SPX Johnson Fre Flow (FRE) Self Priming Pump
FreFlow pumps are self-priming centrifugal pumps suitable for handling contaminated and low-viscosity liquids. Its innovative design, eliminating the need for a non-return valve, results in less maintenance. Oil bath lubrication on the atmospheric side of the mechanical seal prevents dry running during the self priming period. The capability of handling gaseous liquids ensures smooth and continuous operation. The basic pump is available in cast iron, bronze or stainless steel. Thanks to its high-quality material, the stainless steel version is excellent for handling aggressive, corrosive and environmentally harmful liquids.
