The NIKKISO canned motor pump is an ideal solution for transfer and circulation tasks in the refrigeration industry. It can be used to pump all refrigerants including ammonia, CO2, glycol, and freons.
NIKKISO NON-SEAL pump consists of a centrifugal pump and an air-tight canned motor. Both of them are attached to each other to form one single unit, while pump and motor share one common shaft. A small flow of working fluid is forced into the rotor chamber to act as a coolant and lubricant in the motor.
