- Selectively dissolves deposits in the sand trap via a mechanical stirring apparatus
- Process reliability ensured by use of Abrasit and stainless steel
- Low vibration and long service life with direct mounting of the stirring apparatus on the impeller
- Durable due to Ceram-coated internal surfaces of the hydraulics which enhance wear resistance

Submersible sewage pump with mechanical stirring apparatus as submersible monobloc unit for stationary and portable wet well installation.
The outlet on the pressure side is designed as horizontal flange connection. The maximum possible dry matter content is 8%, depending on the hydraulics and impeller type.
Vortex impellers are used exclusively as the impeller shape. A mechanical stirring apparatus is mounted to these as an axial extension of the motor shaft. The mixer head is made of Abrasite chilled cast iron.
Surface-cooled motors (T motors) give off their heat directly to the surrounding fluid via the housing components and can be used in immersed state for continuous duty.
The oil-filled motors (FK motors) and self-cooling dry motors (FKT, HC motors) give off their heat to the pumped fluid via a built-in heat exchanger. As a result, these motors are suitable for continuous duty either in immersed or non-immersed state.
All motors have a sealing chamber that protects the motor from fluid ingress. It can be accessed from the outside and can be monitored with an optionally sealing chamber electrode.
All filling fluids used are potentially biodegradable and environmentally safe.
The cable inlet on T, HC and FKT motors is longitudinally watertight. Up to motor size 17, cable lengths are available in fixed lengths measured in 10 m intervals. Starting from motor size 20, the cable length can be individually configured.
Fluid-side and motor-side sealing is possible in the following versions depending on the motor type:
- Version H: Mechanical seal for the fluid side, rotary shaft seal for the motor side
- Version G: Two independently-acting mechanical seals
- Version K: Block seal cartridge with two independently acting mechanical seals
