DAB FEKAFXC20.15MEX Cast Iron IECEx Approved Sewage Pump for Wastewater Handling with Channel Impeller

Efficiency optimization and long-term operating cost scaling are central to the design of the DAB-FEKAFXC20.15MEX in commercial building service. This cast iron unit handles rainwater and sewage water in large complexes, supporting the efficient removal of groundwater from below ground levels. The heavy-duty construction facilitates permanent submerged service while maintaining high volumetric throughput in drainage rooms subject to persistent flooding. It provides a reliable asset for facility management where consistent effluent handling is required across varying liquid levels and demands.

Performance is delivered by a 1.5 kW single-phase asynchronous motor operating on a 240v supply with a rated current of 9.1 Amps. The system achieves a maximum flow of 840 L/min and reaches a maximum head of 15.3 m for high-load evacuation in subsurface collection pits. This model features an integrated capacitor and is certified for continuous S1 operation when fully immersed in the media. Power is distributed through a 10-metre power cable to facilitate deployment in subsurface wastewater handling pits and collection stations prone to high fluid ingress and flooding events.

Internal centrifugal pathways utilize a cast iron channel impeller with an anti-lock system to facilitate the passage of solids up to 50 mm without contact. This hydraulic configuration ensures high efficiency and reliable wastewater transfer, reducing the risk of internal blockages during continuous duty in large building networks. The motor shaft is supported by lubricated bearings and a double mechanical shaft seal featuring silicon carbide faces in an oil chamber. This setup ensures the internal electrical assembly remains shielded from liquid ingress throughout its service life in contaminated fluids.

Mechanical integrity is reinforced by a GJL 200 cast iron body and motor housing with an IP68 protection rating for immersion depths up to 20 m. The assembly includes over-temperature sensors in the motor windings with an intervention point of 130°C for proactive motor protection during intensive duty cycles. It is certified for IECEx and ATEX hazardous zones, ensuring compliance with safety standards for commercial drainage infrastructure. Standardized DN50 discharge connections ensure compatibility with high-capacity building wastewater pipework and standardized civil drainage systems.
