Product details
The WFB design separates air from recirculating liquid in its priming chamber. An electrically controlled air valve closes during startup and opens after stopping to interrupt siphoning and retain the liquid needed for the next start. The initial filling procedure and available suction conditions must be confirmed before commissioning.
The sealing arrangement combines an auxiliary-impeller hydrodynamic seal with a stationary sealing function. This construction is different from selecting a conventional end-suction pump solely by its flange sizes. The same 50WFB-A curve also lists 7.5 m³/h at 28 m and 15 m³/h at 24.5 m; these are alternative operating points, not simultaneous maximum ratings.
SELECTION NOTES
Specify the operating duty
Specify liquid composition, temperature, density, static suction lift, suction-pipe losses and start frequency. Confirm initial fill, air-valve control, wetted materials and seal compatibility.
Published limits may describe different configurations within a series. Confirm that the required operating conditions are valid together.
