Product Description

Anti-Corrosive Stainless Steel Pumps Multistage Centrifugal Salt Brine Pump

The multistage centrifugal pump consists of several stages with a centrifugal impeller and diffuser. The number of stages and motor speed determine the duty point of this type of pump used in high pressure applications.

The stages are interconnected with the first stage feeding the next and so on, increasing the pressure with each stage. The most commonly used version is the version in which the pump shaft is mounted using ball bearings in a bearing bracket outside the liquid section of the pump. Between the impeller and the bearing, the shaft seal ensures a liquid and airtight passage of the shaft into the pump housing.

The pump can be installed horizontally or vertically. In addition, various material options are available for both the impeller package and the seals. As with any pump, the system parameters determine which pump is best used in your system: flow rate and composition of the medium are some of the requirements for making a good selection and we can assist you with advice and action.
 

Versions of vertical multistage pumps

• Low NPSH multistage pumps
• Immersion multistage pump for coolant or cutting oil
• Standard vertical and horizontal multistage pumps
• Multistage pumps and booster pumps for high temperature
• Condensate pumps, deep well pumps and boiler feed pumps

Horizontal and vertical booster pumps

All pumps are available in horizontal and vertical multistage pumps. Depending on the desired construction, we adapt the entire pump. We can place the standard pump vertically by supplying special pump supports.

Low NPSH or high temperature

The pumps we supply can be specially adapted to higher temperatures. We can also have the pumps designed for very low NPSHa values. We achieve this by using special circulation covers and impellers or by placing a special inducer in the suction of the pump. We can therefore guarantee a cavitation-free booster pump or multi-stage pump for, for example, condensate systems, boiler coding systems and deep well systems.


Advantages of a multistage pump

• Creates high pressure, which makes it suitable for heavy applications
• Suitable for various drives
• Available in various materials and with different seals, for every application
• Low maintenance
