MULTI STAGE PUMPS

Multi stage Pumps in dubai UAE

These pumps are known as multi-stage pumps that sink in the marine land dubai and Sharjah in the United Arab Emirates. Multistage pumps are pumps in which the fluid flows through several impellers that are installed in series.This type of pump is used in power plant applications.
A multi-stage pump operates by feeding one impeller to the next impeller and has the required number of impellers for the required pressure. The liquid enters the pump and then passes from left to right in sequence through a number of different impellers.

 

The relative simplicity of the design makes centrifugal pumps the most common and widely used type of pump on the market. Based on the number of impellers, centrifugal pumps can be classified into two categories: single-stage and multi-stage.

Single-stage pumps have a single impeller. Therefore, the discharge pressure is a function of the size of the impeller. Therefore, such pumps are a more suitable solution in higher flow and lower pressure installations.

Multistage pumps are able to provide flexible current and head amplitude and a relatively higher degree of energy efficiency, making them a great option for many applications.

 

What is a multi-stage pump?

A multi-stage pump is a pump in which fluid flows through two or more impellers installed in series. Hence, such a pump has several chambers or liquid phases that are connected in series. Each stage consists of an impeller, a combination of a diffuser, and returns guide vanes, all in one stage cover.

These impellers are installed in series and rotate on a single shaft driven by a power supply (usually a motor). The design of multi-stage pumps allows the fluid to pass through the chambers only linearly.

 

How do multi-stage pumps work?

After priming the pump, the fluid enters the pump inlet to the first chamber by pressing the suction line. The fluid then passes through different impellers in order from left to right (or vice versa, depending on the pump design). Finally, the liquid comes out with some high pressure. Each impeller enters the next impeller and the pressure increases at each stage.

The higher the number of stages or impellers of the pump, the higher the final discharge pressure. Although the fluid pressure increases with each step, the flow range always remains constant for a given RPM.

 

Types of multi-stage pumps

Multistage pumps are available in different types listed below, but the most common are vertical and horizontal pumps.

  • Horizontal multistage centrifugal pump (above ground)
  • Vertical multistage centrifugal pump (above ground)
  • Types of submersible pumps/tank
  • Lateral channel pump
  • Horizontal split case pump
  • Vertical turbine pump
  • Multi-stage sanitary pump

 

Advantages of using multi-stage pumps

  • Because multi-stage centrifugal pumps have multiple impellers, they can increase water pressure sequentially (ie from one stage to the next), so they offer higher pressures than single-impeller pumps of the same size.
  • The head is smaller at each stage, allowing relatively smaller impellers with tight tolerances, thus reducing leakage losses.
  • Multistage pumps also help reduce floor space. In addition, due to smaller impeller diameters and shorter distances, these pumps require less engine horsepower and therefore higher performance and efficiency.
  • For pumps with the same output pressure, increasing the number of stages reduces the noise level compared to single-stage pumps.

 

Disadvantages of multi-stage pumps

  • Compared to single-stage pumps, the design of multi-stage pumps is complex and consists of a large number of moving parts. As a result, maintenance of these pumps is relatively expensive and requires higher technical skills.
  • Also, harder tolerances do not allow any solids in the fluid flow, which is why multi-stage pumps are commonly used to transfer water or other low-viscosity fluids.
  • Due to the various steps in such pumps, the sensitivity of the pump rotor to external or natural vibrations increases.

 

Multi-stage pump applications

A multi-stage pump finds applications in a variety of industrial verticals that require fluid movement. For example, high-rise buildings need more pressure to deliver water to their upper tanks. Multistage pumps are widely used for such applications. They are also often used to increase the pressure of the water system or the continuous circulation of water in the system.

 

Other key applications include:

  • High-pressure cleaning
  • WATERING systems
  • Reverse Osmosis (RO)
  • Fuel delivery
  • Oil and gas production
  • Mine
  • Boiler pumps in power plants
  • Squeezing water to help put out the fire
  • Pressing water to create snow for use in sports and resorts
