Grundfos EF30.50 .11.E.Ex.2.50B (96878447)
GRUNDFOS EF AUTOADAPT pump is a portable pump for both domestic and industrial applications.
The pump has a single-vane, semi-open impeller for 30 mm free passage and is suitable for pumping
|
The compact design makes the pump suitable for both temporary and permanent installation.
The pump is a cast iron submersible pump with integrated submersible explosion-proof 3-phase motor. Approvals: EN 12050-2
The pump has an intermediate oil chamber pre-filled with non-toxic special oil.
The pump is fitted with a cable plug for easy dismantling. This plug is hermetically sealed with polyurethane to prevent water from penetrating through the cable into the motor.
A clamp between pump housing and motor ensures easy and safe dismantling and assembly. Inspection can be done in the field without any special tools.
The pump is fitted with a double shaft seal in the unique cartridge design. This makes it easy to replace the shaft seal very quickly in the field without any special tools. It also eliminates the risk of faulty installation.
The motor is insulation class F and has long-life, deep-groove, greased-for-life ball bearings.
The Grundfos EF AUTOADAPT pumps incorporate a controller, sensors and motor-protection. They only need to be connected to the mains supply. If several pumps are installed in the same tank, the control logic incorporated in the pump will ensure that the load is distributed evenly among the pumps over time.

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.
- 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.
category
- Submersible wastewater pumpsGrundfos submersible wastewater pumps are designed as sealed units combining a pump and integrated motor that can operate below the surface of wastewater. Submersible wastewater pumps are perfect in permanent installations for efficient removal of wastewater from a property whether from washing machines, sinks and showers or drainage from the garden.
