Pump Accessories – Industrial
Chemical metering pump installations often require piping accessories to insure safe and accurate pumping. Madden offers pump accessories in a number of sizes and materials of construction to fit the design requirements.
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.
