DAB GRINDER15.15TEX Cast Iron EN 12050-1 Certified Sewage Pump for Effluent Handling with Grinder Impeller

Internal fluid velocity paths and hydraulic configuration in the DAB-GRINDER15.15TEX are optimized for high-pressure wastewater transfer. This cast iron unit manages contaminated liquids where consistent volumetric movement is required for property protection in commercial building services. Maintaining steady flow behaviour during continuous S1 duty is essential for infrastructure protection in drainage rooms and lift stations. It provides a durable solution for handling wastewater containing filamentary solids at temperatures up to 50°C.

Performance is delivered by a 1.6 kW three-phase motor on a 415v supply with a rated current of 3.8 Amps. The pump achieves a maximum flow of 320 L/min and reaches a maximum head of 27.3 m. Deployment is supported by a 10-metre power cable and an IP68 protection rating for immersion depths up to 20 m. Thermal sensors are integrated into the windings with a 130°C threshold for Motor insulation class F protection. This configuration helps safeguard the motor during intensive wastewater handling cycles.

Centrifugal hydraulics utilize a cast iron impeller and an AISI 630 shredder to reduce solids into a fine slurry suitable for transfer through small-diameter pressure pipelines. This design provides significant clog resistance during intensive service and minimizes the risk of internal blockages. Structural integrity is supported by an AISI 304 stainless steel motor shaft and double mechanical seals featuring silicon carbide faces in an oil chamber. These components maintain hydraulic performance while preventing liquid ingress into the internal assembly during demanding operating conditions.

Mechanical construction consists of a GJL 200 cast iron body with a cataphoretic coating for long-term wear resistance. The pump is certified to EN 12050-1 and meets IECEx standards for hazardous locations in commercial complexes. Flanged and threaded DN40 outlet connections allow for integration into wastewater infrastructure and pressure pipework. Its constructive solution provides easy access to all main mechanical components, facilitating rapid onsite maintenance and reducing downtime.
