THE MUST-HAVE HANDBOOK FOR CENTRIFUGAL PUMPS Page 14 Vertical Multi-Stage Pumps A vertical multi-stage pump has multiple liquid chambers (stages) that are connected in series. Fluid enters the first chamber at suction line pressure and leaves at some elevated pressure. Upon leaving the first stage, the fluid enters the second stage

Multistage centrifugal pumps are a type of centrifugal pump that consists of multiple impellers arranged in series within the same pump casing. These pumps are widely used in various industrial applications due to their ability to generate high pressures and handle high flow rates efficiently. In this article, we will explore the different types, uses, benefits, and drawbacks of multistage centrifugal pumps.

Multi-Stage Centrifugal Pump Function

The primary function of a multistage centrifugal pump is to increase the pressure of the fluid being pumped. Each impeller in the pump adds energy to the fluid, resulting in a cumulative pressure boost as the fluid passes through each stage. This allows multistage centrifugal pumps to achieve higher discharge pressures than single-stage pumps, making them ideal for applications that require high pressures.

Single Stage vs. Multistage Pump

Single-stage centrifugal pumps have only one impeller and are suitable for applications where moderate pressure increases are required. In contrast, multistage centrifugal pumps have multiple impellers and are designed to handle high-pressure applications. The main advantage of multistage pumps over single-stage pumps is their ability to generate higher pressures efficiently.

Multi-Stage Pump Explained

In a multistage centrifugal pump, each impeller is connected in series within the pump casing. The fluid enters the pump through the suction inlet and passes through each impeller, where it gains kinetic energy. The kinetic energy is then converted into pressure energy as the fluid passes through the diffuser vanes before entering the next impeller stage. This process is repeated for each impeller stage, resulting in a significant increase in pressure.

Multi-Stage Centrifugal Pumps Diagram


The diagram above illustrates the basic configuration of a multistage centrifugal pump. As the fluid passes through each impeller stage, its pressure increases, allowing the pump to deliver high-pressure output.

Multi-Stage vs. Single Pumps

When comparing multistage centrifugal pumps to single-stage pumps, the key difference lies in their pressure capabilities. Single-stage pumps are limited in the pressure they can generate, while multistage pumps can achieve much higher pressures due to the multiple impeller stages. This makes multistage pumps more suitable for high-pressure applications.

Multi-Stage Centrifugal Pumps

Multistage centrifugal pumps are commonly used in industries such as oil and gas, chemical processing, power generation, water treatment, and more. These pumps are ideal for applications that require high-pressure delivery of liquids, such as boiler feedwater, reverse osmosis, pressure boosting, and high-pressure cleaning systems.

Multi-Stage Vertical Centrifugal Pumps

Multistage vertical centrifugal pumps are a specific type of multistage pump that is designed for vertical installation. These pumps are commonly used in applications where space is limited, and vertical pumping is preferred. The vertical configuration of these pumps allows for efficient use of space and easy installation in tight locations.

High Pressure Multistage Centrifugal Pumps

Multistage centrifugal pumps are used in a wide variety of industrial applications. Learn the different types, uses, benefits and drawbacks of multistage centrifugal pumps.

On a boat having an inboard motor that turns a shaft attached to an external propeller, the shaft passes through a stuffing box, also called a "packing box" or "stern gland" in this application. The stuffing box prevents water from entering the boat's hull. In many small fiberglass boats, for example, the stuffing box is mounted inboard near the point the shaft exits the hull. The "box" is a cylindric.
