Keeping the 'Kaiserschleusse' Dry with PRORIL Dewatering Pumps

The submersible dewatering pumps from PRORILs' TANK series had found their way into the construction, mining, tunneling and quarrying sectors. A good example of their application is the use of two PRORIL TANK 6110 pumps during a construction project at the lock in Bremerhaven, Germany. The "Kaiserschleusse" was undergoing maintenance on the door system and our distributor had managed to supply two PRORIL TANK 6110 submersible pumps here.

20 Meter High Lock

First of all, a pumping system with a capacity of more than 1200 m3/h was used to create a watertight seal for the lock gates. The lock of over 20 meters high had to be emptied quickly.

Keeping the Lock Dry

In order to execute the work, the lock had to be kept dry. Four small submersible pumps were used to treat the leaking water. These included two PRORIL TANK 6110 dewatering pumps. The pumps ensured that the leakage water that seeped in was pumped away. In addition, a reserve pump was installed to pump back more than 500m3 of water per hour in case of emergency.
