The U-series is a 2-pole-motor-based, compact type submersible vortex pump designed for handling raw sewage, wastewater and liquid carrying solid matters and fibrous materials. Rotation of the impeller produces vortex flow in the pump casing, which allows those foreign matters to be pumped out with minimum contact to the impeller. Since this mechanism does not require the foreign matters to pass through the impeller vane, the pump offers practically unchokable pumping.

Oil Leakage Sensor TSS-TEG-08
TSS Seal Oil Sensor M8 (10m)
Externally mounted leak sensors for water detection inside of oil chamber. Please note, an additional relay e.g. finder needs to be installed.
Float switch 106-TEG-03
Float 10m (for Sewage Pumps) up to 2.2kW
Automatic Operation: Activates the submersible pump when water levels rise to a preset height and deactivates it when levels drop, preventing overflow or pump damage.
