The pump should be designed for handling raw, unscreened wastewater and storm water, with a fluid temperature range of 40°F to 100°F. The equipment should be designed for watertight operation with continuous submergence under 65 feet of water with a maximum temperature of 100°F. Key features include a centrifugal, non-clog, solids handling, submersible, wastewater type pump, with a minimum pump efficiency of 59%, and the ability to handle an 8% solid concentration. The pump should be easily removable for inspection or service, requiring no bolts, nuts, or other fastening to be disconnected. • The pump should be capable of producing 792 GPM at 72 ft. TDH. • The pump should be non-overloading throughout the entire range of operation without employing service factor. • The motor should be a squirrel cage, induction motor enclosed in a watertight housing. • The motor should be air-filled and constructed with moisture-resistant NEMA Class H insulation. • The pump should be provided with an integral motor cooling system. • The pump should be capable of passing an 8% solids consistency through the bottom of the impeller and through the sides of the impeller.
