Horizontal multistage centrifugal pumps are one of the most popular pump types in recent years. High lifting height, flexible flow range, high energy efficiency make these pumps an excellent choice for numerous applications. But are they the right choice for your needs? Sintech Pumps, the no.1 horizontal multistage centrifugal pumps suppliers in India walk you through the top benefits of these pumps, how they work, and more. Continue reading to know more about horizontal multistage centrifugal pumps and decide if it’s the right choice for you.

What are horizontal multistage centrifugal pumps?horizontal-multistage-centrifugal-pumps-1

Horizontal multistage centrifugal pumps are a type of centrifugal pumps that contain two or more impellers. Each stage in a multistage pump acts like a separate pump. They are primarily used in services requiring moderate to high TDH (Total Dynamic Head). All stages of a multistage are places within the same housing unit and installed on a single shaft. Up to eight stages can be placed on a single horizontal shaft. If you need more than that, you can use multiple shafts. Each stage reduces the head by the same amount. Sintech Pumps is the leading horizontal multistage centrifugal pumps suppliers in India for over three decades. Our series of multistage centrifugal pumps are built to world-class standards. The user-friendly design makes the pump suitable for both industrial and domestic applications.

What is the difference in working between Single Stage Centrifugal Pumps and Multistage Centrifugal Pumps?Single-Stage-Centrifugal-Pumps-and-Multistage-Centrifugal-Pumps

The more the number of stages a pump has, the higher the discharge pressure on the outlet. Multistage centrifugal pumps are designed to create higher pressure at each stage. However, the flow remains constant at all stages. Each stage in a centrifugal pump has a: Rotor Diffuser Directional return blades All these three components are housed within a single housing unit. The heat generated by a single-stage centrifugal pump depends on the circumferential speed and the type of impeller used. The biggest drawback of centrifugal pumps is that the rotational speed cannot be altered. As a result, this could become operationally inefficient in certain applications. However, if the number of stages can be increased, this operational inefficiency can be overcome. This is where multistage centrifugal pumps come into play. In a multistage pump, the transferred liquid flows through two or more impellers that are connected in a series. These pumps have several fluid chambers that are connected in series. The fluid enters the first chamber. At this stage, the fluid’s pressure is the same as the pressure on the suction line. Once the fluid leaves the first chamber, the pressure is further increased. This keeps on repeating until the fluid reaches the last chamber.

Advantages of Multistage Centrifugal PumpsMultistage-Centrifugal-Pumps-supplier

Here are the top advantages of using multistage centrifugal pumps when compared to single-stage centrifugal pumps: Multistage pumps are economical and can cover higher pressure ranges than a single stage pump. Another advantage is that it can help in increasing pressure at each stage. However, the one drawback of multistage centrifugal pumps is the increasing sensitivity to external vibrations. Multistage centrifugal are used in a variety of applications like boiler feed pumps, power station pumps, and other industries that require fluids at high pressures. Depending on the configuration and make, the rotors in these pumps can be mounted on a single shaft or different shafts. Multistage centrifugal pumps create higher pressure when compared with pumps with just one impeller. if high discharge pressures are required, then the rotors in the multistage pump are connected in series. On the other hand, if high capacity is needed, then the rotors are connected in parallel.

Multistage centrifugal pumps are divided into two major types: Vertical multistage pumps – these pumps have a vertically mounted shaft Horizontal multistage pumps – as the name implies, the shaft is horizontally mounted Let’s take a closer look at horizontal multistage centrifugal pumps. They have a modular interstage with segmented housing. The swivel assembly is fixed between the bearings, thereby making the entire assembly suited for high pressures. Horizontal multistage centrifugal pumps can handle higher flow rates when compared to vertical multistage centrifugal pumps. Horizontal multistage pumps are best used for: Boiler feeds Reverse osmosis applications Showers Pressure boosting High pressure cleaning Spraying Cogeneration Mine dewatering Snow making, etc. Multistage centrifugal pumps offer several benefits over regular single-stage centrifugal pumps. Energy savings, flexibility, ability to meet numerous flow/height requirements. Finding the right horizontal multistage centrifugal pump that best suits your application can be challenging.
