FGb / FGa — Vortex Sewage Pumps
Submersible vortex pumps for domestic, municipal and industrial wastewater transfer. They handle liquids containing solids, fibrous material and sludge. FGb uses curved vanes, while FGa uses straight vanes, with different hydraulic ranges.
Values describe series limits and may not occur at the same duty point. Final selection requires the manufacturer curve, fluid and motor configuration.
