Utility Self-Priming Trash Pumps

PRODUCTS > Utility Self-Priming Trash Pumps

Thompson’s utility trash pumps provide high performance with the mobility of lightweight cast aluminum housing.

With a replaceable volute, housing, impeller, and wear plate, worn parts can be easily swapped out in the field, saving time and money. For durability, portability and flexibility, Thompson’s Utility Self-Priming Trash Pump performs over the long haul with low maintenance for continued service.



This pump requires the casing to be initially filled with water prior to operation. As the impeller turns, the center of the impeller will create a low-pressure area, and the water and air will slowly separate with water recirculating inside the pump casing. Air will then escape through the discharge allowing the pump to achieve full prime.
