► Radial cutter and cutter ring: corrosion resistant
material, hardened to 55 - 60 Rockwell C.
Direction of Rotation
► Clockwise as seen from the motor rear end.
Cutting Ability Demonstration
► Specialized one single strong shaft with impeller and
radial cutter, dramatically reduces the torque requirement
on the motor, cuts with less horsepower, and increases
the pump’s efficiency. What’s more, it prevents clogging
with some troublesome objects such as sanitary napkins,
plastic, rubber, disposable diapers and cloth items.
The design of Northam grinder prevents clogging, binding CUTTING IN PROCESS
