Grundfos Pump MD.24.3.2

Supplied as complete unit ready for installation, MULTILIFT consist of a fully integrated collecting tank with two
pumps and submersible motors, non-return valve with integrated Y-branch pipe, discharge adapter with flexible
connection piece DN100 mounted on the collecting tank and a pre-wired controller including 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 8 inlet sockets.
The back inlet DN100 is placed on a patented inlet disk connecting all inlet pipe levels (centre) between 180 and
315mm stepless. There are DN100 and DN50 inlet sockets on each side and two DN150, DN50 sockets on the top of
the tank.
MULTILIFT corrosion-free polyethylen collecting tanks are gas- and odour-proof as well as watertight.
The chamfered bottom design ensures a reduction of residual water and less sedimentation.
The pump features a Vortex impeller and a maintenance free submersible motor.
The oil chamber is with physiological harmless oil filling between two shaft seals.
Direction of rotation can be observed from outside over the shaft below the eye bolt.
The LC 231 or LC 241 level controllers offer a comprehensive range of features for control and monitoring of pumps
in MULTILIFTs.
The controllers are designed for level control, monitoring and protection of Grundfos lifting stations with one or two
pumps.
An analogue level sensor is integrated into the controller and connected to the sensor tube by an air hose.
The controller is pre-set from factory to the lowest possible starting level. Adjustment to a higher starting level can be
done with the Grundfos GO app.
With the Grundfos GO app, all detailed pump settings can be easily configured, monitored and commissioned.
The display also offers the possibility to change the operating mode from auto to manual start/stop.
The controller is equipped with configurable input/output terminals.
The controller integrates seamlessly into the Grundfos range of communication modules, ensuring an easy fit into any
supervisory system such as SCADA or Grundfos CLOUD.
With the built-in motor protection, and the current measurement, the LC controller provide a service indicator function
that helps keep track of when service is needed.
The controller maintains a detailed alarm and warning log with the last 20 alerts.
The alarm log can be accessed remotely via SCADA or Grundfos CLOUD. You can also use Grundfos GO to inspect
the logs in localized, translated text for easy troubleshooting and remedial measures at the pumping station.
Configurable input/output terminals that can be used as digital input/output, analogue input.
Prevent the mains load when several pumping stations are started up at the same time with power-on delay.
