Canned Motor Pumps (Model HCR)

Can-O-Matic Pumps
Reliable Zero Leakage Pumps - Many Applications, One Pump

Standard Features

Hermetically sealed for use when the possibility of leakage is unacceptable. The Can-O-Matic uses an ANSI pump end with a back pull out design which makes it readily suitable for retro fit with out costly re-piping. The Can-O-Matic features conical or tapered segmented bearings (for larger motors with greater radial loads) which are ideal for liquids with low lubricity and/or low viscosity. The bearings are spring loaded to maintain concentricity and compensate for wear. Axial and radial thrust loads are balanced by Buffalo Pumps’s patented Thrust-O-Matic device. This combined with low NPSH required characteristics results in low maintenance and service.
