Casing: Volute design for high efficiency. Close grained cast iron for high strength. Accurately machined to assure uniform impeller clearance , and rigid permanent alignment with the hanger pipe.
Shaft: Steel, cold finished, high tensile strength, turned, ground and polished, of ample diameter for maximum speed operation without vibration. The shaft is provided with a micrometer adjustment at the thrust bearing to permit proper centering of impeller in casing.
Bearings: A heavy duty grease lubricated ball thrust bearing, elevated above the pump support plate, mounted in a dust and moisture proof housing located in the motor pedestal, supports the impeller, shaft , and flexible coupling weight. Bronze lower and intermediate guide bearings are spaced to restrain shaft deflection thereby eliminating vibration.
Impeller: a semi closed one piece two-vane bronze impeller, with pump-out vanes on the back shroud, dynamically balanced, reduces back pressure on the lower bearing and permits long life, and efficient operation.
Support Leg: Made of seamless steel pipe to maintain accurate alignment of pump bearings, and serve as a rigid support for pump casing.
Discharge Pipe: 2" heavy seamless steel pipe supported at the floor plate and furnished with an expansion fitting at the casing connection to eliminate piping strain on the pump.
Floor Plate: A heavy fabricated steel pump support plate is furnished to permit sump pump installation or removal without disturbing other equipment mounted on the cover.
Control: An integral float switch assembly actuated by a large heavy gauge copper float makes positive contact.
Motor: Of well known motor manufacturers standard NEMA construction are furnished and are selected for quiet operation. Motors are connected by a flexible coupling and are mounted on a one piece cast iron support pedestal which is machined to maintain perfect alignment between the pump and motor shaft.
