Where are hydraulic pumps applied?


A hydraulic pump is the central element of any hydraulic system.

The primary task of the pump is to convert mechanical energy (torque, speed) into hydraulic energy (pressure, volume flow).

Hydraulic pumps operate on the positive displacement principle:
Sealed chambers are formed in the pump through which hydraulic fluid is transported from a tank from the suction port (input side) to the discharge port (output side).

There is no direct connection between the two ports – for this reason, hydraulic pumps are ideal for high system pressure.

Hydraulic pumps are used primarily in mobile machinery. These include for example

Wheel loader
Mining and drilling machines
Mobile cranes
Hand crank drives and
Forestry machinery


LöSi’s high-quality hydraulic pumps can be used for both open and closed hydraulic circuits. They have high efficiency, first-class quality and long service life.

Our team of specialists will be happy to advise you on the optimum hydraulic pump for your system.

What to look for when choosing a hydraulic pump



A hydraulic pump plays a large part in the smooth operation of your hydraulic system. If you consider the following points, you can make a careful selection that makes sense for your operation.

Due to the multi-layered requirements, hydraulic pumps have different designs:

  • Axial piston pumps
  • Vane pumps
  • Radial piston pumps
  • Gear pumps
  • Hydraulic hand pumps
  • Hydraulic pumps 12 V and
  • PTO hydraulic pumps

When purchasing, you should choose a hydraulic pump that is designed for the specific application in your plant, the ambient conditions and the medium used.

Ask yourself whether you want the pump to be constant or adjustable and whether you need two directions of flow.

Also note essential parameters such as displacement per revolution, operating pressure, speed range, tolerances, noise level and efficiency.
