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.
There are a huge range of manufacturers from around the world, designing and making a variety of hydraulic pumps including: gear pumps, rotary vane pumps, fixed displacement / screw pumps, bent axis piston pumps, axial piston pumps, radial piston pumps. As well as offering pumps from all the major brands, we also offer direct equivalents to some of the more well-known hydraulic pump manufacturers… particularly useful if you’re up against tight deadlines, timescales or budgets.
Some of the popular hydraulic pump manufacturers and brands that we can supply, and in many cases offer direct equivalents to include: Adan hydraulic pumps, Atos, Bosch Rexroth, Breuninghaus hydraulic pumps, Bucher, Casappa hydraulic pumps, Commercial, Continental hydraulic pumps, Dowty hydraulic pump, Dynapower, Eaton, Eaton Vickers, Hamworthy, Hydromatik, Kawsaki, Linde, Parker hydraulic pumps, Permco, Poclain, Racine, RHL, Sauer Danfoss / Sauer Sundstrand hydraulic pumps, Salami hydraulic pumps, Tyrone, Uchida hydraulic pumps, Vickers and White hydraulic pumps.

Looking for a hydraulic gear pump? We offer extensive access to a vast range of hydraulic manufacturers from around the world…
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.
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 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:
- High working pressures;
- Variety of speeds;
- Large temperature and viscosity range (i.e. flexibility);
- Low cost.
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.
As 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.
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…
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 Parker pumps 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.
Denison 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.
Denison 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…
But 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.
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?
Even before becoming part of the Parker Group, Commercial Hydraulics was thought of as one of the world’s biggest names in gear pump manufacturing. And now with the Parker name behind them, Commercial Hydraulics continue to lead the way – their gear pump series regularly referred to as the industry standard against which others are measured.
A Parker gear pump is still made to the same demanding standards set by Commercial Hydraulics – the only difference being that the old Commercial product codes are now preceded by “PG” (for Parker Group).
The Parker gear pump / motor range comprises:
- P30, M30, PGP30, PGM30, P31, M31, PGP031, PGM031;
- P50, M50, PGP050, PGM050, P51, M51, PGP051, PGM051;
- P75, PGP075, PGM075, P76, PGP076, PGM076.
Designed for high-torque applications, the P30, P31, P50, P51, P75, P76 Parker gear pump series offer a wide variety of drive shafts, with unique pressure-balanced thrust plates contributing to optimal performance. Manufactured with hi-tensile grey iron, such a Parker gear pump can be supplied in single and multiple section configurations, with a choice of (relief) valve options.
- P315, PGP315, PGM315;
- P330, PGP330, PGM330;
- P350, PGP350, PGM350;
- P365, PGP365, PGM365.
The PGP / PGM 300 Parker gear pump series delivers superior reliability and performance in even the most demanding of heavy-duty hydraulic applications. The three-piece cast iron construction with large area, low-friction bushings means that this Parker gear pump series provides strength, high efficiency, and long life in severe operating environments. The design includes an advanced thrust plate and seal configuration, which optimizes performance even in high temperature and low viscosity conditions.
Here at Hydraulics Online, we know that time and money are precious commodities, and that in a “real time” world that never sleeps, you can often find yourself needing something “yesterday” … with a budget under pressure to stretch ever further. Again. That’s why we also offer a range of completely interchangeable, direct equivalents to the Commercial Parker gear pump range. Built and tested here in the UK, you can be assured of a quality product that can more often than not be dispatched within 24 hours.
Our experienced technical sales team are a lovely bunch and will be more than happy to advise you on Commercial / Parker gear pumps if you are looking for more help and technical guidance… Or even a miracle!
And in the meantime we’ll close with this unsolicited “thank you” from a new customer, received after they took delivery of their Parker P76 gear pump. They have since ordered another to hold as a spare:
I write to thank you for your assistance in delivering a replacement Parker tandem pump for our vessel “Adeline”. The pump was installed on the main engine reduction gearbox this morning and has been successfully tested in all operating modes. Your help was much appreciated, good weekend to you and your team.
Technical Director – Worldwide ship management services company.

- Compact, service-friendly design with flexible mounting interface;
- Quiet operation;
- High operating efficiency for lower power consumption and reduced heat generation;
- Simple hydraulic controls with “no-leak” adjustments;
- High self-priming speed capabilities;
- Modular compensators with fast response;
- FEM optimized housing and pre-compression chamber resulting in low output, pulsation and less noise to insulate.
With quality in-demand products, lead times can sometimes become protracted creating a challenge for end users and original equipment manufacturers alike. But here at Hydraulics Online we like a challenge…
As an example, a company specialising in the design and manufacture of heat exchangers contacted our technical team requiring 5 Parker PV Series axial piston pumps on a quick delivery time. They had already contacted a number of other hydraulic suppliers, only to be consistently told that delivery times would be 8-10 weeks. We tried harder…
Our technical sales team have a wealth of knowledge between them, over 75 years to be precise, and don’t like to be beaten. And they weren’t. We were able to quote the 5 Parker axial piston pumps that the customer needed on a much reduced 5 week lead time. And, as an ISO 9001 accredited company we consistently deliver against our promises and do what we say we’re going to do. The result? Another very happy customer who took delivery of his Parker PVplus pumps in just over half the time that he had originally been led to believe would be possible.
We export to over 150 countries worldwide – technology and extensive carrier networks actually make the world a very small place – and in addition to Parker PV series axial piston pumps, we supply a huge range of other hydraulic pumps including: gear pumps, rotary vane pumps, fixed displacement pumps / screw pumps, bent axis piston pumps, axial piston pumps and radial piston pumps. If you’re up against particularly tight deadlines or budgets, we can often offer quality, direct equivalents to well-known hydraulic brands, then there’s our hydraulic repair service offering an alternative cost-effective solution for you.
If you’re not sure on what sort of hydraulic pump you need, our experienced technical team can help determine the one that will be best suited to your application. As we’ve shown, we’re always up for a challenge and can usually work miracles with seemingly obsolete hydraulic pumps too! Our catalogue showcases some of the hydraulic pumps, and other products, that we regularly supply – but it really is just a sample, so if you can’t find what you’re looking for then we’re confident that we’ll still be able to help.

Parker T6, T67 and T7 series vane pumps have been designed specially for high or low circuits. With a variety of different cartridges in double and triple pumps, the vane pump allows low flow at high pressure (300 bar max.) and high flow at lower pressure. This allows enhancement in your circuit design and allow a very fast pressure cycle change with a very precise flow. Other features and benefits of the Parker T6, T67 and T7 series include the:
- pumps’ ability to reach a pressure of up to 4650 PSI, meaning that fitting costs are lessened and it delivers prolonged life at reduced pressure;
- high volumetric efficiency, typically better than 94%, which reduces heat generation and allows speeds down to 600 RPM at full pressure;
- high mechanical efficiency, typically better than 94%, which reduces energy consumption;
- wide speed range (600 RPM at 3600 RPM) which, combined with large size cartridge displacements, improves operation for the lowest noise level;
- low speed (600 RPM), low pressure, high viscosity (3900 SUS) allowing an application to run in cold environments with little energy consumption and without risk of seizure;
- low ripple pressure (± 29 PSI) lessening piping noise and increasing lifetime of other components in the circuit;
- greater resistance to particle contamination with increased pump life, due to the double lip vane;
- diverse range of options (cam displacement, shaft, porting) allowing for a customised installation;
- improved the low noise level features;
- high performance functionality and durability even in the toughest environments including: commercial, mobile, industrial and aerospace applications.
