Packed plunger metering pumps

August 20, 2003
Packed plunger, positive displacement metering pumps provide capacities from 0.38 to 150 gph at pressure up to 2,000 psi with an accuracy of 0.5 percent at steady state. Available in both simplex and duplex, field convertible models, they are virtually maintenance-free. Pump capacity is adjustable from 0 to 100 percent of maximum by varying piston stroke length. 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.
