Description/design

 

Axial submersible pump as submersible monobloc unit for stationary wet installation

Hydraulics

The angle of the propeller/impeller blades can be adjusted by hand. This makes it possible to adapt the unit to use in different conditions.

Motor

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 permanent operation.

A sealing chamber 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 of the T motors is longitudinally watertight. Cable lengths can be individually configured.

Sealing

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
