Vacuum- Assisted Heavy Duty Trash Pumps

PRODUCTS > Vacuum- Assisted Heavy Duty Trash Pumps

These versatile pumps are low maintenance, easy to operate and offer automatic dry priming and re-priming.

Thompson’s vacuum-assisted dry priming pump is designed with an auxiliary vacuum pump that delivers the fastest priming available and high-volume pumping of liquids and air, making it the perfect choice for high-lift applications, including liquids with abrasives or suspended solids.



As the vacuum pump rotates, the vacuum produced draws air from the centrifugal pump and suction line to automatically prime the centrifugal pump.
