Dewatering in tunneling
Reliable drainage of tunnels
A tunnel construction is a complex worksite were many different variables need to be taken into consideration, flooding is one of them. Our drainage and sludge submersible dewatering pumps are lightweight, portable and start when you plug them in.
We provide a full range of reliable, trouble-free pumps for cost-effective tunneling. Our pumps cover the various pumping needs at a tunnel application.
Applications for dewatering in tunneling
- Tunnel shaft and shaft dewatering (1)
- TBM dewatering (2)
- Dig and blast dewatering (3)
- Cooling water circulation / General water supply / Fire water supply (4)
- Water cleaning and treatment (5)
- Sewage from sanitary facilities (6)
All pumps in the dewatering line can be called upon to do a good job. The drainage pumps are suitable for pumping water and dirty water mixed with light abrasives. When pumping water mixed with solids, the sludge pump is the better choice. Thanks to the low weight and slim design, the pumps are easy to move and with a pump range from 0.9 to 56 kW and a maximum head of 101 m our dewatering pumps are ready for any challenge.
Easy and safe to use, the trouble-free operation of our submersible dewatering pumps ensures more time in the water and less in the workshop. Our pumps’ high-efficiency motors and hydraulics minimize the total energy costs, while providing steady and reliable performance. The pumps come with features such as built-in compensation for incorrect phase order, motor protection and power check at start-up. The modular pump design makes it possible to use the same parts for different dewatering pumps. Less need for extra spare parts lowers your service costs.
The world’s smartest dewatering pumps for applications in mines, construction sites and tunnels are equipped with the innovative AquaTronic. AquaTronic ensures correct motor rotation, gives motor protection, allows the pump to start via a level sensor, and gives you all the pump performance information in your PC, plus much more.
Submersible drainage pumps J and XJ are excellent for pumping water and dirty water mixed with light abrasives. The pump design enables convenient transport, handling and installation. Pumps with built in AquaTronic unit will always have correct direction of impeller rotation, ensuring peak performance and reduced wear.
Submersible drainage center-line pumps JC and XJC are ideal for pumping water and dirty water mixed with light abrasives.
