Wilo-RexaLift FIT L


Low system weight for easy installation
Built-in non-return valve
Flexibility due to free choice of connection point of the supply line
Operational reliability due to integrated thermal motor protection and network-independent alarms for generalized fault signal (SSM) and tank overflow


Sewage lifting unit as a single or dual pump system


Pumping wastewater with faecal matter (in accordance with DIN EN 12050-1) that cannot be piped to the sewer system through the use of natural inclines, and disposal of fluids with backflow protection from discharge points below the backflow level (in accordance with DIN EN 12056-1).

Ready-to-connect and fully floodable sewage lifting unit (flood level: 2 m water column, immersion time: 7 days) with gas- and watertight accumulation tank and backflow preventer.

RexaLift FIT L1:

Single-pump unit with three-phase electric motor, control unit for automatic operation, with CEE plug, potential-free contact for generalized fault alarm, built-in non-volatile alarm and configurable shutdown delay time.

RexaLift FIT L2:

Two-pump unit with three-phase electric motor, control unit for automatic operation (with automatic changeover from standby to peak mode), with CEE plug, potential-free contact for generalized fault alarm, built-in non-volatile alarm and configurable shutdown delay time. Due to the built-in double check valve, only one pressure line needs to be connected.

Warning: The control unit must not be allowed to flood and must therefore be installed in a watertight place.
