Description/construction

Fully submersible sewage lifting unit, ready for connection (flooding height: 2 mWS, overflow time: 7 days) with a collection tank that is impermeable to gas and water and that is equipped with a buoyancy safeguard.

RexaLift FIT L1:

Single-pump system with three-phase motor, switchgear for automatic operation, CEE plug, potential-free contact for collective fault signal, integrated and mains-independent alarm and adjustable follow-up time.

RexaLift FIT L2:

Double-pump system with three-phase motor, switchgear for automatic operation (with automatic switch, reserve and peak-load operation), CEE plug, potential-free contact for collective fault signal, integrated and mains-independent alarm and adjustable follow-up time. Only one pressure pipe connection is required due to an integrated double non-return valve.

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