DAB GRINDER15.22TEX Cast Iron IECEx Approved Sewage Pump for Wastewater Management with Grinder Impeller

High-pressure wastewater transfer in commercial and civil drainage systems requires reliable grinding performance, making the DAB-GRINDER15.22TEX suitable for demanding lift station and collection pit applications. This cast iron unit handles contaminated wastewater in large complexes while supporting efficient transfer through small-diameter pressure pipe systems. The heavy-duty construction facilitates permanent submerged service while maintaining dependable hydraulic performance in environments subject to continual fluid ingress.

Performance is delivered by a 2.1 kW three-phase motor on a 415v supply with a rated current of 4.7 Amps. The system achieves a maximum flow of 320 L/min and reaches a maximum head of 32.8 m for high-pressure wastewater evacuation. This model is certified for continuous S1 operation and up to 20 starts per hour. Power is distributed through a 10-metre power cable to facilitate deployment in subsurface wastewater handling pits and collection stations across commercial and industrial facilities.

Internal centrifugal pathways utilize a cast iron impeller with an AISI 630 shredder to reduce paper, textile material and other solids into a manageable slurry. This hydraulic configuration supports reliable wastewater transfer through small-diameter pipework while minimizing the risk of internal blockages. The AISI 304 motor shaft is supported by lubricated bearings and a double mechanical shaft seal featuring silicon carbide faces in an oil chamber. These components ensure the internal electrical assembly remains protected from liquid ingress throughout its service life.

Mechanical integrity is reinforced by a GJL 200 cast iron body with an IP68 protection rating for depths up to 20 m. The assembly includes thermal sensors with an intervention point of 130°C for proactive protection of the Motor insulation class F assembly. It is certified for IECEx and ATEX hazardous zones, ensuring compliance with safety standards for commercial wastewater systems. Flanged and threaded DN40 outlet connections allow for integration into pressure drainage systems and standardized wastewater infrastructure.
