Century-Series Centrifugal Pumps
Liquiflo’s Centry® Series are Sealed and Magnetically-Coupled (MC) Centrifugal pumps engineered and manufactured for the user with increased needs for equipment reliability. These pumps are specifically designed to handle the lower flow applications that create maintenance problems for standard ANSI pumps operating at less than BEP. The Centry Series pumps can handle flows up to 160 GPM and heads up to 100 ft. They are available in 316 Stainless Steel or Alloy-C constructions, and with threaded or flanged port configurations.
