Thorizontal centrifugal multistage pump can be utilised for a wide range of applications in the industrial and marine markets. This multistage pump is designed to pump low viscosity clean or slightly contaminated fluids without the presence of solid or fibrous particles. Common fluids pumped include fresh water, sea water and fuels (diesel, petrol and kerosene) and common applications include boiler feed, chemical, energy plants, mining, fire fighting, reverse osmosis, water treatment, pressurisation, dewatering, building systems, marine and cooling/heating conditioning (HVAC), petroleum, irrigation and water supply.

This multistage pump is capable of high pressures up to 55 bar and high flow rates of up to 1000m³/hr and is also very robust due to additional bearings being installed in the pump head, these remove strain away from the motor during operation.


The  horizontal multistage design has many benefits:

There are several options for flange configurations making it versatile when installing on sites with difficult pipework layouts.

It is standardised to BB4. Multiple closed impellers and diffusers are installed to allow it to achieve very high pressures.

This multistage pump has a maximum casing pressure of 63bar.

It is fitted with sacrificial wear rings which are replaced periodically, this means the casing and impellers are protected from premature wear.

If required,SANCHANG horizontal centrifugal multistage pump can be supplied with an external air powered or electric priming pump for applications where a suction lift is unavoidable.

Application

Multistage centrifugal pumps are used in various industrial applications due to their ability to transfer fluids at higher pressures. Here are some industries that use multistage centrifugal pumps:
Mining: In mining applications, multi-stage cemtrifugal pumps are used for dewatering operations, transporting slurries, and pumping water from mining pits.
 Fire fighting - Generates high-pressure water used in extinguishing fires.
 Boiler feedwater - To pump feedwater into a steam boiler.

 High-pressure cleaning - Generates a high-pressure stream of water to clean dirt and dust off objects like cars, windows, etc.

 Reverse Osmosis - Used for desalination.

 Irrigation - Multistage pumps are used to pump water via an irrigation system.

 Water circulation - Multistage pumps add pressure to the system, helping in the continuous circulation of water.
