Rotary Piston Pump
Up to 40 GPM - Series 40

Rotary Piston Pumps Up to 40 GPM - Series 40

This unique design offers all the advantages of a relief valve placed directly in the line. This specially constructed relief valve bypasses flow directly from the discharge to the suction port. Discharge may be restricted of blocked entirely without shock or chatter. However heat will be generated over time. Design is extremely compact because the valve is a part of the pump head itself. For additional details see description under Model 20DX.
