Flojet 3.7 GPM Quad II Automatic 12 Volt DC, 45 PSI, Self Priming Demand Water Pumps are designed for a wide range of applications and are constructed from a selection of materials suitable for handling a broad range of products.
Applications:Automatic water systems, liquid transfer, spraying, cooling, circulation, filtration and dispensing.Operation: These self priming double diaphragm pumps have a built-in pressure switch that will automatically start and stop the pump instantaneously when a discharge valve is opened and closed.Duty Cycle: Intermittent. Can be run continuously for short periods of time. The higher the duty cycle the shorter the expected life of the pump.Special Features:Self priming up to 8 ft. Can run dry for short periods of time. Chemical resistant materials. Heavy duty ball bearing drive system. Built-in back flow preventer Internal bypass: standard Includes: Pump, motor, 2090104 (45 PSI) pressure switch, 20132-000 motor mounting grommet kit. # Two 20381-002 straight 1/2" hose barb adapters.Motor:Permanent magnet, thermally protected 12 volts, DC, 9.0 amps, ball bearingsPump:Two chamber positive displacement opposed diaphragm designPressure setting: 30 PSI Cut-in, 45 PSI Cut-outMaximum Operating Pressure: 40 PSIMaximum suction pressure: 30 PSI Wetted Parts:Modified polypropylene housing, Santoprene diaphragm. EDPM check valves, Priming: Self priming up to 8 ft.Minimum Spray Tip Required: 9/64" (Spraying applications only)Connections: Plug-in ports to accept removable adapters. 3/4" hose barb adapters included (0-ring material EPDM). Other adapters available for easy installation.Dimensions: 4" high, 10" long, 4" wide.Weight:5 lbs
