Thompson Pump’s JSC Series solids handling ENVIROPRIME pump is engineered with heavy-duty cast-iron construction and the ability to dry-prime and re-prime automatically. The portable JSC Series features pumps that range in size from 3 to 18 inches, are designed for high flows to 11,000 gallons per minute, and have maximum heads to 330 feet. These end-suction centrifugal pump ends can handle solids up to 4 inches and are available as diesel or electric driven. The ENVIROPRIME compressor-assisted dry priming system prevents blow-by, such as sewage and waste, from discharging onto the ground, making this unit more environmentally friendly.
