ABSTRACT:
In a preferred embodiment, a single motor drives both oil and refrigerant pumps in a refrigeration chiller, the motor and oil pump being disposed in the chiller's oil supply tank and the refrigerant pump being disposed exterior thereof. The refrigerant pump pumps liquid refrigerant to the chiller's compressor section so as to cool the motor by which the compressor is driven while the oil pump pumps oil to chiller locations that require lubrication when the chiller is in operation. A uniquely designed impeller permits low pressure liquid refrigerant in its liquid state to be reliably pumped to a location of use, without significant flashing, from a source location which is at a height only a short distance above the pump inlet. A stand alone refrigerant pump embodiment is also described.
