Function and Principle
Description
Flap Valve: Facilitates flow into the pump, seals vacuum in the pipes and prevents backflow.
Macerator: The macerator grinds any solids to a fine pulp.
Helical Screw: The helical screw uses liquid to create a seal facilitating vacuum in the pump housing.
Shaft: The shaft is the connecting factor between the macerator, helical screw and motor. It supports and rotates the helical screw and macerator.
Motor: Supplies power to support pump function.
Fan: The fan provides cooling for the motor.
Inlet: Flow inlet from the source into the pump.
Outlet: Flow outlet from the pump to the pipe connection/discharge.
