Liberty’s LSG200-Series Grinder Pumps meet the demanding needs of commercial and residential sewage applications where difficult solids-handling ability is crucial. The LSG200-Series features a superior cutting system made of hardened 440 stainless steel – Rockwell C 58, for shearing solids into small particles prior to being passed to the discharge by the impeller under high pressure. Applications include individual or groups of homes, motels, schools, shopping centers, lakefront developments and systems requiring high pressure sewage pumping. Features: 2 hp, heavy-duty motor – oil filled, thermally protected; Upper and lower ball bearings; One-piece uni-body cast iron housing; 300 Series SS Rotor Shaft; 316 Stainless steel impeller; Dual seals – Upper seal is unitized durable silicon carbide. Lower seal is Viton double-lip. (Lower seal ensures that all debris is kept away from main seal); Motor windings insulated to Class B (130°C); Advanced V-Slice cutting system made of hardened 440 stainless steel – Rockwell C 58; Horizontal 1-1/4'' FNPT Discharge Back vanes on impeller and spiraled bottom plate for superior solids clearing; All stainless steel fasteners; Clog-free volute design; Designed for maximum heat dissipation and cool motor operating temperatures; Solid state starting circuit - no mechanical relay coil; 25' power cord with Quick-Disconnect; Piggy back plug with wide angle float (on automatic model) eliminates need for expensive panel
