Supplied as complete unit ready for installation, the Multilift consist of a fully integrated collecting tank with grinder pump and submersible motor mounted on the collecting tank and a pre-wired Controller incl. a level sensor. (Non-return valves and discharge pipes are available as accessories)

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 grinder pump with Vortex impeller, submersible motor, oil chamber with physiological harmless oil filling between a mechanical cartridge shaft seal. Pump discharge with inner thread of 1 1/4 inch.

An LC221 controller with microprocessor is equipped with display for full monitoring possibilities. The pump and sensor are connected to the controller with 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.

Controller functions:

As standard, the LC 221 has 4 potential-free outputs for:
– pump running – pump failure – high water-level alarm – common fault. 6 digital inputs for the following functions:
– connecting a pressure sensor board (pre-assembled) – connecting an analogue sensor (4-20mA or 0-5V) – connecting up to four level switches or pressure switches instead of analogue sensor – connecting a separate level switch to be used for flood detection outside the Multilift. Lifting stations are often installed in a sump inside the basement - the lowest point in the building. In case of e.g. groundwater inflow or water pipe burst, an alarm will be indicated by the controller. – connecting an external alarm reset – connecting the thermal switch of the motor.

The Multilift range is designed due to the standard EN12050-1, approved and monitored by external institute LGA. Further approvals are VDE, GHOST, CB, EMV
