Abstract

A motor-pump combination for pumping dielectric coolants is provided which eliminates coolant leakage, has ease of maintenance, small size and reliability. Pump-motor assembly 10 is suspended from top cover plate 12 and installed in dielectric liquid container 14 which could be the system expansion tank. Pump 16 is pluggable, i.e., it may be installed or more importantly replaced without breaking any fluid lines. No discharge or suction shutoff valves are required. Pump discharge pipe 18 is directed downward and engages discharge line 20 which may be part of tank 14. An Oring (or other conventional seal) is used to seal between pump discharge pipe 18 and discharge line 20. The suction side of pump 16 has no piping connection whatsoever, since it is immersed in the dielectric liquid 22 within the container.

Modular Immersed Dielectric Pump

A motor-pump combination for pumping dielectric coolants is provided which eliminates coolant leakage, has ease of maintenance, small size and reliability. Pump-motor assembly 10 is suspended from top cover plate 12 and installed in dielectric liquid container 14 which could be the system expansion tank. Pump 16 is pluggable, i.e., it may be installed or more importantly replaced without breaking any fluid lines. No discharge or suction shutoff valves are required. Pump discharge pipe 18 is directed downward and engages discharge line 20 which may be part of tank 14. An Oring (or other conventional seal) is used to seal between pump discharge pipe 18 and discharge line 20. The suction side of pump 16 has no piping connection whatsoever, since it is immersed in the dielectric liquid 22 within the container. Cover plate 12 to which motor-pump combination 10 is attached is of the quick release type so that the cover and motor-pump combination 10 can be quickly disconnected from the system by merely removing the cover. The removal automatically breaks discharge line 20. It will be appreciated that there is no coolant leakage since there are no rotating liquid seals, valves, etc.
