Flow Q = 36 a 180 m3 / h head: h = 409 a 1056 m h = 270 1056 m (type ZDG pump)

Structure description:

This type of pump is single shell sectional multi-stage centrifugal pump, the suction and discharge nozzles vertical. Front, middle and later period of the poles connected into an organic whole, static combining surface depend mainly on metal surface is sealed between paragraphs, and is equipped with type O aprons as auxiliary seal.

Shaft seal: this type of pump shaft seal adopts the soft packing seal. A 80, DG85 DG45 a 80 type pump mechanical seal may be adopted. Packing gland, packing chamber with cooling water to cool. In the shaft seal is equipped with replaceable shaft sleeve to protect the pump shaft.

Bearing and balancing device: pump rotor by the pump shaft on both ends of the sliding bearing to support. This type of pump bearing with thin oil lubrication, and in circulating water cooling. The rotor axial thrust balance with balance disc. Between the balance chamber body and the front is equipped with return pipe. Rotation: driven by motor through flexible coupling. From the transmission direction, pump is clockwise.
