JSC ENVIROPRIME SYSTEM® SERIES PUMPS
The JSC series centrifugal pumps provide automatic self-priming, large solids handling up to 3 inches and feature the exclusive Thompson Pump Enviroprime System®.
These compressor-assisted pumps lead the industry in sewer bypass, emergency response and any high-head/high-volume applications. Heavy-duty, dry-priming with auto-start and compact design options make this pump the ideal solution for most jobs.
WORKING PRINCIPLE
The JSC’s Enviroprime System® uses an air compressor to separate air from water, which keeps the pump’s venturi from clogging. An air compressor supplies air to a venturi, providing powerful suction to the chamber located at the pump inlet. The chamber empties air from the pump’s suction line causing it to fill with water. When the suction line is fully primed, an internal float rises in the Enviroprime System® chamber, shutting off the air suction.

OPTIONS
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.
