Deep lift System for KSB Submersible Motor Pumps KRT. The Deep lift station from KSB is a simple and effective solution which allows lifting and lowering of the KRT Submersible Pumps without the need for additional chain. No matter the distance, it can lift and lower the pump on a crane in one single operation. With Cable clamps at the top of the sump, it makes it easy to maneuver. The Deep Lift System is then guided by the rails and will connect to the pump lifting bail automatically even if the top of the pump cannot be seen due to the water level.
