Oberdorfer Macerator Pump w/Vacuum Switch 25 GPM # 406MK-7N26 (CC)

Oberdorfer, macerator, single phase, close-coupled, bronze, self priming, rubber impeller pump with vacuum switch. Designed specifically for pumping sewage from boats to holding tanks or sewer connections. The function of the pump is to suction the solids and liquids from the holding tanks, grind the effluent with the rotating cutter head down to a small particle size and discharge of the waste to a convenient receptacle either above or below the pump elevation. Macerator pumps are not designed to be run dry of liquids. The impellers will wear and the pumps capacity to discharge the liquids will be lessened. The Oberdorfer macerator pump will macerate and pump all waste and tissue normally found in marine waste systems. IT WILL NOT HANDLE HARD SOLID OBJECTS, SANITARY NAPKINS, OR RAGS.
