that struck me during my interview was the real team focus of the business.  The Director who interviewed me was Helen, and she went to great pains to make sure I felt at ease during the interview, which was, nevertheless, a very in-depth process.  I really got a sense of the flexible and proactive outlook of the whole team here, and I’m pleased to say that has proved true over the time I have been with Hydraulics Online.

A Balancing Act

Balancing this friendly and personal approach with a really professional working ethic is something the whole team is passionate about. Both Helen and I have come from large, blue chip banking groups before coming to Hydraulics Online – so we have had the need for rigour, professionalism, and attention to detail drilled into us throughout our early careers.  It’s really exciting to come to a smaller business like Hydraulics Online in a completely different industry, but with the same commitment to these qualities.

I joined a major British bank straight from University, under its graduate programme; I was with them for 18 years, right up until I joined Hydraulics Online. During this time I worked in the lending centre in Manchester, the credit office in Liverpool, and in relationship banking, before joining the commercial banking relationship team.

This experience has instilled in me a really strong commitment to customer service and relationship building; one that most finance professionals don’t get to put into practice in their day jobs!

Coming to a small team like Hydraulics Online has enabled me to keep this important and rewarding part of my job.  I see every part of the customer experience here – from enquiry to post-sale care – and this isn’t just great for customer satisfaction, it is rewarding for us as staff too.

More than Average

It might seem a little odd to describe a finance job as exciting, but my job here really is!  It is a lot more varied than your average purchase ledger administration. I get to communicate with customers every day – whether by phone or email – and I have such a variety in the work I do.  From collating management information, overseeing the purchase and sales ledgers, sanctioning new credit accounts, identifying and implementing process improvements, and customer liaison, no two days are the same.

The fact that we are talking with people from all over the world, because of the global reach of the company, ensures diverse and interesting conversations! So one of the other rewarding aspects of the job is that I get to use my French and Spanish as part of my day job too.  I was a bit rusty after my time in the bank – so it has been great to have an opportunity to brush up!

Big Ambitions

Like Helen, I am a graduate of Bristol University.  I read Modern Languages there – so I am able to help out when we receive customer enquiries in French or Spanish.  The French probably comes in most handy – although we get enquiries from all over the world, including Latin America.  One of the most unusual emails I helped out with was a sales enquiry which came all the way from French Polynesia.

It’s all about the customers at the end of the day. Although Hydraulics Online is a comparatively small company, it has big ambitions – and the whole team is keen to share information and best practices.  We all work together to achieve this and it comes together really well.

We welcome all feedback from customers – positive and negative – although I am happy to say that the negative is very rare.  I work very closely with Helen to ensure all feedback is properly responded to, and I’d like to invite all readers to share their thoughts with us too.

Hydraulic Accumulator

A hydraulic accumulator can allow a system to increase its cost-effectiveness, offer continuous, dependable operation and can store emergency power should there be an electrical failure…

Hydraulic systems often include a hydraulic accumulator. They have two functions: one, to store energy and two, to smooth out pulsations. If your hydraulic system includes an accumulator it will also be able to operate with a smaller pump. This is because the accumulator is able to store energy from the pump when the demand is lower. The built-up energy is ready for use the moment it is needed and can be released at a rate much higher than that that would be released with the pump on its own.

A hydraulic accumulator can also double-up as surge or pulsation absorbers, just like an air dome used on pulsating piston or rotary pumps. Accumulators cushion the hydraulic hammer, which helps to reduce shocks caused by the quick movement or sudden starting and stopping of power cylinders in a hydraulic circuit.

There are four main types of hydraulic accumulator: the weight-loaded piston-type accumulator, the diaphragm accumulator (also known as a ‘bladder’), spring-type accumulator and the hydro-pneumatic piston type accumulator. The weight-loaded piston-type accumulator was the first to be used, however it is much larger and heavier than a modern piston or bladder accumulator. This version of the piston accumulator and the spring-type are seldom used nowadays, but the hydro-pneumatic accumulators are the kind that are most commonly found in modern hydraulic systems.

What is a hydraulic accumulator used for?

Storing energy – Hydropneumatic accumulators use a gas as well as hydraulic fluid, which can be compressed into smaller volumes at higher pressures. Potential energy is stored in the compressed gas and will be released once it is required. This kind of energy is similar to that of a raised pile driver transferring its huge energy upon the pile. With a piston accumulator, the energy in the compressed gas exerts pressure against the piston separating the gas and hydraulic fluid. This forces the fluid from the cylinder into the system and consequently to the location where it is required.

Pulsation absorption – In a hydraulic system, pumps create the power that needs to be used or stored. The majority of pumps distribute this power in a pulsating flow. As the piston pump is usually used thanks to its ability to operate under high pressure, the pulsations can be damaging to a system working under high pressure. An accumulator cushions the system against the pressure variations.

Shock cushioning – There are a number of hydraulic applications where the driven member of the system makes a sudden stop, which produces a pressure wave that moves back through the system. During operation, this means that the peak pressures that appear are much greater than the usual working pressures. This creates unpleasant noise or in severe circumstances, system failure. The accumulators gas cushion can help to reduce the shock.

Maintaining pressure – When the liquid in a hydraulic system is exposed to rising and falling temperatures, it causes pressure changes. There could also be drops in pressure due to a hydraulic fluid leak. By giving or taking a little bit of the hydraulic fluid, a hydraulic accumulator compensates for pressure changes.

Fluid dispensing – Accumulators are able to distribute small volumes of hydraulic fluid, including as soon as they are required.

Hydraulic AccumulatorsA couple of examples of some of the projects we’ve undertaken included some Parker bladder accumulators that were for a UK-based electro-mechanical equipment exporter, and then on the right, these accumulators that were despatched to a company who specialise in the services and repair of plant and hydraulics. They were 10 litre nitrile bladder accumulators with elastomeric seals. They have a maximum pressure of 345 bar. We have also dispatched a .75 litre accumulator with a maximum pressure of 350 bar, pressure on port line: 10-70 bar, maximum back pressure on tank line: 3 bar, minimum pressure: 10 bar and oil capacity of 12 litres/minute.

You can find out more about the accumulators we’ve provided in our blogs here and here.

Bonfiglioli Hydraulics - Press Release

Bonfiglioli wheel-traction drives improve precision and efficiency in Huddig revolutionary Tigon Technology backhoe loaders.

Bonfiglioli has designed and developed a dedicated solution to the new full hybrid technology machine created and manufactured by Huddig, a leading backhoe loader manufacturer in Sweden.

Bologna, Italy, March 2, 2017- Bonfiglioli, a leader in the manufacture of gearboxes, gearmotors and drive systems, has announced the development of the 600 series wheel-traction drives – specifically designed for Tigon Technology backhoe loaders, manufactured by Huddig. Each of the special 4-wheel traction drives is capable of reaching an output torque of 40.000 Nm, and is driven by a liquid cooled 30kW electric motor. The independent control of each wheel improves the backhoe loader’s performance on slippery surfaces. The Bonfiglioli 610 drives also increase the precision of the machine, making maneouverability easier in tight spaces, e.g. in building sites located at city centres. And in line with Huddig’s requirements, the 4 drives are perfectly quiet.

Tigon Technology by Huddig, is a hybrid technology that combines diesel and electric power allowing energy generation and regeneration in a way that has never been possible before for construction machinery: the concept machine achieves significantly lower fuel consumption than a traditional backhoe loader. Based on this technology and equipped with Bonfiglioli 4-wheel traction drives, the new Huddig hybrid backhoe loader stands apart from other types of construction equipment without producing emissions.

Bonfiglioli has been designing and manufacturing drives for the construction and off-highway industry for more than 40 years. Already a leader in these markets, Bonfiglioli increased its offering in 2015 with the acquisition of O&K Antriebstechnik and now offers the widest range of final drives on the market, including the largest final drive ever made (up to 3000 kNm torque). Over 30 years ago, Bonfiglioli combined its competence in electric motors with expertise in final drives to begin producing electric and hybrid technology products for mobile equipment, and now offers a complete portfolio of electromobility solutions – find out more about the Bonfiglioli product range here.

Back to our new customer down in Antarctica…

When we say we trade the world over, we aren’t joking! A recent enquiry came from a new customer in Antarctica, who sent the team a photo of a hydraulic pump. Not knowing what they wanted and with the identification plate missing from the unit, the team were tasked with finding out what type of hydraulic pump it was. We never back away from a challenge!

Surely enough, the team identified the pump as a Denison P Series tandem pump and were able to quote on a seal kit to needed to undertake some important repairs on the pump; the pump came from a pristine environment into which the unit had been leaking – a repair was essential.

But sometimes a repair may just not be feasible, providing poor or unreliable performance at best. If this is what we find, we will always contact you to explain why and to quote for a brand new replacement pump.

Hydraulic Gear Pump

Looking for a hydraulic gear pump? We offer extensive access to a vast range of hydraulic manufacturers from around the world…

Hydraulic manufacturersParker, Roquet, Bosch Rexroth, Casappa, Eaton, Caproni, Turolla, Vivoil Vivolo, Ronzio, Salami and Bondioli and Pavesi are just some of the hydraulic gear pump brands that we regularly supply.

The technical team here at Hydraulics Online have more than 75 years’ combined experience between them, so don’t worry if you don’t know what you’re looking for, or can’t identify an existing pump that you’re trying to replace. Leave that to us. And with our ISO 9001 accreditation, you can relax knowing that you’re in capable hands.

Hydraulic gear pump

Large or small, a hydraulic gear pump is a simple and economical pump that creates pressure through the meshing of the gear teeth, forcing fluid around the gears to pressurize the outlet side. They may be quite loud during operation, but modern gear pumps are hugely dependable and much quieter than their older counterparts.

A hydraulic gear pump can be found in a variety of hydraulic systems. They have few moving parts, work effortlessly, and operate easily even with pressures of up to 250 bar. The displacement chambers are located between the housing of the pump and the rotating gear wheel.

There are two main types of hydraulic gear pump…

External hydraulic gear pump

External gear pumps – These pumps are typically found in industrial and mobile applications, e.g. log splitters and lifts. Some of the features of this pump include:

  • Light-weight;
  • High working pressures;
  • Variety of speeds;
  • Large temperature and viscosity range (i.e. flexibility);
  • Low cost.

Internal hydraulic gear pump

Internal gear pumps – These pumps are used predominantly in non-mobile applications e.g. machine tools and presses or fork-lifts. Key features of the internal gear pump include:

  • Low flow pulsation;
  • Decreased operating noise;
  • High efficiency.

Hydraulics CatalogueAs we said, if you’re not sure what sort of pump would be suitable for your application that’s no problem for our technical team; we are always up for a challenge and can usually work miracles with unrecognisable or seemingly obsolete hydraulic pumps and equipment too. We also undertake hydraulic pump repairs and refurbishment and can often offer “direct equivalents” where it is more cost-effective to do so. Don’t forget to visit our catalogue to see the different types of hydraulic gear pump we supply.

Hydraulic Cylinder

Whether you’re looking for a single or double-acting, tie-rod, marine, subsea or welded hydraulic cylinder, something standard or made-to-order, we have it covered…

Better still, you can relax knowing that you’re dealing with a company with over 75 years’ technical experience, backed by ISO 9001 accreditation… and that means that you’re in safe hands. We never compromise on quality on a hydraulic cylinder. Ever.

… I searched for ages to find the right size hydraulic cylinder and you guys came up trumps. Excellent service… really helpful.

If you’re looking for a “standard” hydraulic cylinder, then hop over to our catalogue where we showcase some of the more popular hydraulic cylinders we have on offer:

Hydraulic cylinder catalogue

If you can’t find what you’re looking for, you can always contact one of our hydraulic engineers – they love to talk – or fill in a stock enquiry form. If you’re looking for something a bit different, then our Bespoke Hydraulic Cylinder Design Form will help you capture the information we need to design a custom-made hydraulic cylinder tailored to your specific requirements and operating parameters. Just fill in as much as you can… we can work through the rest together afterwards.

Let’s take a quick look at the different types of hydraulic cylinder design available…

Tie Rod Cylinder: Tie rod style hydraulic cylinders use high-strength threaded steel rods to hold the two end caps to the cylinder barrel. This technique is most often seen in industrial factory applications. Small bore cylinders usually have 4 tie rods, while large bore cylinders could need as many as 16 or 20 tie rods to be able to keep the end caps under the extreme forces generated.

Welded Cylinder: A welded body hydraulic cylinder doesn’t have tie rods. The barrel is welded directly to the end caps; the ports are welded to the barrel; the front rod gland is then usually threaded into or bolted to the cylinder barrel. This enables the piston rod assembly and the rod seals to be removed for service.

Telescopic Cylinder: The length of a hydraulic cylinder is the total of the stroke, the thickness of the piston, the thickness of bottom and head and the length of the connections. If this total length does not fit in the space available, then a telescopic hydraulic cylinder enables the piston rod to also be used as a piston barrel housing a smaller second piston rod.

Plunger Cylinder: A plunger cylinder can only be used as a pushing cylinder; the maximum force is piston rod area multiplied by pressure. This generally means that a piston cylinder has a relatively thick piston rod.

Differential Cylinders: A differential hydraulic cylinder moves like a normal cylinder when pulling. However, If the hydraulic cylinder has to push, the hydraulic oil from the piston rod side of the cylinder is not returned to the reservoir, but instead is forced to the bottom side of the cylinder. This means the cylinder moves much faster, but the maximum force the cylinder can give is like a plunger cylinder. A differential cylinder can be manufactured like a normal cylinder, only a special control is added.

Rephasing Cylinders: Rephasing hydraulic cylinders are a combination of two or more cylinders plumbed in series or parallel, with the bores and rods sized such that all rods extend and/or retract equally when flow is directed to the first, or last, cylinder within the hydraulic system. In “parallel” applications, the bore and rod sizes remain the same, and the hydraulic cylinders are always used in pairs.

Single and Double-Acting Cylinders: A double-acting hydraulic cylinder is a cylinder in which the working fluid acts alternately on both sides of the piston. It has a port at both ends, provided with hydraulic fluid for both the retraction and extension of the piston. A double-acting hydraulic cylinder is used where an external force is not available to retract the piston or where high force is required in both directions of travel. With a single-acting cylinder, when fluid flow is applied to a port in the closed end, the shaft extends until the collar or piston reaches the shaft end. When an external weight or load is placed on the shaft, the shaft will retract into the chamber until the piston or collar reaches the closed end. The cylinder generates an output force at the shaft end in proportion to its internal closed end area multiplied times the pressure potential of the fluid power system.

Can you let the boys know that they are providing us with great service, parts and information in all our locations. Your service is prompt and reliable; you’re our “go to” guys when it comes to hydraulics.

We’ve supplied hydraulic cylinders to customers all over the world, literally, in a vast range of markets…

Hydraulic Cylinders… including an international refuse and waste management services company who needed a number of 3-stage telescopic, double-acting hydraulic cylinders, and a power transmission equipment manufacturer who needed a complete hydraulic system and hydraulic cylinders for a tipping hopper application.

Welded Hydraulic Cylinders

Then there was the new overseas customer, a leading product design and manufacturing company within the renewable energy industry, who contacted our technical team needing support on a new product development project. Having used a tie-rod cylinder within one of their product designs before, they wanted to prototype a welded construction hydraulic cylinder instead. The cylinders (pictured right) were made to order for the customer… Remember that bespoke cylinder design service we spoke about?

 

These bespoke double-acting hydraulic cylinders pictured were designed as part of a bigger system design project for a new prototype machine for a British Original Equipment Manufacturer. We love bringing ideas to life!

 

And finally… If you’re just looking for technical information, then the good news is that we have a number of articles that may be of interest: how hydraulic cylinders work, hydraulic cylinder maintenance, hydraulic cylinder seals, hydraulic cylinder testing, hydraulic cylinder repair and hydraulic cylinder storage.
