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 air 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.
