Reliable operation

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.
