DAB GRINDER15.07TEX Cast Iron High-Strength Shredder Sewage Pump for Civil Drainage with Grinder Impeller

Managing wastewater from drains in civil and commercial environments requires the high-pressure capabilities of the DAB-GRINDER15.07TEX. This submersible grinder pump is designed to handle loaded waters containing paper, textile materials and other domestic wastewater solids. By incorporating a high-strength grinding system, the unit enables the use of small-diameter piping where traditional pumps would be unsuitable. It facilitates reliable wastewater transfer in collection pits where consistent ingress requires dependable performance for property protection.

Performance is delivered by a three-phase motor operating on a 415v supply with a rated current of 2 Amps. This 0.8 kW assembly generates a maximum flow of 240 L/min and reaches a maximum head of 16.9 m. The system supports continuous S1 operation and is rated for a dry run time of up to 10 minutes. Deployment is supported by a 10-metre power cable and an IP68 protection rating for immersion depths up to 20 m across commercial building service networks.

Internal hydraulics utilize a cast iron impeller and a high-strength shredder constructed from AISI 630 stainless steel. This configuration reduces solids into a manageable slurry for transfer through small-diameter pressure pipe systems while minimizing the risk of internal blockages. Structural integrity is anchored by an AISI 431 stainless steel motor shaft and a double mechanical seal featuring silicon carbide faces in an oil chamber. These components maintain reliable hydraulic performance while preventing liquid ingress into the motor housing.

Mechanical construction consists of a GJL 200 cast iron body with a cataphoretic coating to ensure durability in aggressive submerged environments. The assembly includes thermal sensors with a 130°C threshold to safeguard the Motor insulation class F assembly. Certified to EN 12050-1, it is suitable for hazardous zones via IECEx approval. Flanged and threaded DN40 outlet connections allow for integration into civil wastewater infrastructure and high-capacity pressure pipework for efficient wastewater evacuation.
