Stenner™ pumps are designed and built for reliable performance, offering the capability of output ranges of 0.06 oz. per day to 170 gallons per day. The pumps offer the advantage of using a pump tube material that handles a variety of chemicals, muriatic acid (31.45%), sodium bisulfate and sodium hypochlorite (15%) approved chemicals. Component life can be prolonged by always rinsing off and wiping chemicals, residue and debris from the tube housing and roller assembly before replacing the pump tube. A special grease can also be purchased (part# MAGCSGR), so the pump can be properly lubricated when disassembling and reassembling.
