              Energy recovery turbine
              Performance:
              Flow rate (Q): 160 ~ 515 m3 / h
              Head (H): 1490 ~ 2680 m
              Design features:
              DG is a high pressure boiler feed pump inlet and outlet for the upright single-hull section multistage centrifugal pump, tighten the bolts with the water, middle, and water connection into one paragraph. Pump the water segment, the middle section of the static sealing surface water by the metal surface seal.
              Bearing and balancing devices: support for the pump rotor bearing. Forced lubrication bearings, lubricating oil from the auxiliary pump, pump head and pump supplies. The rotor axial thrust to balance with the balance disc.DG400-180 type and DG520-230 pump also comes with thrust bearings.
              Seal: DG520-230-type pump seal is floating ring seal; DG400-180 type mechanical seal pump shaft; other soft packing seal the pump with water cooling.
              Department with the seal to protect the replaceable shaft sleeve.
              Transmission: The gear-type pump driven by a prime mover coupling. DG520-230 pump also has growth box.From the transmission direction, the pump is clockwise rotation.
