Submersible Pump GRUNDFOS EF30 pump have a single-vane, semi-open impeller for 30 mm free passage, designed for pumping effluent and other liquids such as drainage and surface water with fibres and small impurities.
PRODUCT DESCRIPTION :
- The compact design makes the pump suitable for both temporary and permanent installation.
- Has an intermediate oil chamber pre-filled with non-toxic special oil.
- 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.
APPLICATION :
