Poclain PM20-28 Axial Piston Medium Duty Pump

Poclain PM20-28 Axial Piston Medium Duty Pump is designed for closed-loop hydrostatic transmission applications with variable displacement swashplate. This allows for continuous flow rate in both forward and reverse directions with flow proportional to rotation speed and swashplate angle. The PM20-28 is compatible with multiple control options: servo mechanical, servo hydraulic and electro-proportional control systems.

With a 27.36 cm³/rev displacement the PM20-28 has a theoretical flow rate of 98.6 L/min at 3600 rpm. It’s suitable for medium duty applications where power and control are required. The pump operates at 250 bar (3625 PSI) rated pressure and 370 bar (5366 PSI) max pressure. An integrated charge pump is available to maintain circuit pressure and prevent cavitation and ensure smooth operation. This feature helps to prolong the life of the pump and to have stable performance under variable load.

PM20-28 has high pressure relief valves for system protection and can be optioned with flushing valves, pressure cut off and charge pressure line filters to meet your system requirements. Available in single and tandem configurations, the pump can run clockwise or counterclockwise and can be installed in any hydraulic setup. SAE B mounting flange makes installation easy. Durable and versatile the PM20-28 is perfect for medium duty hydraulic applications that need reliable and efficient power.
