About Us

Thompson engineers developed a series of high pressure jet pumps that can handle liquids with larger solids and more air than standard end-suction centrifugal pumps. By increasing the impeller size and adding the ENVIROPRIME Compressor-Assisted Priming System, Thompson JSC High Pressure Jet Pumps are able to pass solids up to 4-inches in size and able to prime dry and re-prime automatically. These features make the Thompson JSC Series High Pressure Jet Pumps perfect for use on a wide range of jetting, dewatering and bypassing applications.

Construction: Wellpoint installation; pilings; seawall installation; equipment wash down; dewatering excavations, canals and sumps; extended sumping
Waste Treatment: Sewer bypasses; pumping polluted hot or corrosive wastewater containing sand, mud or solids in suspension; force main pumping; dosing neutralizing liquids; pumping out settled sludge
Industry: Water jetting and blasting; piping system surcharging and pressure testing; waste pumping; flood drainage; fire fighting; recovery of hazardous liquids; transfer of neutral, acid or alkali clean or dirty liquids containing sand, mud or solids in suspension
Mining: Wash-down operations; tailings; high head/high volume applications
Marine: Barge cleaning and wash down; pile jetting; dock installation
Agriculture: Irrigation; dust abatement
Note: Alternate pump end materials available for corrosive liquids
