Description/construction

Fully submersible sewage lifting unit, ready for connection (flooding height: 2 mWS, overflow time: 7 days) with a gas and watertight collection tank equipped with buoyancy safeguards. Centrifugal pump with vortex impeller.

DrainLift M1/8:

Single-pump system with single-phase or three-phase AC motor for automatic operation. Switchgear with shock-proof or CEE plug, potential-free contact, integrated and mains-independent alarm and adjustable follow-up time.

RV version with non-return valve included in the scope of delivery.

DrainLift M2/8:

Double-pump system for automatic operation (with automatic duty cycling, standby and peak-load operation). Due to the integrated double non-return valve, only one pressure pipe connection is required. Switchgear with shock-proof or CEE plug, potential-free contact, maintenance interval display, early fault detection and integrated and mains-independent alarm and adjustable follow-up time.

Attention: The switchgear is not submersible and must therefore be arranged in such a way that it is overflow-proof.
