Poclain PM25 Axial Piston Pumps

Poclain PM25 pumps are variable displacement axial piston pumps with a swash plate design. They are for use in closed circuit hydrostatic transmissions.

These pumps are equipped with high pressure relief valves and can be delivered with auxiliary gear pumps; they are are available as single or tandem pumps.

They provide a continuously variable flow rate between zero and maximum in forward and reverse direction. Flow rate is proportional to rotation speed and the swashplate angle.

A charge pump can also be used to keep the circuit pressurised. This avoids risk of cavitation and ensures a good performance of the transmission.

Several types of control are available for these pumps: servo hydraulic, hydraulic automotive, direct or servo mechanical, electrical and electro-proportional. Other options include: a flushing valve, filter on charge pressure line and other safety devices.

Poclain PM25 pumps are available in 3 sizes from 20 cc/rev to 28 cc/rev: PM25-20 | PM25-25 | PM25-28

Theoretical flow across the pump series ranges from 73.8 to 100.8 litres/minute. Rated speeds are 3600 rpm, rated pressure is 250 bar (3625 psi), with maximum pressure of 350 bar (5076 psi).
