Packed Plunger Metering Pumps 20-682 GPH Flow Rate 65-7,200 PSIG Pressure • Continuous, accurate metering at higher flow rates and/or pressures. • Available in simplex and duplex models FEATURES & BENEFITS • Provides a simple and virtually maintenance-free approach to accurate chemical feed. • Stroke rate easily automated using variable-speed drive. • Capacity is manually adjustable, but only while pump is idle, as a safety precaution and for tamper resistance. • Stroke length is 0 to 100% adjustable for a turn-down ratio of 10:1. • Available with motor or as bare pump. • Single ball check valve, standard on both suction and discharge side of the 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. • Because it is a true positive displacement pump, a safety relief valve on all closed loop systems is required to prevent posssible overpressuring the discharge line. • Integral lantern ring for packing lubricant may be used for internal purging when handling crystallized, corrosive or other hazardous liquids. • Packing adjustment screwed gland nut ensures even take-up and fewer packing problems. • Models 324, 332 and 340 have a clamped column, suction and discharge check valve assembly that can be easily cleaned, inspected or replaced without breaking pipe connections. • Accuracy of ± .5% at steady state. • All units come epoxy painted, completely assembled on a base plate and have been fully tested. PUMP OPTIONS • Double ball check valves with or without spring-loaded balls. • Purge-port plugs, available in cylinder end, can be used to bleed air during and after start-up and to solvent-purge the liquid end. They also provide easy access to the cylinder without breaking pipe connections. MOTOR OPTIONS • Pressure relief valves • Back pressure valves • Calibration columns • Pulsation dampeners • Pressure gauges 316 Stainless Steel Alloy 20 SEALS: Neopre
