Abstract
A grinder pump includes a pump assembly, a grinder mechanism, and a motor disposed between the grinder mechanism and the pump assembly. A shaft of the motor is operably attached at one end thereof to the grinder mechanism and at the other end thereof to the pump assembly. This arrangement enables providing smaller radial clearances between the cutting portions of the grinder mechanism. Vortex-type impeller vanes can be associated with a grinding head of the grinder mechanism to assist flow of effluent from the grinder mechanism to the pump assembly via a passageway extending about, and/or in parallel with, a motor mounting unit.
