Hydraulics Online has widespread, competitive access to both leading and niche hydraulic pump manufacturers from around the world. Whether you need: Eaton Vickers hydraulic pumps, Sauer Danfoss, Denison, Casappa hydraulic pumps, Bosch Rexroth hydraulic pumps, Char-Lynn hydraulic pumps, Dowty hydraulic pumps, Racine hydraulic pump, Poclain hydraulic pump or even an unrecognisable or obsolete hydraulic pump… we’re confident we can find the one you’re looking for. The logo links below show just some of the hydraulic pump manufacturers and brands that we can supply. But don’t worry if you’re not sure on what sort of hydraulic pump you need; our experienced team can help determine the one that will be best suited to your application.
If you’re up against tight timescales or challenging budgets we can also usually offer direct equivalents to many of the better known hydraulic pumps; and don’t forget our hydraulic pump repair service which may sometimes provide an alternative viable solution for you.

We supply a wide range of hydraulic pump types including:
- GEAR PUMPS: simple and economical, creating pressure through the meshing of the gear teeth, which forces fluid around the gears to pressurize the outlet side. These hydraulic pumps can be quite noisy, but modern gear pumps are highly reliable and much quieter than older models;
- ROTARY VANE PUMPS: have higher efficiencies than gear pumps, but are also used for mid- pressures up to 180 bars in general;
- SCREW PUMPS: also known as a fixed displacement pump, are used for high flows and relatively low pressure (max 100 bar). The advantage of the screw pumps is the low sound level, but the efficiency is not that high;
- BENT AXIS PUMPS: These have the best efficiency of all hydraulic pumps. In general the largest displacements are approximately one litre per revolution, although a two-litre swept volume hydraulic pump can be built. Variable-displacement pumps are often used, where the oil flow can be adjusted carefully and can operate with a working pressure of up to 350–420 bars in continuous work;
- AXIAL PISTON PUMPS: These hydraulic pumps have the advantage of being more compact in design and are easier and more economical to manufacture; the disadvantage is that they are more sensitive to oil contamination;
- RADIAL PISTON PUMPS: (fixed displacement) are used especially for high pressure and relatively small flows. Pressures of up to 650 bar are normal. In fact variable displacement is not possible, but sometimes the hydraulic pump is designed in such a way that the plungers can be switched off one by one, so that a sort of variable displacement pump is obtained.
