The 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, in 1" increments), and since waste is macerated BEFORE it leaves the tank, a smaller hose and overboard seacock (3/4") may be used in the discharge line.
New pump installations require #MP Hardware (tank hardware kit), ordered separately
Determine tank depth in inches, as measured from the top outside to the bottom inside
155 Series will fit the same mounting pattern used for discontinued MPT or MPS series macerator pumps
