Frequently Asked Questions

Why does the Extreme Duty pump last longer with harsh chemicals?

Its Geolast diaphragms resist chemicals that contain petroleum products, which can break down standard Santoprene diaphragms more quickly.

What is the shut-off pressure?

45 PSI. The demand switch turns the pump off at that pressure when outlets close.

How many amps does it draw?

Up to 16 amps at 12 VDC.

What valves does it use?

Viton valves, with a polypropylene housing and stainless steel fasteners.

Can it run dry?

Yes. It can run dry and self-primes up to 14 feet.
