What Are the Different Types of Boiler Feed Pumps?

In the realm of industrial boilers, the role of a reliable and efficient boiler feed pump is critical for maintaining optimal performance and longevity. These pumps play a vital role in supplying the boiler with water, which assists in generating steam. There are various types of boiler feed pumps, and each is designed to meet specific requirements based on factors such as boiler size, pressure, and application.

Each comes with a wide range of benefits: for starters, boiler feed pumps prevent overheating (and subsequent damage) and extend the boiler’s life. They also decrease overall operation and maintenance cost while boosting efficiency and overall savings. Here are the key types of boiler feed pumps as well as their uses and advantages.

Centrifugal Boiler Feed Pumps

Centrifugal pumps are especially common types of boiler feed pumps, and for good reason. They operate on the principle of imparting kinetic energy to the boiler fluid through rotating an impeller. This kinetic energy converts to potential energy while fluid leaves the impeller and enters the volute casing.


Centrifugal boiler feed pumps are versatile and find applications in various industries, including power generation, manufacturing, and refineries.


  • Simple design and relatively easy maintenance
  • Suitable for a wide range of boiler sizes and applications
  • Relatively cost-effective compared to other types

Multistage Centrifugal Boiler Feed Pumps

Multistage centrifugal pumps consist of multiple impeller stages arranged in series. Each stage adds energy to the fluid, resulting in higher pressure. These pumps are well-suited for applications requiring higher pressure than what a single-stage pump can provide.


Power plants, large-scale industrial facilities, and applications with elevated pressure requirements benefit from multistage centrifugal boiler feed pumps.


  • Capable of handling higher pressure requirements
  • Efficient energy transfer due to staged impellers
  • Ideal for large industrial boilers

Positive Displacement Boiler Feed Pumps

Positive displacement pumps work by trapping a set amount of fluid and directing it into a discharge pipe. This type of pump includes reciprocating and rotary pumps. There are two types: reciprocating boiler feed pump and rotary boiler feed pump.

Reciprocating Boiler Feed Pumps

Reciprocating pumps move fluid using pistons or diaphragms. The back-and-forth motion creates a pulsating flow.


Reciprocating boiler feed pumps are used in power generation, petrochemical, and applications requiring precise flow control.


  • Suitable for high-pressure situations
  • Precise control over the flow rate

Rotary Boiler Feed Pumps

Rotary pumps, like screw pumps and gear pumps, operate by rotating elements to move the fluid. They offer a continuous, non-pulsating flow.


Rotary boiler feed pumps are used in food and beverage operations, chemical processing, and other processes in which a continuous flow is crucial.


  • Smooth and consistent flow
  • Suitable for applications with varying pressure requirements

Turbine Boiler Feed Pumps

Turbine pumps utilize the kinetic energy of a rotating impeller to move the fluid. These pumps are often integrated with steam turbines in power plants, taking advantage of excess steam energy.


Power plants, especially those using steam turbines, benefit from the integration of turbine boiler feed pumps.


  • Efficient use of excess steam energy
  • Well-suited for large-scale power generation applications

Choosing a Boiler Feed Pump

Boiler pumps are indispensable components of industrial boiler systems, as they ensure a reliable supply of water for the generation of steam. The choice of pump type depends on a wide range of factors, including boiler size, pressure requirements, and your specific project needs.

Each type of pump serves a unique purpose in the diverse landscape of boiler feed systems. Centrifugal pumps are simple, multistage centrifugal pumps have high-pressure capabilities, reciprocating pumps offer precision, rotary pumps provide smooth flow, and turbine pumps integrate with steam turbines.

Understanding the characteristics and advantages of each type allows industries to make informed decisions, ensuring the selection of a boiler feed pump that aligns with their specific needs. As technology advances and industry demands evolve, the role of boiler feed pumps continues to be pivotal in maintaining efficient and reliable boiler operations across various sectors.
