Updated Aug 3, 2010

Thompson trash pumps are specified for the really tough jobs where a wet priming pump capable of handling large solids and/or abrasive material is needed. Thompson trash pumps outperform other centrifugal trash pumps on the market and cost less to operate. The quality and dependability engineered into each Thompson heavy duty trash pump provides the high performance you need to get the job done quickly. Each pump is factory-tested before shipping to ensure complete dependability on your project.
