Self-Priming Pumps

Ideal for handling high volumes of liquids containing sewage and other solids, self-priming sewage/trash pumps are close-coupled to continuous-duty motors and designed to be installed in a stationary application. They can be used in most industrial and commercial facilities in process, liquid transfer, irrigation, clear or gray water, and sewage treatment applications. Portable, self-priming utility pumps use an air-water mixture to reach a fully-primed pumping condition. Ideal for lawn watering, pumping out flooded basements, bailing out boats, and boosting water pressure. Pumps feature lubricated, shielded ball bearings and external brush holders. Durable and corrosion-resistant pressure pumps have built-in thermal overload protection and a fiberglass-reinforced pump body that’s specially fitted to resist seawater and saltwater. Grainger has a large selection of self priming pumps suitable for most applications.
