FLOWMASTER Automatic Water System Pump SDP-50 Series 12V 24V DC Electric Diaphragm Pump 6L/min 40PSI
FLOWMASTERTM Automatic Water System Pump 2 Chamber with High Suction Capacity 6.0LPM 40PSI
FLOWMASTERTM SDP-50 series Pumps are designed for a wide range of applications and are constructed from a selection of materials suitable for handling a broad range of chemicals. KDP-50 series of diaphragm pumps are self-priming and can be run dry without harm. They are 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.
Everything from the back flow preventer, check valves, bearings and diaphragm assembly to the motor, have been designed to make this truly the most advanced and reliable diaphragm pump available. Higher efficiency of the pump is evident in the longer life of the motor pump unit. The new diaphragm design combined with the new valves makes the pump capable of pulling higher dry vacuum. SDP-50 series are available in various performance ranges, voltages and with a choice of elastomers, making it easily adaptable to a diverse range of applications.
Typical pump uses are liquid transfer, spraying, cooling, circulation, filtration and dispensing.
