Patent number: 9352327Abstract: 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 openings in the cutter plate have an unique shape which assists in the cutting of material which flows through an inlet of a grinder pump. The shape of the cutter blade cooperates with the openings in the cutter plate such that solids are forced between these respective components and thereby are efficiently cut into small pieces for passing through the openings and for discharge from the grinder pump basin system.Type: GrantFiled: June 11, 2013Date of Patent: May 31, 2016Assignee: ZOELLER PUMP COMPANY, LLCInventors: William L. Schmidt, David R. Gilbert, Bryan S. Schilling, Charles P. Carroll

Patent number: 9004381Abstract: 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.Type: GrantFiled: December 15, 2011Date of Patent: April 14, 2015Assignee: Zoeller Pump Company, LLCInventors: William L.
