Submersible sewage pump as submersible monobloc unit for stationary and portable wet well installation.
Hydraulics
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 currently used:
- Vortex impeller (W)
- Single-channel impeller (E)
Motor
Surface-cooled motors (T motor) do not have a cooling system of their own and emit their heat directly to the surrounding fluid via the housing parts. The motors can therefore be used in immersed state for continuous duty. Depending on their size, they can also be used in non-immersed state for short-time duty.
All motors have a sealing chamber that protects the motor from fluid ingress. It can be accessed from the outside and can optionally be monitored with a rod electrode. All filling fluids used are potentially biodegradable and environmentally safe.
The cable inlet is longitudinally watertight, the cable length is 10 m and the cable has free ends.
Seal
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
Ex rating
The motors have ex-approvals according to the ATEX directive.
