The C-O-M "R" is the PUMP of CHOICE for refrigerant applications.

Design Features

The C-O-M "R" is a hermetically sealed, zero leakage pump designed specifically for the refrigeration industry. The C-O-M "R" eliminates the inherent maintenance and leakage problems associated with mechanical seals. It uses an ANSI standard pump end with a back pull out design for easy maintenance. The motor is liquid cooled with unique conical, self lubricating, spring loaded bearings that are self compensated for wear. Axial and radial thrust loads are balanced by Buffalo Pumps’s patented Thrust-OMatic device. Impellers for the C-O-M "R" are designed to provide low NPSH required characteristics. In fact almost all applications can be met with as little as 3 feet of NPSH available or less.
