DAB GRINDER15.11TEX Cast Iron Deep Immersion Sewage Pump for Sewage Transfer with Grinder Impeller

GJL 200 cast iron pump body construction and a heavy-duty motor housing define the DAB-GRINDER15.11TEX as a robust asset for commercial drainage. This submersible grinder pump handles wastewater containing paper, textile material and other filamentary solids where structural durability is essential in aggressive environments. It is suitable for fixed installations with a coupling device or mobile use when placed on a base directly on the tank bottom. Maintaining reliable wastewater movement is critical in building service rooms and drainage systems exposed to continual fluid ingress.

Performance is delivered by a 1.1 kW three-phase motor on a 415v supply, producing a rated current of 2.8 Amps. The pump generates a maximum flow of 320 L/min and reaches a maximum head of 24.9 m for efficient wastewater transfer. This model supports 20 starts per hour and is designed for continuous S1 duty when the motor is completely immersed. A 10-metre power cable is provided to facilitate installation in deep collection pits across commercial and industrial facilities.

Centrifugal fluid paths utilize a cast iron impeller paired with an AISI 630 stainless steel shredder system. This configuration reduces solids for transfer through small-diameter pressure pipelines while minimizing the risk of internal blockages during intensive operation. The AISI 431 stainless steel motor shaft is supported by lubricated bearings to ensure torque stability during high-load evacuation duties. A double mechanical seal featuring silicon carbide faces in an oil chamber protects the electrical assembly from liquid ingress.

The system is certified for IECEx and ATEX environments, confirming suitability for hazardous locations in commercial drainage stations. Flanged and threaded DN40 outlet connections enable seamless integration into existing wastewater infrastructure and pressure pipework. Over-temperature sensors are integrated into the windings to protect the Motor insulation class F assembly. Structural maintenance is facilitated by a constructive solution that provides quick access to the main mechanical components for onsite service.

Features

• AISI 630 stainless steel shredder system provides efficient grinding of solids for transfer through small-diameter pipes.
• AISI 431 stainless steel motor shaft is mounted on lubricated bearings for stable torque and long service life.
• Cataphoretic and acrylic coating provides a 50-micron barrier against corrosion in aggressive wastewater environments.
• Continuous S1 duty rating ensures the motor can operate indefinitely when completely immersed in the media.
• IECEx and ATEX certifications confirm compliance for operation in potentially explosive wastewater environments.
• Integrated over-temperature sensors in the windings provide a safety threshold for the Class F insulated motor.
• Flexible installation options support both mobile base-mount and fixed coupling device configurations.
