JSV Series Pumps

PRODUCTS > JSV Series Pumps

The JSV series centrifugal pumps provide automatic self-priming and large solids handling.

The durable construction and highly efficient designs provide longer life, economical operations and lower fuel costs.

Thompson Pump’s exclusive OVT (oil-less vacuum technology) dry priming pump provides 97 cfm for rapid priming and includes the exclusive Enviroprime System® that eliminates product blow-by. The OVT is a multi-purpose pump that can be used on most construction sites. The centrifugal pump end is designed with efficiency in mind for improved fuel economy and the ductile iron components add a longer life.



As the claws of the oil-less vacuum pump rotate, the vacuum produced draws air from the centrifugal pump and suction line to automatically prime the centrifugal pump. The Enviroprime System® chamber connected to the suction of the pump directs the air to the oil-less vacuum pump and prevents any fluid from entering the oil-less vacuum pump or discharging onto the ground.


  • Flows up to 10,500 gpm
  • Discharge heads up to 340 feet
  • Suction lift up to 28 feet
  • Solids handling up to 4 inches
  • Uses exclusive Enviroprime System® offering fully automatic priming and re-priming and eliminates blow-by during operation
  • Oil-less vacuum technology (OVT) offers 97 cfm
  • Abrasive resistant tungsten carbide vs. silicon carbide run dry mechanical seal with Viton elastomers
  • No-contact rotors in vacuum pump eliminates premature wear for long life and performance
  • Enclosed impeller for improved efficiency (self-cleaning open impeller option available)
  • CD4MCu stainless steel option available
  • 12-month limited warranty covers manufacturing defects in materials and workmanship

Recon Telemetry System
Pump is operated and monitored through cellular, satellite and Wi-Fi, allowing access to pump metrics, the ability to pull reports, and to set alarms through a digital dashboard.

Silent Knight®
Sound-attenuated canopy reduces pump sound levels to or below 69 dBA. Fully insulated, weather-proof and lockable, the Arctic Night® variation is ideal for extremely cold temperatures.

Self-Cleaning Impeller
Serrated wear plate shreds apart stringy materials, preventing ragging and reducing pump clogging. Significantly decreases pump maintenance time. Ideal for sewer bypass.
