Choosing the right hydraulic pump is one of the most important decisions in any hydraulic system. The pump sets the flow and pressure available to every actuator downstream, and the wrong choice means poor efficiency, overheating or premature failure. This guide explains the main pump types, where Bosch Rexroth pumps fit, and the key factors to weigh when selecting one for your machine in Malaysia.
The main types of hydraulic pump
Hydraulic pumps are positive-displacement devices, and the three families you will meet most often are:
- Gear pumps — simple, robust and cost-effective for fixed-displacement, lower-pressure duties.
- Vane pumps — smooth and quiet, suited to mid-pressure industrial applications.
- Axial piston pumps — the workhorses of high-pressure hydraulics, available as fixed or variable displacement and capable of the highest efficiencies.
You can browse our full range of axial piston pumps and other hydraulic pumps on our product pages.
Where Bosch Rexroth fits
As a Bosch Rexroth Certified Excellence Partner, Twin Hydraulics Engineering supplies the Rexroth axial piston range, including the well-known A10VSO variable-displacement pump used in industrial power units and the larger A4VSO series for demanding applications. Rexroth pumps are valued for their high volumetric efficiency, controllability and long service life, which is why they are specified across manufacturing, steel, marine and mobile equipment.
How to select the right pump
Five questions guide most pump selections:
- Flow rate — how much oil (L/min) your actuators need at full speed.
- Operating pressure — the maximum and continuous working pressure of the system.
- Fixed or variable displacement — variable pumps save energy where demand changes; fixed pumps suit constant duties.
- Control type — pressure compensation, load sensing or electro-hydraulic control.
- Mounting, drive speed and fluid — shaft, flange, rated rpm and fluid compatibility.
