Description/construction

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 used:

  • Vortex impeller (W)
  • Single-channel impeller (E)

Depending on type, single-channel hydraulic systems can be equipped with an impeller wear ring and/or a casing wear ring made of hardened material. These contribute long-term to ensuring the uniform efficiency of the unit.

Motor

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.

A sealing chamber 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 dry motors is longitudinally watertight, cable lengths can be individually configured.

Seal

Fluid-side and motor-side sealing is possible in the following versions depending on the motor type:

  • Version G: Two independently-acting mechanical seals
  • Version K: Block seal cartridge with two independently acting mechanical seals
