DAB FEKAFXV20.11TEX Cast Iron Solids Handling Sewage Pump for Wastewater Transfer with Vortex Impeller

Evacuating contaminated liquid from building lift stations is efficiently managed by the DAB-FEKAFXV20.11TEX submersible sewage pump. Certified to the EN 12050-1 standard, this unit is specialized for lifting sewage containing faecal material in commercial and residential constructions. Its robust design supports intensive service duty in aggressive environments, offering the versatility needed for both fixed installations with coupling devices and portable mobile deployment on tank bottoms.

Hydraulic output is sustained by a 1.2 kW three-phase 415v motor with a rated current of 2.9 Amps, generating a maximum head of 13 m. The pump produces a maximum flow of 570 L/Min, ensuring efficient evacuation of effluent from subsurface collection pits and wastewater holding tanks. Rated for continuous S1 operation when completely immersed, this model provides dependable performance in commercial drainage systems and civil infrastructure where stable liquid transfer is critical.

Centrifugal behavior is optimized by a vortex impeller in GJL 250 cast iron, which provides a 50 mm free passage for untreated wastewater. This configuration allows for the safe passage of solids and filamentary bodies, preventing internal clogging and reducing maintenance requirements. The discharge port configuration, supporting both DN50 flanged and 2" threaded connections, ensures the pump can be easily integrated into high-capacity commercial drainage pipework.

Construction features a GJL 200 cast iron body with a 50-micron protective coating to resist corrosion in submerged service. The motor assembly is protected by a double mechanical seal operating in an oil chamber to prevent fluid ingress and maintain long-term reliability. Safety is reinforced by winding over-temperature sensors, ensuring the internal electrical assembly remains protected during continuous S1 duty cycles in building services and wastewater transfer applications.
