Techneau lift pumps are designed to transport rainwater or wastewater from a low point to a high point. They ensure efficient evacuation of water to treatment or discharge points.
Dimensions
The F.E.A. or Inlet level (Fil d’Eau d’Arrivée) dimension in the pumping station is decisive in the choice of your pumping station for an underground installation outside a building.

The operating principle
1 Pump operating principle
Normal operating cycle: water rises in the tank to level 2: the ball float starts the pump. The level drops to level 1: the float stops the pump. If level 3 is reached, the alarm float (optional) triggers an audible and visual signal to warn of the risk of overflow.
2 Pump operating principle
The piezometric probe system works by measuring pressure. It is reliable and accurate. The interface on the front panel displays the station’s operating status.
Normal operating cycle: water rises in the tank and reaches level 2: the pressure sensor switches on one of the 2 pumps. The level then drops to level 1: the control box stops the pump. During the next cycle, the other pump is switched on: in this case, operation alternates.
In the event of a pump failure, the operational pump is systematically switched to level 2.
In an overflow situation, the effluent rises in the tank and reaches level 2: the pressure sensor switches on one of the two pumps. The level continues to rise and reaches level 3: the second pump is then switched on; in this case, the 2 pumps operate simultaneously.
If level 4 is reached, the alarm float switches on the 2 pumps and an audible and visual signal warns of the risk of overflow. The 2 pumps are then stopped by the alarm float.
