Centex Fluid Products offers Cornell Pump’s Immersible Pumps/Motors. The basic design of the immersible pump/motor is a premium efficient, inverter duty, P-Base or C-Face, totally enclosed, blower cooled motor. The design prevents water infiltration along the shaft into the motor by utilizing a triple redundant sealing system, including a patented Hydroseal design. The immersible motor can withstand up to 30 feet of submergence depth for a 2 week period.
