Grundfos MDV.80.80.75.2.51D /450.SL (97577840)
Supplied as complete unit ready for installation, MULTILIFT consist of a compact wastewater lifting station with one or two 450 litre collecting tanks, two horizontal submersible sewage pumps of the SE range, controller including analogue level sensor and connection accessories.
The 450 liter tank is made of airtight, corrosion-free polyethylene and is completely gas- and odour-proof. The tank is supplied with the following:
|
The tank is designed with an inner patented chamfer and suction bends to avoid sedimentation and to reduce residual water. In case of additional collecting tank, 4 connection sockets DN150 are placed at the sides.
Horizontal sewage pumps are equipped with a single channel impeller or Vortex impeller. Moreover, these sewage pumps offer:
|
Isolating valves, non-return valves, discharge pipes, a manually operated diaphragm pump, bolts and gaskets as well as a third 450-litre tank are available as accessories.
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.

Applications
- Commercial wastewater — Commercial buildings have vastly different requirements for wastewater transfer. Grundfos supplies wastewater pumps and lift station pumps ensure superior reliability and safety, as well as high efficiency.
- Domestic wastewater — With a series of optimised drainage pump systems, lifting stations and sump pumps, you can gain full control of domestic wastewater.
- Wastewater transport — When continuously transporting wastewater, you need reliable and optimised solutions for wastewater pumping stations and networks. Better system design, for example by using CFD simulations, tackles hydraulic issues in advance, reduces downtime and minimises risk.
