pressure ratio. The pressure ratio determines the maximum outlet pressure.
SC compact liquid pumps cycle automatically. When compressed air is first applied to the pump, it will cycle at its maximum speed producing maximum flow. At
this stage, the pump is acting as a transfer pump filling the pressure receiver with liquid. The pump will then gradually start to cycle at a slower rate as the
pressure in the receiver increases and offers more resistance to the reciprocating differential piston.
SC pumps stop automatically when the output pressure force and the air drive force is balanced to create a stall condition. At this point, the pump will
maintain pressure without energy consumption, thus providing an economical source for hydraulic power.
