D Centrifugal Horizontal Hot Feed Water Boiler Pump Multistage Pump

Centrifugal Multi-stage Water Pump Product Overview

D, DG single suction multistage pumps are suitable to deliver the water or other liquids with similar physical.

D single suction multistage pumps are suitable to deliver the water or other liquids with similar physical and chemical properties as that of water, which temperature not exceed 80oC, are used for water supply duties in municipal engineering and factories as well as water drainage in mining.

DG pumps are suitable to deliver the water or other liquids with similar physical and chemical properties as that of water, which temperature not exceed 110oC, are used for handling feed water in small and medium power plant as well as chemical and other industries.

Type D/ MD/ DF/ DY multistage horizontal centrifugal pump consists of stator, rotator, bearing and shaft seal:

1) Stator: main parts is suction casing, stage casing, discharge casing and diffusor, they are screw up by poles to become a working house. The suction direction of D pump is horizontal, its discharge direction is upword; the discharge direction of MD/DF/DY pumps are upward, the suction direction is horizontal, they can be made upword according to user requirement.

2) Rotor: it is consist of shaft, impeller, balance disc, and shafe sleeve etc. Shaft supplied power to impeller. The axial force is balanced by disc. The shaft sleeve is mounted on shaft to protect shaft.

3) Shaft seal: it is usually adopted soft packing seal, consist of sealing house on suction casing, packing, blocking water ring, the seal house have some pressure water to cool. Lubricate and seal pump. Type D pump pressure water come from pump itself; type MD/DF/DY pump pressure water is come from pump itself or outer water, type MD/DF/DY pump usually adopt mechanical seal.

4) Drive: The pump is driver directly by motor through coupling.
