Submersible Pump GRUNDFOS DP (Drainage Pumps) cover a motor range of 0.9-2.6 kW. The pumps are fitted with a semi-open multi-vane impeller capable of handling solids up to 10 mm in size. The pump has a multi-vane, semi-open impeller for 10 mm free passage and is suitable for pumping drainage and surface water, groundwater, industrial process water without solids and fibres.
PRODUCT DESCRIPTION :
- The compact design makes the pump suitable for both temporary and permanent installation.
- GRUNDFOS DP Series 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.
- Submersible Pump GRUNDFOS DP 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 pump has DN 65 discharge port and is ready for installation either free-standing or on an auto-coupling system
