Heavy-Duty Trash Pumps

PRODUCTS > Heavy-Duty Trash Pumps

Thompson’s trash pumps are the preferred pumps for tough jobs where a wet priming pump capable of handling large solids or abrasive material is needed.

The heavy-duty construction provides longer life, economical operations, and lower fuel costs. The quality and dependability engineered into each heavy-duty trash pump provide the high performance you need to get the job done quickly. Thompson’s rugged trash pump provides an economical self-primer with simple low-cost maintenance for flood control, dewatering and sewage bypass. Able to handle solids up to 3 inches, the HT is available in sizes from 4 to 8 inches.



Thompson’s HT pumps require the casing to be initially filled with water prior to operation. As the impeller turns, the center of the impeller creates a low-pressure area allowing the water and air to separate with water recirculating inside the pump casing. Air will then escape through the discharge allowing the pump to achieve full prime.
