Piston Diaphragm PumpsPUMPS Piston Diaphragm Pumps are positive displacement pumps designed to economically transfer small volumes of fluid at low discharge pressures. The lightweight, compact pumps are self-priming, corrosion resistant and can handle viscous fluids. These features make the pumps ideal for high-volume copy machines, scientific and laboratory instruments, and other chemical dispensing applications. Features: • Economical • Self-priming • No dynamic seals • No backflow • Continuous duty rated • Corrosion resistant • Dry run capability Operation: Standard models are constructed with 12 or 24 volt DC solenoids. A switch is required to supply pulsed voltage to the pump. The energized solenoid pulls the piston and diaphragm up, drawing fluid into the pump. A spring forces the piston back to its original position when the solenoid is de-energized, forcing fluid out of the pump, and the cycle is repeated. Valves are utilized to prevent back-flow into the pump and to maintain prime. 180 Hines Ave. • Bellville, OH 44813 • PH: 419-886-3001 • FAX: 419-886-2338 • www.GRIpumps.com GRI Piston Diaphragm Pumps Overview 0818 081718 Pa
