Automatic priming pump

Thompson Pumps 4JSCG Enviroprime Pump is a high head four-inch automatic priming centrifugal pump that provides flows of up to 1,300 gallons per minute and heads up to 330 feet. The pump handles solids up to three inches and is ideal for sewer by-pass pumping and abrasive applications, emergency flood response, and any other applications that require the transfer of liquids that contain solids. The Enviroprime priming system, unlike most automatic priming systems, prevents product blow-by of pumpage, such as sewage, effluent and waste, from being discharged onto the ground or through hoses that carry the pumpage back to the source, making it environmental friendly. A combination of durable construction and highly efficient pump ends provide longer life and economical operations, and most importantly, lower fuel costs.
