Pumping Accessories

Back Pressure Valves - A back pressure valve keeps a positive head on the discharge side of the pump. That prevents siphoning and eliminates varying dosage rates caused by fluctuating downstream pressure. The valve set pressure is adjustable, and a diaphragm protects the spring from the liquid being pumped.

Pressure Relief Valve - A pressure relief valve relieves over pressure on the discharge side of the pump. That prevents damage to the pump and piping. The valve set pressure is adjustable, and a diaphragm protects the spring from the liquid being pumped.

Pulsation Dampener - Prevents pressure and flow spikes caused by reciprocating piston type pumps.

Calibration Column - A clear PVC tube installed in the suction line of the pump used to precisely measure the pump output at different pump dial settings and operating conditions.
