This is a pressure-actuated regulator that is designed for any pump that fits within the flow and pressure range of the regulator.  The regulator determines the direction of the flow in the system and maintains system pressure via an adjustable knob that controls the amount of tension on a pressure spring.  When the flow stops, it is diverted through the outlet port and all flow is diverted to the bypass port at virtually no pressure.  This regulator design requires a partial bypass to operate.
