•The ParkUSA® Macerator Assembly is an
“In-Line Grinder” system used on
sewage systems. The unit is
recommended for gravity-flow sewer
lines which may experience high solid
concentrations that can “clog” the sewer
piping. Typical applications include
detention and correctional institutions
where vandalism is a frequent
occurrence. Inmates tend to “stuff”
sheets, towels, and shoes down toilets
to cause flooding of the building. The
macerator grinds up these solids
avoiding costly flooding and

- Pre-engineered design of the total
including vault enclosure
- Integral bypass and isolation valves
- Sump pump to avoid water damage
- Uses dual-shafted technology to
reduce solids in standard
and industrial applications
- Utilizes a 3 or 5 horsepower motor
with a 29:1 gear
- 2-Inch 4140 Steel hexagonal shafts
- Varied cutter options to optimize
- Provides protection of downstream
- Features in-line or in-channel cutter
The macerator assembly runs continuously to grind up all the
sewage that enters the system. A control panel, typically located in
a mechanical room, is the “brains” behind the grinder operation.
Solids are pulverized with rotating hardened steel teeth. In the
event an object is too hard or massive and requires multiple passes
through the grinder, the controller will reverse the grinder and
repeat the process. This sequence is performed multiple times until
the object is destroyed. If the grinder is presented with objects
which cannot be shredded after repeated tries, the controller will
shut down the grinder and trigger a service alarm.

The ParkUSA Macerator Assembly presents the main components
- Macerator Grinder Main Housing: The main housing shall be cast
from grade 65-45- 12 Ductile Iron. Unit to be equipped with
access port covers.
- Cutters: Cutters and spacers shall be arranged in a one-piece
- Seals and Bearings: The primary seals shall have elastomeric
members which operate as opposing disk springs when
compressed at the same time keeping the faces of the two metallic rings together insuring positive sealing.
- Drive and Motor: The macerator will be driven by a direct coupled
speed reducer with a 5 H.P. Immiscible, 230/460 volts
3 phase 60 hertz motor.
- Shaft Gears: Two Counter rotating shafts will be driven by two
heavy-duty spur gears hardened to a Rockwell C of 40-45.
- Electrical Controls: An Automatic Reversing Controller will be
supplied with oil tight controls and overload heater protection.
