10 GPM 12 Volt Pump

It is a bypass pump, so it can run continuously while you open and close the gun. Santoprene valves and diaphragms stand up to bleach, surfactants and other cleaning chemicals, and the heavy duty reinforced diaphragm is made for demanding use.

Flow at pressure (Delavan chart)

• 0 PSI: about 10.5 GPM, 18 amps
• 20 PSI: about 9 GPM, 23 amps
• 40 PSI: about 7.7 GPM, 29 amps
• 60 PSI: about 6.4 GPM, 33 amps
• 70 PSI: about 5.6 GPM, 35 amps

Good to know

• Inlet and outlet fittings are sold separately.
• Size your wiring, fuse and battery for the amp draw above.

On the Job

The high-flow 12V option. Two diaphragm heads on one high-torque motor push up to 10 GPM, so you get mix onto big roofs and long walls faster than with a 7 GPM pump, while staying on a simple 12V system instead of stepping up to a gas pump. Like our 7 GPM 12V pump, it shoots approximately 30 to 45 feet, with the same reach for roofs, siding and buildings.

It is a bypass pump, so it can run continuously while you open and close the gun, and the Santoprene valves and diaphragms stand up to bleach and surfactants. It draws real current (up to about 35 amps at 70 PSI on Delavan's chart), so size the wiring, fuse and battery for it.
