PM50 hand pumps are single delivery and lever operated hydraulic pumps. They are suitable for operating single-acting or plunging hydraulic cylinders. The displacement, fixed, is 50cc/cycle. The double pumping cycle generates pressure in both lever movements. The value of the displacement is thus referred to the operation of the pump in both directions. Typical use for this type of hand pumps is in the implementation of emergency controls. PM50 pumps require panel mounting. To aspirate the fluid from the tank, connect a hose to the inlet port.
