Original Press Release:



Plunger Metering Pumps with Tamper Resistant Flows



The capacity of JaecoPak(TM) packed plunger metering pumps is adjustable from 0 to 100% of maximum by varying piston stroke length, but only while the pump is stopped, as a safety precaution and for tamper resistance. Available in both simplex and duplex models, pump capacities range from 0.38 to 150 GPH. Stroke rate is easily automated using a variable-speed drive. A single ball check valve, standard on both suction and discharge side of pump, provides accurate metering and fast response. Valve ball turns with fluid flow, constantly presenting a new face to the seat, and is therefore self-cleaning. Pump arms can be reversed to reduce footprint. Duplex pump pistons are normally 180° out of phase, but can be synchronized so that two fluids can be pumped simultaneously. Different size pistons can be used on each side of duplex pumps to produce different outputs. Liquid ends are available in 316 stainless steel or Carpenter alloy 20 from stock. JaecoPak pumps are supplied on base plate with or without motor. A wide range of motor options and accessories are available.
