Poclain PM50 pumps and PMe50 (with electronics) 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: hydraulic, electrical and electro-proportional. Hydraulic and electro-proportional controls can also be equipped with feedback device.
Other options include: a flushing valve and filter on the charge pressure line. Rotation can be clockwise or counterclockwise.
Poclain PM50 and PMe50 pumps are both available in 3 sizes from 40 cc/rev to 52 cc/rev: PM50-40 | PM50-45 | PM50-52 | PM30-35 | PMe30-25 | PMe30-28 | PMe30-30 | PMe30-35
Theoretical flow across the pump series ranges from 144 to 187.2 litres/minute.
