Poclain PM20-21 Axial Piston Medium Duty Pump

Poclain PM20-21 Axial Piston Medium Duty Pump is a variable displacement pump designed for closed-loop hydrostatic transmissions. With a swashplate mechanism it has continuous flow in both forward and reverse directions, flow is directly related to rotation speed and swashplate angle. This model can be configured with multiple control options, servo mechanical, servo hydraulic and electro-proportional, to meet various application needs.

With 21 cm³/rev displacement the PM20-21 has a theoretical flow of 75.6 L/min at 3600 rpm. Rated pressure is 250 bar (3625 PSI) and maximum pressure is 370 bar (5366 PSI) making it suitable for medium duty applications where consistency and reliability is required. An optional charge pump maintains circuit pressure, prevents cavitation and ensures steady operation. The design is robust to ensure long life even in harsh conditions.

Available with high pressure relief valves, flushing valves and various accessories for system protection and customization. The pump is available in single and tandem and can rotate clockwise or counter clockwise. With SAE B mounting flange it’s easy to integrate into different hydraulic systems. All this makes the PM20-21 the perfect pump for applications that need hydraulic power to be efficient, adaptable and robust.
