DAB FEKAFXC20.22TEX Cast Iron IECEx Approved Sewage Pump for Sewage Transfer with Channel Impeller

Heavy-duty housing casting and rigid structural foundations define the DAB-FEKAFXC20.22TEX as a robust asset for commercial drainage infrastructure. This assembly is built for intensive duty in subsurface collection pits, handling contaminated fluids and sewage water within a supported liquid temperature range of up to 50°C. Maintaining material integrity is essential for building service rooms and large-scale lift stations prone to significant debris and high fluid ingress. It provides a reliable solution for high-volume liquid movement where performance must remain stable across aggressive demands.

Hydraulic performance is provided by a 2.2 kW three-phase motor on a 415v supply, producing a rated current of 4.9 Amps. The pump generates a maximum flow of 960 L/min and reaches a maximum head of 19.1 m for the efficient evacuation of sewage water and groundwater. The system is rated for continuous S1 operation and can withstand dry running for up to 10 minutes without damage to the internal assembly. Power is distributed through a 10-metre 07RN8-F cable to facilitate installation in deep collection pits and large-scale subsurface infrastructure across commercial networks.

Internal centrifugal pathways utilize a cast iron channel impeller with an anti-lock system to facilitate a 50 mm free passage of suspended solids. This specialized hydraulic configuration offers high efficiency and significantly reduces the risk of blockages during intensive evacuation cycles in building services. By enabling large suspended particles to move freely through the housing, the unit maintains its volumetric throughput throughout its service life. The motor shaft is constructed from AISI 304 stainless steel, supported by double mechanical seals featuring silicon carbide faces in an oil chamber.

Mechanical construction includes an IP68 protection rating for immersion up to 20 m deep and a cataphoretic coating for enhanced corrosion resistance. Motor protection is supported by thermal sensors in the windings with an intervention threshold of 130°C to safeguard the Motor insulation class F assembly from heat-related wear. Standardized DN50 discharge connections ensure compatibility with standardized building wastewater pipework and high-capacity drainage systems. The constructive solution provides easy access to the main mechanical components, facilitating rapid and simplified onsite maintenance.
