The main dock pumps (mostly 4-6 pumps, and possibly more) are arranged in the concave (U-shaped) cabin of the Floating Dock . E is a vertical and horizontal multistage pump with an annular casing or a spiral casing with a flow rate of 500-3500m3 / h.

The rotor can be pulled up. The pump shaft and the drive shaft that can be lifted up freely are installed in grease lubricated sliding bearings. Thrust bearings and driving shaft are arranged in a waterproof cabin a few meters above the pump.

The entire Floating Dock is divided into several closed compartments, some of which are called water compartments, which are used for irrigation and drainage. Ups and downs the dock. When sinking into the floating dock (filling water in the tank), the pump and its driving shaft are also located below the water. Each compartment has an inlet pipe, which is connected to the main water pump through a regulating valve.
The dock pump and driving shaft can be operated on the console, and the water level of each compartment and the inclination of the dock in the longitudinal and lateral directions can be controlled. In order to carry out regular maintenance on the floating dock and make the ship to be repaired into and out of the dock, the cabin can be pumped to different degrees according to the weight distribution. If the ship wants to repair the ship, it is called to enter the floating dock. Submerged in the floating dock water tank. Sink the floating dock until the water depth in the dock meets the draught requirements of the docking ship, draw the ship to be repaired into the dock, and then pump the water in the floating dock water tank. Contrary to dry dock. The lift fluctuation range of the dock pump is only a few meters.
