Ballast water is used for balancing purposes to stabilize ships. Once a ship has been relieved of its cargo, ballast water is pumped into respective tanks. When the ship is loaded up again, the water is pumped back to sea. This is performed by ballast pumps. Compared to centrifugal pumps, Börger Rotary Lobe Pumps have the advantage of being able to both fill and discharge tanks simply by reversing the direction of rotation. No extra control units are necessary. The rotary lobe pump is self-priming and dry-run capable. The pumps are frequency-regulated for more precise in balancing the ship. The pump installation is on deck as an ATEX standard.
