Hydraulic Pumps – Preventive Maintenance, Information and Buying Tips

In the fluid power industry there are three main types of these machinery used, which are basically the namely vane, gear, and piston pumps. One will find two different kinds which are used in hydraulic drive systems, these are Hydraulic Pump For Cylinder ​and hydrodynamic. The major differences between the hydrostatic are that these are positive displacement models while hydrodynamic are typically fixed of variable displacements.

These are the usual types which include gear, rotary vane, screw, bent axis, radical piston and axial piston Swashplate principle.

Gear: This type comes with a fixed displacement and external teeth and is suitable for pressures below 3000psi. These are simple to operate, come cheap and are durable. The major cons of a gear model is that it has a limited pressure capability, unbalanced results in large bearing loads, can be noisy and because it is working at a constant displacement, their work is less efficient.

Vane: Hydraulic Pump For Cylinder is chiefly driven by an outside engine that rotates at a continuous speed. Similar amount of fluid is pumped with each rotation, which is regardless of how much pressure there is in the system. Its major advantages are reliability and simple operation. One will certainly find an option of variable displacement and this type has a higher pressure capability as compared to the gear type, as it operates in pressures up to 180 bars. Expensive and more complex are the two major disadvantage of this particular type.

Radial Piston: The Radial Piston pumps are in disparity with axial piston types. These contain pistons that are arranged in symmetrical and radial direction around a drive shaft. The major benefits of these are highly reliable, works efficiently and are capable to create minimum level of noise. This type operates through pressures around 650 bars. Its bigger radial dimensions and higher cost are few drawbacks of this type.
