Submersible sewage pump as submersible monobloc unit for stationary wet well and dry 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.
The following impeller shapes are used:
- Two-channel impeller (Z)
- Three-channel impeller (D)
- Four-channel impeller (V)
Each multi-channel hydraulic unit (Z, D, V) is equipped with a mobile and stationary wear ring. These contribute long-term to ensuring the uniform efficiency of the unit.
Dry 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. Depending on the size, they can also be used in non-immersed state for short-term or continuous duty.
The oil-filled motors (FK motors) and self-cooling dry motors (FKT motors) give off their heat to the pumped fluid via a built-in heat exchanger. Therefore, these motors are suitable for continuous duty in immersed and non-immersed condition or for dry well installation.
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 optional sealing chamber electrode.
All filling fluids used are potentially biodegradable and environmentally safe.
The cable inlet on the T and FKT motors is longitudinally watertight. Cable lengths can be individually configured.
Fluid-side and motor-side sealing is possible in the following versions depending on the motor type:
- Version G: Two independently operating mechanical seals
- Version K: Block seal cartridge with two independently operating mechanical seals
