Grinder pump basin system

摘要

A grinder pump basin system is provided which includes a basin; a cover plate; a bracket secured to the cover plate; and a grinder pump with cutter plate with openings and a cutter blade secured to the bracket above a bottom surface of the basin. The bracket includes a front portion, which prevents waste water from interacting adversely with the grinder pump when it enters the basin. A discharge system for the grinder pump is secured to an outlet of the grinder pump and includes a discharge pipe and a flexible discharge coupling. Flow directional jets are also provided in an elbow of the pump discharge system to direct waste water and solids away from the grinder pump.
