Product Description

Minimize the amount of downtime spent on pump head repairs with this Delavan Quick Change 12V Bypass Diaphragm Pump 5936-117E.

No more having to delay your spraying operation when your diaphragm pump requires a replacement pump head because the patented Quick Change design on these Delavan diaphragm pumps enable you to change pump heads in 60 seconds or less. The quick and easy tool-free method of changing pump heads can be achieved quickly by removing the socket head screw, twisting the pump head to remove it from the motor, connecting the pressure switch to the motor, and twisting on the new pump head and securing the bolt.

The Delavan 5936-117E Quick Change Bypass Diaphragm Pump can be used on small-to-medium sized sprayers, boom sprayers, and wand sprayers for marine and RV applications, fluid transfer applications, agricultural spraying, spot spraying, weed and pest control, lawn / turf spraying, soft wash, and much more. The pump's Santoprene diaphragm and Viton valves provide great chemical resistance, enabling you to pump a range of general use agricultural chemicals, such as liquid fertilizers, herbicides, pesticides, insecticides, and other hard-to-handle fluids.

Powered by a high-torque 12-volt DC electric motor with wire leads and a 2-pin molded connector. The 12V motor provides powerful flow at ideal pressures to ensure smooth and even coverage in your application.

Bypass Pumps feature an internal bypass valve that is useful in applications that require frequent stopping and starting of the motor. Bypass pumps operate at higher pressures while at lower flow rates. They operate even though the discharge side has been stopped, continuing to run until the power is turned off.
