NIKKISO COLDFLO®
Canned Motor Chiller Pumps


Features:

  • Sealless Leakproof Design.
  • Corrosion Resistant Materials.
  • Compact Configuration.
  • Close Coupled Motor.
  • Heads to 60 feet.
  • Flows to 300 GPM.
  • Low NPSH Configuration.


    The NIKKISO COLDFLO is a canned motor chiller pump designed for sealless, leakproof operation. Utilizing state-of-the-art pump technology, it features maximum hydraulic and electrical efficiency. These technological improvements directly translate to improved chiller capacity and efficiency. As an additional benefit, they also increase pump reliability and reduce wear resulting in unprecedented runtime availability and Mean Time Between Preventative Maintenance (MTBPM) well above industry standards.

    The COLDFLO’s unique high efficiency inducer design assures low inlet loss, cavitation reduction, and successful long term operation even in installations with the minimal NPSH availability typical of refrigeration systems.

    Because of its sealless design, it is well suited for circulating and transferring the most aggressive heat transfer fluids in environmentally sensitive areas or locations with critical contamination concerns like Beverage, Biotechnology, Food, Medical and Pharmaceutical facilities.


    Typical COLDFLO Installations:

  • Ammonia Circulation Systems
  • CFC / HFC Circulation Systems
  • Brine Circulation Systems
