Waste Macerator Pumps
155 Series SweetTank™ Compatible

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.

How To Order

Determine tank depth in inches,
as measured from the top outside
to the bottom inside.

Order STP-XX-Voltage.
(XX = tank depth)
or
155-61XX-YY
(XX = tank depth)
(YY = voltage)


New pump installations require GROCO® #MP Hardware (tank hardware kit), ordered separately.

155 Series will fit the same mounting used for discontinued MPT or MPS Series macerator pumps.
