Product Information :
The Flojet D3621H1212AR is a Flojet Duplex II Diaphragm Pump, with Polypropylene Body Construction, EPDM Diaphragm, Santoprene Check Valve, Low Pressure Cam, NO Switch, 30 PSI Pressure Bypass with 3/8 inch NPT Female Ports, mounted to a 115 Volt AC Motor. This Duplex II series pump incorporates the best technology and features developed by Flojet. It has a new diaphragm design combined with new valve design to make the pump capable of pulling higher dry vacuum. This pump is self-priming up to 8 feet (2.4 m), and can run dry without damage. The vertical prime may vary depending on the fluid viscosity, suction tube size, foot valve and pump configuration. The pump should be mounted in a dry and adequately ventilated area. If mounting the pump in an outdoor environment the pump should be shielded from water, dust, sunlight and wash down spray. This pump is equipped with an external bypass system that bypasses flow internally when pressure is over 30 PSI. It is designed to pump at high pressures while at low or high flow rates, and will continue to run until the power is manually turned off. This pump is not recommended for continuous duty service due to limited motor brush life. Operation at lower pressures and temperatures, however, will extend overall pump service life. The motor on this pump is a Permanent Magnet type with a solid state rectifier and full RFI Suppression. The hertz cycle on this motor is 50/60 Hz. It is intended for intermittent duty cycles but can be run continuously for short periods of time. The higher the duty cycle the shorter the expected life of the pump. IMPORTANT : Do NOT use this to pump Flammable Fluids, Gasoline, Kerosene Fuel Oil, etc. Do NOT use this pump in an Explosive Environment. The maximum temperature for this pump is 140 degrees F degrees F.
WEIGHT : The Flojet D3621H1212AR weighs 5 lbs. Lbs.

Applications
The Flojet D3621H1212AR Duplex II Pump is designed for a wide range of applications and is constructed from a selection of materials suitable for handling a broad range of chemicals. Typical pump uses are liquid transfer, spraying, cooling, circulation, filtration and dispensing. This pump is generally used for general Industrial applications. If pumping a liquid other than water the pump should be flushed with water if applicable after each use. Sealers and Teflon tape acting as a lubricant can cause cracked housings or stripped threads due to over tightening. Care should be used when applying sealers; the tape may enter the pump inhibiting valve action, causing no prime or no shutoff conditions. Failures due to foreign debris are not covered under warranty. Before freezing conditions occur, the pump must be liquid free or winterized with proper antifreezing chemicals. To start and prime the pump, the discharge line must be open allowing trapped air to escape thus avoiding the potential of airlock. Use flexible hose of the correct pressure rating that is compatible with the fluid to be pumped. Tubing should be a minimum of 3/8 inch ID and at least 20 inches in length to avoid excess stress on the pump ports. Do not crimp or kink the tubing. The pump head maybe rotated in 90 degree increments to simplify plumbing. It is not recommended to use metal fittings. The use of check valves in the plumbing system could interfere with the priming ability of the pump. If a check valve is installed in the plumbing it must have a cracking pressure of no more than 2 PSI .14 bar. Use of a minimum 40mesh strainer or filter in the pump inlet line will prevent foreign debris from entering the system. Failures due to foreign debris entering the pump will not be covered under the limited warranty. Note Inlet pressure must not exceed 30PSI 2.1 bar maximum. When wiring electrically driven pumps, follow all electrical and safety codes, as well as the most recent National Electrical Code NEC and the Occupational Safety and Health Act OSHA. Make certain the power source conforms to the pump voltage. Be sure all power is disconnected before installation. The pump should be wired into an individual dedicated circuit, controlled with an UL/CUL certified double pole switch rated at or above the fuse ampere indicated on the pump motor label. On this 115volt AC pump, the black wire lead is live or common, the white lead wire is neutral and the green/yellow is ground. Improper duty cycle and/or rapid start stop conditions caused by undersized spray nozzles will cause the internal thermal breaker if equipped to trip, or can cause premature motor failure due to excessive heat.
