DAB FEKAFXC20.11TEX Cast Iron IECEx Approved Sewage Pump for Effluent Handling with Channel Impeller

Internal fluid velocity paths and hydraulic configuration in the DAB-FEKAFXC20.11TEX are optimized for the high-capacity transfer of sewage water and groundwater. This cast iron unit manages contaminated liquids where consistent volumetric movement is required for property protection in commercial building service. Maintaining steady flow behavior during continuous S1 duty is necessary for infrastructure protection and facility maintenance in rooms subject to flooding. It provides a durable solution for drainage stations processing waste water without fibers at temperatures up to 50°C.

Technical capacity is provided by a 1.0 kW three-phase motor operating on a 415v supply with a rated current of 2.6 Amps. The pump achieves a maximum flow of 720 L/min and reaches a maximum head of 12.4 m to satisfy specific site discharge requirements in building service environments. Deployment in subsurface collection pits is supported by the 10-metre 07RN8-F power cable and an IP68 protection rating for depths up to 20 m. Over-temperature sensors are integrated into the motor windings with a 130°C threshold to protect the Motor insulation class F assembly.

Centrifugal hydraulics utilize a cast iron channel impeller with an anti-lock system to facilitate a 50 mm free passage of suspended solids. This specialized design provides significant clog resistance and ensures reliable wastewater transfer during intensive service in commercial complexes. Structural integrity is supported by an AISI 431 stainless steel motor shaft and double mechanical seals featuring silicon carbide faces. These components work in unison to maintain volumetric efficiency while preventing liquid ingress into the oil chamber during high-load evacuation duties.

Mechanical construction consists of a GJL 200 cast iron body with a cataphoretic coating to ensure durability in aggressive submerged environments. The pump is certified according to EN 12050-2 and meets IECEx and ATEX standards for safe operation in hazardous locations within commercial drainage networks. Its constructive solution provides easy access to the main mechanical components, facilitating rapid onsite maintenance and reducing potential downtime. Standard DN50 discharge connections allow for standardized integration into civil wastewater infrastructure and high-capacity pipework.
