Low Amp Draw, Reliable Operation

SHURflo’s Classic Potable Water Pump operates three independent pumping chambers which allows the pump to self-prime and lift water up to 12 feet, all the while drawing a maximum of 7 amps of power. This leaves sufficient battery power for other needs, and/or to avoid unnecessary battery drain. With smooth flow and uninterrupted operation, Classic Series pumps include a built-in check valve to prevent back flow into the tank, as well as preset shutoff pressure to prevent system overload of premature failure. In addition, pumps can be mounted in any position and conveniently feature an adjustable switch and the capability to run dry without damage to the pump or motor.
