New CHUGGER PUMP XCPSS-CI-1 X-Dry with Run Dry Protection is the first pump made by brewers for home brewers like you. Same pump as the CPSS-CI-1 but with FDA Approved Run Dry Carbon Bearing Material. ETL-certified and made with USFDA food compliant materials, it's a premium, sensible, and affordable alternative to expensive March pumps and has 25 percent more power with its 1/20 HP motor. Another benefit is stainless-steel heads that are interchangeable with existing March brand pump motors. This pump is not a self-priming pump - the CHUGGER PUMP head must be flooded with liquid prior to turning on the pump. It has been tested for safety and performance standards. Please check your electrical requirements before placing order. Must be wired by an electrician.
