Description

A vertical multistage pump is a type of centrifugal pump that consists of multiple impeller stages stacked vertically along a common shaft. Each impeller stage consists of an impeller and a diffuser, and together they work to increase the pressure and flow of fluid as it passes through the pump.Here's a description of its key components and how it operates:
  1. Impeller: The impeller is a rotating component with vanes that impart kinetic energy to the fluid. In a vertical multistage pump, there are multiple impellers stacked on the same shaft. As fluid passes through each impeller stage, its velocity increases, which in turn increases the pressure.
  2. Diffuser: The diffuser is a stationary component that surrounds the impeller. It serves to convert the kinetic energy from the impeller into pressure energy by slowing down the fluid and redirecting its flow path. Each impeller stage is typically followed by a diffuser to maximize pressure buildup.
  3. Shaft: The shaft connects all the impeller stages together and transfers the rotational energy from the motor to the impellers. It must be designed to withstand the loads and stresses imposed by the rotating components.
  4. Motor: The pump is typically driven by an electric motor mounted above the pump assembly. The motor provides the rotational power needed to drive the impellers and generate the flow and pressure required.
  5. Casing: The casing encloses the impeller stages and provides structural support to the pump. It also contains the volute or diffuser passages that guide the fluid flow through the impellers.
Vertical multistage pumps are commonly used in applications where high pressure and flow rates are required, such as water supply systems, boiler feedwater, industrial processes, and irrigation systems. Their compact design and vertical orientation make them suitable for installations where space is limited. Additionally, they offer efficient operation and can handle a wide range of fluids, including clean water, liquids with low viscosity, and certain corrosive or abrasive fluids.
