Construction
DrainLift BOX-32 ... and DrainLift BOX-32 ... D ...
Gas-tight and watertight collection reservoir made from plastic, with deposit-free interior. Two DN 100 connections at a 180° angle to each other for the inlet as well as venting and cable routing. The discharge connection is located at a 90° angle to the other two connections. For easy maintenance of the unit, the cover serves as an inspection opening.
Sewage pump with integrated turbulator (twister function), open multi-channel impeller and vertical threaded connection. Pump housing, strainer and impeller made of composite material. 1~ motor (jacket cooling) with integrated operating capacitor and self-switching thermal motor monitoring. Stainless steel motor housing. Oil-filled sealing chamber with double sealing: a rotary shaft seal is installed on the motor side, a mechanical seal on the pump side. Connection cable with float switch and fitted plug (CEE 7/7).
The twister function guarantees permanent turbulence within the pump's intake area. The turbulence prevents the settling sediments from sinking and settling. This ensures a clean pump sump and reduces the build-up of odours.
The level control takes place via the float switch attached to the pump. The “pump on/off” switching level is determined by the cable length of the float switch.

The level control takes place via the separate float switch in the tank and a switchgear. The switchgear is preset. The “pump on” switching point is determined by the cable length of the float switch. The “pump off” switching point is defined by the set follow-up time in the switchgear. The switchgear offers the following functions:
- Collective fault signal (SSM)
- High water alarm – additional float switch available as an accessory
- Integrated buzzer, mains-independent – 9 V rechargeable battery included in the scope of delivery
