Innovative Custom Hydraulics and Systems Design

We invest time and energy to build great relationships with our suppliers as well as our customers. Fluidlink Hydraulics is a British manufacturer of mobile hydraulic power packs and valve packs. It has worked closely with us for more than ten years – helping us to deliver the innovative custom hydraulics and  high-tech solutions for which we’re known.

We work with Hydraulics Online to provide solutions that other companies wouldn’t be able to – Martin Belbin, Operations & Technical Manager, Fluidlink Hydraulics

As a quality British engineering business, Fluidlink Hydraulics invests heavily in its machinery, software, skills and technology and operates a 100% testing protocol.  The vast majority of its customers use Fluidlink for the design, manufacture and build service it offers to OEM clients.  However, its partnership with Hydraulics Online brings some more unusual and technically challenging custom hydraulics work its way.

Custom Hydraulics – Engineering Bespoke Solutions

Fluidlink Hydraulic’s Operations & Technical Manager, Martin Belbin, says: “Hydraulics Online are always different.  We’ve manufactured a bespoke power pack for the hydraulic systems to lift a 400kg marble kitchen worktop. We’ve even manufactured a system to control the nose on Concorde.  Because we have manufacturing capability here, we can be very flexible and make very small quantities and one-offs if required.”

The businesses have been working closely together since 2006 and Martin says the two companies complement each other well.

“The power packs we manufacture are only one component in a hydraulic solution.  You also need cylinders, motors, hoses, and the control gear.  Not only does Hydraulics Online have very good relationships with the distributors of these other components, they also have the product knowledge that goes along with them.”

“They can take our designs and say ‘if we put it with this component, it will work in that application’.  It means we can work together to develop an optimal custom hydraulics solution.  Hydraulics Online is completely independent, so we can choose the best components for the job and, most importantly, we can be very competitive on price.”

Good Collaboration

As well as developing a range of power packs for Hydraulics Online, it isn’t uncommon for the two businesses to take a brief from the end customer together in order to work closely on the design stages of a project.

“When a client has an unusual requirement, Hydraulics Online will do the initial problem-solving for them, then we can do the bespoke engineering side behind it.  Combining the products and product knowledge of Hydraulics Online and integrating that with our bespoke solutions is the best of both worlds,” says Martin.

A Very Unusual Requirement

This teamwork paid dividends on a very usual job in early 2017.  A client approached Hydraulics Online for a very particular set of requirements for operating an extruding machine.  It needed to run a very large cylinder very slowly at the same time as a hydraulic motor was required to turn quickly.  Martin says: “it was the two extremes of hydraulics in a single system”.

The client had a very specific set of requirements, so it was important that all three companies worked together so an appropriate solution could be offered.

Our relationship with Hydraulics Online means that we are able to be very competitive – Martin Belbin, Operations & Technical Manager, Fluidlink Hydraulics

fluidlink-1Despite the complexity and unconventional specification, the close working relationship enabled Hydraulics Online and Fluidlink to design and propose a solution within two weeks, with just another four weeks required to manufacture, build and deliver it once approved.

The finished solution included both a 11Kw motor coupled with a large 18cc pump capable of producing a flow rate of 27L per minute at 200 bar pressure, and a 0.25Kw with a 0.166cc pump delivering a flow rate of 0.01L per minute under 200 bar of pressure, plus a 100L tank and a single power pack on a large frame that fit the client’s exact dimensions.  This involved a bespoke distribution manifold and a bespoke control manifold built by Fluidlink Hydraulics, so that all aspects could be controlled, including setting the speed and torque on the motors.

Martin says: “We love working with Hydraulics Online.  Their technical knowledge is excellent. They have all sorts of challenging enquiries which makes life very interesting.  Because of our combined expertise, when we work with them, we know we are going to be able to push the boundaries a bit and think outside the box.”

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.

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.

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.

Parker Pumps

With our competitive access to a vast range of hydraulic equipment manufacturers and over 75 years’ technical experience behind us, it’s hardly surprising that our customer base covers such a vast range of industries and applications all over the world for Parker pumps…

In fact if you named a market or country, we’re confident that we’ll be able to tell you about a customer or project that we’ve been involved with. We do, however, seem to attract a great deal of custom from marine, ship management and offshore services companies. Take, for example, the case of this overseas company looking for a Parker pump for one of their vessels…

The company, whose vessels are used in offshore operations for one of the largest oil producers in the world, first contacted Hydraulic Online when they needed a number of Parker pumps – Denison T6C Series vane pumps – for one of their vessels.

Parker HydraulicsDenison Hydraulics is part of the Parker Hannifin group, and as such a leading industrial manufacturer who provides highly engineered hydraulic fluid power systems and hydraulic equipment that can be found in a multitude of applications ranging from: mobile equipment used in the construction, demolition, agricultural, mining and utilities industries to machinery found in industrial manufacturing and marine equipment for commercial and military ships alike.

T6 T67 T7 Parker pumpsDenison vane pumps remain operational at pressures exceeding 4,500 pounds per square inch, differ in size from 0.35 cubic inches to 16 cubic inches, and in displacement from 1 to 250 gallons per minute. These Parker pumps, considered to be some of the toughest components in the industry, are often recognised by their distinctive double-lip design, where the vane is in contact with the cam ring at two points as opposed to one, which is the single-lip design. This double-lip design decreases the vulnerability to contamination when compared to single-lip pumps.

You can find more information on the full range of Commercial Hydraulics Parker pumps by clicking here. 

Anyway, back to our customer… we quoted for the T6 Parker Pumps (and some Veljan vane pumps as well), apparently beating off competition from another overseas supplier local to our customer. And the rest is history…

Bow thrusterBut it doesn’t stop there… the customer was so impressed with our service, that they immediately asked us to quote for a replacement double servo pump that to be used on the bow thruster system on another one of their vessels. Thrusters are mounted to the bow of the vessel to make docking easier; they enable the ship to turn to port or starboard side, without having to use the main propulsion mechanism which involves some forward motion for turning.

Parker servo pump

As is often the case, the customer sent in a photo (shown here) and asked our technical team to identify their existing pump (Commercial Hydraulics P31 series, Parker pumps) and quote for a replacement unit… which we did. The customer received their replacement pumps within a week of placing their order and quickly had the vessel back servicing oil rigs in the North Sea!

Our customers really are our best advocates, and we have plenty more case studies and testimonials, if you would like to take a look… Maybe your story might feature in our growing library one day too?
