Keeping the 'Kaiserschleusse' dry with PRORIL submersible dewatering pumps

The submersible dewatering pumps from the PRORIL Tank series find their way well into the construction, mining, tunnelling 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. Our distributor Rental Pumps supplied two PRORIL Tank 6110 submersible pumps here.

20-Meter High Lock
Initially, a pumping system with a capacity exceeding 1200 m³/h was deployed to establish a watertight seal for the lock gates. Given that the lock stands over 20 meters high, it was crucial to empty it quickly.

Maintaining a Dry Lock
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.
