Mode of operation

DrainLift WS 40E Basic (1~230 V) and DrainLift WS 50E Basic

The sewage produced is channelled into the pump chamber via the inlet, where it collects. When the water level reaches the switch-on level, the pump is switched on. The collected sewage is pumped into the on-site pressure pipe via the discharge pipe. When the switch-off level is reached, the pump is immediately deactivated.

DrainLift WS 40E Basic (3~400 V)

The sewage produced is channelled into the pump chamber via the inlet, where it collects. When the water level reaches the switch-on level, the pump is switched on. The collected sewage is pumped into the on-site pressure pipe via the discharge pipe. When the switch-off level is reached, the pump is deactivated after the set follow-up time.

DrainLift WS 40D Basic and DrainLift WS 50D Basic

The sewage produced is channelled into the pump chamber via the inlet, where it collects. When the water level reaches the switch-on level, the pump is switched on. The collected sewage is pumped into the on-site pressure pipe via the discharge pipe. When the switch-off level is reached, the pump is deactivated after the set follow-up time. The twin-head pump chambers also offer the following functions:

• During peak loads, both pumps are operated in parallel.
• Pump cycling is carried out after every pumping procedure.
• If one pump malfunctions, the other pump is automatically used.
