Description/construction

Submersible pump for stationary and portable wet well installation for fully automatic operation, thanks to float switch installation.

Hydraulic section

The pumps are equipped with an open multi-vane impeller and have a free outlet of 10 mm. The discharge connection is a vertical threaded connection.

Electric motor

Single-phase electric motor with cooling jacket and integrated running capacitor. The motor heat is given off directly to the pumped fluid via the motor housing.

The motor is equipped with an automatic motor winding temperature sensor. This means that the motor stops on overheating and restarts automatically after cooling down.

Sealing

On the fluid side there is a mechanical seal, on the motor side a rotary shaft seal. Between the seals there is a sealing chamber filled with white oil.

Cable

The pump is equipped with a 10 m power supply cable with plug with protective contact and an attached float switch.

Versions:

Drain TSW with vortex function - The vortex function provides continuous vortex creation in the suction area of the pump. This prevents sediment from sinking and settling. This prevents contamination of the sump bottom and reduces the formation of unpleasant odors
