Frequently Asked Questions

Does this pump run continuously?

No. The 7971-104E-SB is a demand pump. It shuts off at 60 PSI when outlets close and restarts when pressure drops, which reduces wear and energy use.

What is the advantage of 3/4" Quick Attach ports?

Quick Attach fittings clip on without threads, so changing hose barbs or adapters is fast and leak-free. The FB3 also comes in a 1/2" FNPT version (7871 series).

How far can it lift liquid?

It self-primes up to 14 feet and can be run dry without damage.

How much current does the motor draw?

The 115/120 VAC totally enclosed motor draws a maximum of 1.5 amps and comes with a 6 foot power cord with plug.

What is the maximum liquid temperature?

140°F. Use it with water and compatible chemicals within that limit, and do not pump flammable liquids.
