Boat pump 155 Series

granulatortoiletelectric

155 Series waste macerator pumps make fast work (17 GPM) of holding tank pump-out. Sizes are available to fit any rigid holding tank (36" maximum depth, 1" inch increments), and since waste is macerated BEFORE it leaves the tank, smaller hose and overboard seacock (3/4") may be used in the discharge line. NOTE: New pump installations require GROCO # MP Hardware (tank hardware kit), ordered separately.
