ABSTRACT:
A pump which is designed to be mounted within a recirculating water system where a portion of the recirculating water is diverted and caused to flow through the pump with this recirculating water to absorb heat that is produced during the operation of the motor. The heated diverted water is then added back to the recirculating water system. The pump includes an electric motor which is mounted within a motor housing and is completely enclosed therein. An electrically insulative mounting arrangement mounts the motor relative to the motor housing preventing the conductance of electricity therebetween. The motor housing is filled with oil thereby submerging of the electric motor in oil. The motor housing is enclosed within a seal plate. Surrounding the motor housing is an annular chamber through which the liquid is caused to flow. A baffle arrangement is located within the annular chamber to direct the flow of the liquid so that all area across the surface of the pump housing has liquid flowing thereacross. The heat that is produced in the operation of the motor is absorbed by the oil which in turn is conducted through the motor housing to be absorbed by the diverted liquid prior to being added back into the recirculating liquid system. The impeller is mounted in conjunction with a wear ring which functions to properly align the impeller.
