Self-priming centrifugal pumps for various applications
SPX Johnson Pumps has many years experience in designing, manufacturing, and servicing of self-priming centrifugal pumps. FreFlow pumps are self-priming centrifugal pumps for handling contaminated low viscosity liquids.
An innovative design eliminates the need for a non–return valve resulting in reduced maintenance and safe operation during suction. Standard applications are covered by cast-iron or bronze while stainless steel allows operation with contaminated, corrosive and environmentally harmful liquids. The unique design of the housing and impeller is best suited to handle solid containing liquids.
A wide variety of pump drives is available to suit all customer and application needs. The combination of its reliable operation and easy maintenance makes the FreFlow a suitable pumping solution for a large number of applications.
