Description/construction

Ready-to-connect and fully floodable wastewater lifting unit (flood level: 2 m water column, immersion time: 7 days) with gas- and waterproof collection tank and anti-surfactor. Centrifugal pump with free-flow impeller.

DrainLift M1/8:

Single-pump unit with single-phase or three-phase electric motor for automatic operation. Switchgear with shock-proof or CEE plug, potential-free contact, integrated non-volatile alarm and adjustable follow-up time.

RV version with included check valve.

DrainLift M2/8:

Dual-pump system for automatic operation (with automatic pump changeover, standby pump mode and second pump on-off mode during peak loads). Thanks to the integrated double check valve, only one pressure line needs to be connected. Switchgear with shock-proof or CEE plug, potential-free contact, maintenance interval display and early fault detection as well as integrated volatile alarm and adjustable follow-up time.

Caution: The control unit must not be allowed to flood and must therefore be
