Overview

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

Type

Sewage lifting unit as a single or dual pump system

Application

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).

Equipment/function

Fully flooded sewage lifting unit (ready for connection), incl. control unit and the following components:
Motor winding temperature control sensor
Voltage free contact for generalized fault indication (SSM) and tank overflow alarm
Nonvolatile alarm
Level control by means of a float switch
Detachable pump cable
Non return valve
Sealing for the inflow line
Circular saw for the air inlet
Hose connection for venting
Hose connection for hand membrane pump
Pressure pipe connection kit
Fixing material
Insulating material

Description/construction

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.
