double stage pump

DS pump advantage 1.two stage pump 2.used for many field DS Two Stage Split Case Pump

1.Description

DS two stage split case pump, is a new generation of products combined the foreign technology and devoloped by our company after many years of research. It is the alternative to traditional section multistage pump. The fluid of DS pump is clean water, liquids containing a small amount of solid particles and corrosive liquid. It is mainly used for high-rise building water supply, industrial boilers, fire fighting, mine drainge, chemical, and avariety of industrial water systems.

2. The technology parameter of type DS pump: Pump outlet diameter Dn: 80--300mm Capacity Q: 100--1000m3/h Head H: 160--320m Temperature T: -20 degree celsius--150 degree celsius Solid parameter less than 80mg/L Working pressure less than 4Mpa 3. Description of pump type E. G 100DS-150x2A 100--refers to outlet diameter (mm) DS--refers to two stage split case pump 150--refers to head for one stage (m) 2--refers to the number of pump stage A--Changed outer diameter of impeller (the max diameter without mark)

4. Techenical advantages: 

1. with two-stage impellers back to back in form, the axial force is balanced automatically. Cancelled the necessary balance disc of the multistage pump, the reliability of pump is greatly increased and the trouble rate of the pump is reduced. It especially adapts to the application of the pump speed changes and the concentrated liquid's viscosity. 2. Being short bearing span, it increases the rigidity of th shaft. The pump runs smoothly and quietly. It specially adaptts to the quiet situations. 3. Excellent hydraulic model, pump efficiency is higher than the multi-stage pumps with the same parameter, more energy saving and better environmental protection. 4. with the structure of horizontal split case and suction inle t& outlet located in the lower part of the pump case, the pump is convennient to maintain, no need to remove the motor and pipe when maintenance. Therefore, it reduces the maintenace time and cost.
