Product Description

24 VDC Duplex II Diaphragm Pump

The Flojet D3231E1311A is constructed with a polypropylene body and EPDM diaphragm and check valve for chemical resistance, makeing it suiatable for an array of commercial and industrial jobs.

This pump has a new diaphragm design combined with new valve design to make the pump capable of pulling higher dry vacuum. It is self-priming up to 8 feet, and can run dry without damage. Vertical prime capability will depend on the fluid viscosity, suction tube size, foot valve and pump configuration.

This pump has an external bypass system that bypasses flow internally when pressure is over 50 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. It is intended for intermittent duty cycles, but can be run continuously for short periods of time. Continuous duty and operation at higher than optimal pressure and temperature can reduce the life of the motor brushes.
