Vertical turbine pumps are widely used in industries where water needs to be lifted from deep underground sources, wells, boreholes, or reservoirs. They offer high efficiency, reliability, and excellent performance in moving large volumes of water over long distances. Because of their vertical configuration, they are ideal for applications where space is limited and standard centrifugal pumps cannot be used.
This guide explains what a vertical turbine pump is, its types, components, working principle, and real-world applications, along with a diagram to help visualize key parts.
What Is a Vertical Turbine Pump?
A vertical turbine pump (sometimes called a deep well pum p or vertical centrifugal pump) is a multistage pump that is designed to pump water from deep underground sources. It consists of multiple impellers (bowls) arranged vertically, and each impeller increases the pressure as water flows upward through the column pipe.
Components of a Vertical Turbine Pump
A vertical turbine pump consists of several essential components that work together to deliver efficient pumping performance. Understanding these vertical pump parts is useful for selecting, operating, and maintaining the system.
1. Electric Motor
Mounted at the top of the pump, the motor provides the mechanical power required to rotate the shaft and impellers.
2. Drive Head
Supports the motor and allows the power to be transferred to the vertical shaft. It also houses the thrust bearing that handles axial loads.
3. Column Pipe
The long vertical pipe through which water travels upward from the bowl assembly to the discharge head.
4. Line Shaft
Connects the motor to the impeller shaft and transmits rotation energy.
5. Bowls / Impellers
Each impeller lifts the water and increases the pressure stage by stage. More impellers = higher head and pressure.
6. Suction Strainer
Prevents debris and solid particles from entering the pump and damaging internal parts.
7. Water Source / Intake
Where water enters the pump from a well, pit, river, or reservoir.
How Does a Vertical Turbine Pump Work?
The working principle of a vertical turbine pump is based on centrifugal force.
Working Process:
- Water enters through the suction strainer at the bottom.
- The rotating impellers accelerate the water, increasing pressure.
- Water rises through the column pipe and passes through multiple stages.
- It exits through the discharge head where it is directed into a pipeline.
This staged pressure increase makes vertical turbine pumps extremely efficient for deep well pumping.
Types of Vertical Turbine Pumps
Vertical turbine pumps can be categorized into the following main types:
1. Deep Well Vertical Turbine Pumps
Designed for wells and boreholes where the water level is very deep. Suitable for agriculture and municipal supply.
2. Short-Set Vertical Turbine Pumps
Used when the water level is closer to the surface, such as lakes, sumps, and open pits.
3. Can-Type Vertical Turbine Pumps
Installed inside a can or barrel and commonly used in industries with high pressure requirements, such as refineries and power plants.
