Unplanned downtime disrupts business operations; effective oil analysis plays a vital role in looking after your machinery…
With 70 to 80 percent of all hydraulic failures being down to fluid contamination, it’s not exactly rocket science to say that ensuring regular, effective oil analysis should always be high on the agenda.
Hydraulic component contamination is categorised in three ways: gaseous, liquid or solid. Gaseous contamination can damage a hydraulic system’s lubricating properties, creating wear and increasing the chances of other types of contamination. Liquid contamination not only alters the capabilities of the lubricating properties, but also causes rust. Solid contamination can cause valve blockages, substantial pump damage and blown seals and gaskets. All of these causes are completely avoidable.
Effective oil analysis – ten ways to keep your oil clean:
1. Monitor – Hydraulic fluid should be monitored routinely and sampled on a quarterly basis.
2. Identify – Identify what sort of contaminant may be present (solid, liquid or gas) to ensure that the right kind of analysis in undertaken.
3. Find the source – By identifying the source of the contamination, preventative action can be taken. This may include contamination as a consequence of the equipment manufacturing process, air borne contamination or contamination produced as a result of the equipment in operation.
4. Neutralise – Offset the causes, and minimise the consequences of contamination either through: oil transfusion, installing extra air filters and replacing worn or damaged components.
5. Benchmark – All oil analysis codes are based off a code: ISO 4406. The relevant benchmark depends on the application in question.
6. Filter – Using hydraulic filters and filtration equipment can, in many cases, stop oil contamination. Determining flow rates, viscosity and pressure are necessary to finding the right filtering system. As a leading hydraulic filter supplier we have widespread, competitive access to both leading and niche hydraulic filter manufacturers from around the world. Some of the hydraulic filter manufacturers and brands that we can supply include: Argo Hytos, Donaldson, Eaton Vickers, Hydac, Ikron, MP Filtri and Parker hydraulic filters. Our technical team will be able to determine which filtration equipment is most suitable for your application.
7. Analyse – In order for oil analysis to be reliable, an in-depth inspection will need to be carried out. This may be in a laboratory environment through microscopic particle count and gravimetric testing, or through a mobile particle counter installed on the machine.
8. Predict – Recording results will allow you to spot trends and identify possible future risks. This is hugely important to lessen unexpected machinery downtime and schedule future inspections in good time.
9. Prevent – To help prevent contamination:
- Always make sure oil is filtered;
- Change oil filters every 12 weeks;
- Take oil samples every 12 weeks to check cleanliness level;
- Install air breathers to reduce contamination.
10. Invest – There is, of course a cost involved in ensuring effective oil analysis, but it is nothing compared to the cost of a replacement pump or even a complete system, lost production and goodwill.

Mark has been a star getting the kit together for a relatively crazy idea I have for an accessory which could have commercial applications beyond us… I’m a relative hydraulic ignoramus and he explained the options brilliantly to me.
It doesn’t matter if your idea isn’t nailed down yet; all we really need is for you to be able to define your end goal. What is it that you want to move, raise, lower, shift, compress, turn, (you get the idea)… how quickly and how often? The team can then show you the best way to get there and we’ll support you all the way through to final production and beyond.
Here are some hydraulic systems we “prepared earlier”…
A UK steel works contacted Hydraulics Online asking us to provide a complete, new hydraulic system capable of moving a 7000kg tool slide in a controlled and timed “stop-start” movement, and also to lift and lock the associated mandrils as required in a continuous cycle.
Hydraulics Online designed a complete bespoke hydraulic system proposing improvements to the customer’s original design and incorporating proportional valve control of the 100 litre/minute and 80 litre / minute pumps that were fitted to the power pack. The complete system was manufactured, installed and commissioned without a hitch!
Moving on from steel to plastic… our engineers were called to the site of a high quality credit, debit and store card manufacturer to fault-find a critical piece of hydraulic equipment and provide a timely solution to production problems. An off-line compatible high pressure (700 bar) hydraulic system was sourced and installed enabling the customer to meet production targets within agreed deadlines and service levels… thus avoiding severe third-party penalties!
There’s more! Our technical team were tasked by a power transmission equipment manufacturer and wholesaler to provide a complete hydraulic system and hydraulic cylinder for a tipping hopper application.
Hydraulics Online specified, designed and supplied a complete hydraulic system including hydraulic power pack and hydraulic actuator. Hydraulic cylinders and mounts were made according to the customer’s specification and the whole package was delivered within budget and time constraints… because we don’t make promises that we can’t keep.
One of our most famous hydraulic systems customers, that we can tell you about anyway, has to be Concorde…
The team were asked if we could help with a project involving Concorde G-AXDN, on display at the Imperial War Museum, to make her the first Concorde in the UK to have a fully functioning droop nose and visor. And the rest, as they say, is history. You can read all about this exciting project here.
I am extremely pleased to have met such a good team who have supported Concorde and Heritage Concorde so well… you deserve a medal! I was amazed; you reeled off figures and technical data that were way above my understanding, but explained things very well. You don’t just shift boxes; you know your business inside and out. A very big “thank you” from the whole team – I hope we can continue the great work.
If you’re happy that your hydraulic systems design is already sorted, then maybe we can help by supplying the equipment and components that are needed to bring it to life. We have access to an extensive range of hydraulic manufacturers from around the world, and can often offer high quality, direct equivalents to big name brands; useful if you need to make your budget stretch that little bit further or have somewhat challenging deadlines to meet!

Our ISO 9001 accreditation is your guarantee that we will never compromise on quality nor make promises that we can’t keep. Aside from obvious routine servicing and maintenance, we want you to be able to “fit and forget” any equipment we supply.
Our catalogue showcases some of the hydraulic cylinders that we regularly supply including: single and double-acting, welded, tie rod and marine hydraulic cylinders.
But back to hydraulic cylinder design… As an example of some of the projects we’ve undertaken in the past, a procurement services company, to offshore, sub-sea and oil and gas industries, contacted the team for pricing and a detailed specification on a bespoke application needing a through-rod (double-rod) hydraulic cylinder. The design parameters were given for a competitor’s product.
Hydraulics Online quoted for an equivalent custom-made through-rod hydraulic cylinder with exactly the same technical specification, which not only had a much more appealing price tag, but also a swifter lead time for the customer. Needless to say, the customer ordered.
Another customer, a leading product design and manufacturing company within the renewable energy industry overseas, asked our technical engineers for help on a new product development plan. The customer had utilised a tie-rod cylinder within one of their product designs before, but this time they wanted to sample a welded construction hydraulic cylinder design instead. No problem. The cylinders here were custom-made and tailored to the customer’s specification and requirements.
There are plenty more case studies and testimonials to be found throughout our website, spanning all manner of applications… in fact it’s hard to think of an industry, market or corner of the world where we haven’t been involved to date. You name it, we’ve probably done it!
So, if you’ve read this far then hopefully you’re tempted to give Hydraulics Online the chance to quote for your hydraulic cylinder design? You can use our Bespoke Hydraulic Cylinder design form to submit your enquiry details to us … or call us talk things through. We’re always happy to talk.

As most of our popular hydraulic components are directly interchangeable with other lesser-known manufacturers, the possibilities are endless.
To bring this to life a little bit, following a search on the internet, a shredding and data disposal company contacted Hydraulics Online asking us to design and supply an efficient hydraulic system to run a mobile compactor and crusher.
Hydraulics Online proposed a hydraulic system using Italgroup radial piston motors. The vehicle was delivered to Hydraulics Online’s premises and our hydraulic engineer installed the PTO driven power source and hydraulic control valves. A second vehicle has since been fitted out to the same specification.
Another example of our work, after being approached by a leading producer of concrete products to civil engineering, construction and agricultural sectors, Hydraulics Online were tasked with replicating an existing, ageing hydraulic system that was no longer available.
The Hydraulics Online design team worked with absolutely minimal information and proposed a much more modern and efficient hydraulic system. This enabled the customer to order and install multiple sets of hydraulic equipment with major cost savings being realised in the process.
Finally, a leading manufacturer of concrete products requested Hydraulics Online to design a complete hydraulic system that would meet the customer’s exact requirements.
A full hydraulic system was designed and supplied comprising single-acting, telescopic lift cylinders and complete power pack. It was successfully installed and commissioned and is now in use in daily production.

Our philosophy is one of not just “taking orders”, unless that’s all that our customers want and need us to do. Instead, we make it our business to understand your business… only then can we be sure that we are supplying you with hydraulic equipment that really is “fit for purpose”. Unfortunately, not everyone shares this way of thinking.
A global specialist vehicle converter, contacted the technical team recently looking for support having been let down by their existing supplier. They had previously taken delivery of a hydraulic power pack that had been incorrectly specified and was simply not suitable for their application; their successful tender for a major new contract was at stake.
Having asked the “right” questions and gathered as much information as they could about the application and its operating parameters, the technical team proposed an alternative system and suggested some additional improvements and safety features that could be made to the design.
Within the week the customer received their hydraulic power pack and additional equipment, and shortly afterwards began to put it through its paces as the prototype platform lift of a commercial vehicle. It worked a treat. The customer then placed an additional order to to enable them to implement our earlier recommendations for additional systems improvements… and we are delighted to say that they won the tender!
So whether you are looking for a relatively standard hydraulic power pack, or a bespoke unit as part of a larger hydraulic systems design project then you’ve come to the right place. You can find out more about the different types of hydraulic power unit here or…

I have just been reminded that we have been working with Hydraulics Online for two years now – since we approached asking if you could help with the nose project on Concorde G-AXDN at the Imperial War Museum, Duxford.
I am extremely pleased to have met such a good team who have supported Concorde and Heritage Concorde so well… you deserve a medal! I was amazed; Mark reeled off figures and technical data that were way above my understanding, but he explained things very well. You don’t just shift boxes; you know your business inside and out. A very big “thank you” from the whole team – I hope we can continue the great work.
Graham Cahill, Head of Heritage Concorde.
You can read more about the project here, and how Hydraulics Online and Heritage Concorde worked together to bring life back to Concorde G-AXDN; she is now the only Concorde in the UK with an operational nose and visor. But for now, here she is with her red nose all set for Comic Relief Day 2015!
It’s a small world at Hydraulics Online – whether delivering our products to customers locally or to customers abroad, we can take the pressure!
We recently had an enquiry from an original equipment manufacturer (OEM) in New Zealand; the company were looking for a hydraulic power pack manufacturer in the UK… to provide a quality, British product. The team at Hydraulics Online have a wealth of experience in building and supplying hydraulic power packs, so we knew exactly what design and specification would work best in the customer’s application (a single-acting, 12v DC hydraulic power pack with flow control) and were able to quote instantly. The customer requested a trial power pack, which we proceeded to build and ship the same day.
After being put through a period of very rigorous testing over a number of weeks, the power pack had more than proved itself… delivering the performance that our OEM was looking for as a key component within his product. As far as an OEM is concerned, having peace of mind and being able to “fit and forget” hydraulic components is clearly vital.
We’re delighted to say that a further ten hydraulic power packs were shipped to New Zealand last week, the first of many given that our hydraulic equipment is now an integral part of this OEM’s core product design… Proof that here at Hydraulics Online, we really do understand the importance of increasing the value of an OEM’s brand and product range. Every project we work on is scrutinized to ensure a successful design and ongoing cost-effective manufacturing, using components that truly are “fit for purpose”.
“We approached Hydraulics Online 18 months ago for assistance in the design and supply of bespoke hydraulic control systems. As a result of their vast technical knowledge and wide product range available, we were able to develop a system which was both competitively priced and completely tailored to suit our application.
Since our initial projects with Hydraulics Online, we have worked together to develop further systems to complement our product range, further heightening our position in the market place. They have also been a valuable technical partner assisting our engineering personnel on site with issues faced in the field. Overall, a valuable tool for any business.” – An appraisal from another satisfied OEM customer.
The hydraulic systems on Concorde 101 G-AXDN had not been used since she was retired in 1977, but with the technical support of Hydraulics Online a plan was created to bring them back to life…
Duxford Aviation Society, owners of the British Airliner Collection, were keen to improve their display of Concorde 101 G-AXDN at the Imperial War Museum. In response, Heritage Concorde proposed making her the first UK Concorde since 2003 to be able to “droop” her nose… and then approached Hydraulics Online asking if we could help on “Project Salute” – we certainly could!
The nose was last lowered in the 1980′s using the emergency free fall system after an attempt to use the aircraft’s hydraulic system had failed. Whilst there was clear support for the latest project there was also, therefore, a great deal of concern and considerable work involved in ensuring that there would be no damage to G-AXDN and that all Health & Safety requirements would be met.
Heritage Concorde provided our team with the technical specification for the Concorde nose systems and then undertook the preparatory work needed to inspect the associated aircraft wiring and nose/visor control systems. The nose is operated by two hydraulic systems - green being the normal and yellow the standby; only the normal system was to be used, in isolation from all of the other hydraulic systems on the aircraft.
Hydraulics Online designed and built a bespoke hydraulic power pack that could be connected to the existing nose hydraulic systems and allow the visor and nose to be lowered and raised at any time; safety features included a pressure gauge and a hydraulic pressure valve. Meanwhile the Heritage Concorde team began the painstaking task of cleaning and preparing the existing nose systems and mechanism and examining the electrical controls for the nose within the cockpit.
The hydraulic power pack was put through a number of rigorous tests before it was connected to the nose system; once installed, the specialist hydraulic mineral oil was added, before bleeding and flushing the system through to remove any remaining debris.
Having been idle for so long, the aircraft hydraulic systems needed to be fully cleaned. After 18 months the project was successfully completed; G-AXDN is now the only Concorde in the UK with an operational nose and visor. Graham Cahill, Director of Projects at Heritage Concorde (pictured centre) commented: “It has been a real pleasure dealing with the team at Hydraulics Online; they have been very accommodating throughout the project, giving expert advice and technical support… We really couldn’t have asked for more.”
David Garside, Chairman of Duxford Aviation Society, unveiled G-AXDN’s droop nose at the Imperial War Museum, Duxford on 24th October, 2014 – timed to coincide with, and “Salute”, the 11th anniversary of the last commercial flight by Concorde. He added: “It is 37 years since Concorde G-AXDN was flown to Duxford and since the hydraulic and electrical systems were last in operation. The restoration projects have required the servicing and overhaul of many intricate components and considerable patience and determination has been required over a two year period to ensure their successful completion… We gratefully acknowledge the generous sponsorship and support from Hydraulics Online Ltd and for designing and supplying the hydraulic power pack.”
Mark Tonks, Managing Director of Hydraulics Online Ltd said: “We were absolutely thrilled when Heritage Concorde asked if we could help on “Project Salute”. Our customer base is global, we’re always involved with a vast range of projects and systems design work and we deal with some big household names… but Concorde is in a different league. Seeing G-AXDN’s nose and visor moving again, knowing that we were part of the team that made it happen, is very special indeed.”
