Self-Priming Pumps
FreFlow - Sensible Alternative to Submersible Pumps
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. The self-priming ability prevents the pump from running dry, and ensures smooth and easy operation.
Especially suitable for contaminated liquids, as well liquids containing air or gas, for sumps, gullies and many other applications where a suction lift is required.
