M.32.3.2 MULTILIFT LIFTING STATIONS 3PH

Supplied as complete unit ready for installation, the Multilift consist of a fully integrated collecting tank with pump and submersible motor, non-return valve, discharge adapter with flexible connection piece DN100 mounted on the collecting tank and a pre-wired Controller incl. a level sensor.

The fully integrated collecting tank has all necessary ports for the connection of inlet pipe, discharge pipe, vent pipe and a manually operated diaphragm pump (accessory).

The collecting tank contains 7 inlet sockets around it's shape. The back inlet DN100 is placed on a patented inlet disk to connect all inlet pipe levels (centre) between 180 and 315mm stepless. DN100 and DN50 inlet sockets on each side. DN150, DN50 sockets on the top of the tank.

Multilift corrosion free polyethylen collecting tanks are gas- and odour-proof as well as watertight , reduction of residual water and less sedimentation by chamfered bottom design.

The pump with Vortex impeller and a maintenance free submersible motor, oil chamber with physiological harmless oil filling between two shaft seals. Direction of rotation can be observed from outside over the shaft below the eye bolt.

An LC221 controller with microprocessor is equipped with display for full monitoring possibilities. The pump and sensor are connected to the controller with 4m or 10m cable and tube length. The power supply cable is 1,5m with plug (incl. phase inverter for 3 phase motor). Contactless, piezo resistive pressure sensor pluggable inside the cabinet, monitored by controller, accurate to the millimetre shown on display. Blockage free pressure tube inside the tank without movable parts inside wastewater.

The controller offer thermal motor protection and monitoring of pump operation. The thermal motor protection consists of thermal switches in the winding.
