Fristam centrifugal pumps FPC Superior pumping performance for gaseous liquids. These new self- priming pumps combine Fristam's proven impeller with a rotor screw. This clever design results in a low-noise hybrid that pumps liquids with significant gas content at high efficiency. The FPC is particularly Gasket material Mechanical seal Mechanical seal materials Centrifugal pump with upstream rotor screw for pumping gaseous liquids of low to medium The eccentrically arranged rotor casing, recirculation pipe and rotor screw allow easy transportation of gaseous liquids. The FPC's construction follows...
