Poclain PM65 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 mechanical, servo hydraulic, hydraulic automotive, electrical and electro-proportional. Other options include: a flushing valve, filter on charge pressure line and other safety devices.
Poclain PM65 pumps are available in 3 sizes from 55 cc/rev to 65 cc/rev: PM65-55 | PM65-60 | PM65-65
Theoretical flow across the pump series ranges from 198.7 to 234 litres/minute. Rated speeds are 3600 rpm, rated pressure is 250 bar (3625 psi), with maximum pressure of 350 bar (5076 psi).
