Concrete Pumps- Types and Advantages in Construction

Concrete pumps play a crucial role in the construction industry, enabling efficient and precise placement of concrete in various construction projects. In this article, we will discuss the different types of concrete pumps and their advantages in construction.

Pumping concrete is the process of transferring freshly mixed concrete from a central mixer or truck-mounted mixer to its final placement location using a concrete pump. This method is commonly employed in construction projects to efficiently and precisely place concrete in various positions, including high-rise buildings, foundations, slabs, and hard-to-reach areas.

What is Concrete Pump?

A concrete pump is a specialized machine used in construction to transfer freshly mixed concrete (typically a mixture of cement, aggregates, water, and sometimes additives) from a central mixing point, such as a concrete mixer truck or batching plant, to the desired location where it’s needed for construction purposes. Concrete pumps are designed to efficiently and precisely transport and place concrete in various locations, including hard-to-reach or elevated areas. They are a fundamental tool in the construction industry, particularly for large and complex projects.

Types of Concrete Pump

Concrete pumps are versatile equipment used to transfer liquid concrete from a concrete mixer or batch plant to the construction site. They provide a reliable and efficient method for placing concrete in various locations, ensuring precision and speed. There are several types of concrete pumps, each designed for specific construction applications and requirements. The two primary categories of concrete pumps are boom pumps and line pumps. Within these categories, there are various subtypes and specialized pumps. Here are the main types of concrete pumps:

1. Boom Pump (Truck-Mounted Concrete Pump)

A boom pump is mounted on a truck chassis and has a long, articulating arm known as a boom. The boom can be extended and maneuvered in different directions, allowing the pump to reach high or distant locations. Boom pumps are commonly used for high-rise buildings, bridges, and other tall structures where precise concrete placement at significant heights is required.

Truck-Mounted Boom Pumps

These are the most common and versatile concrete pumps. They are mounted on trucks and have a long, articulating boom that can extend and maneuver to reach elevated or distant locations. Truck-mounted boom pumps are ideal for high-rise buildings and large construction projects.

Self-Climbing Placing Booms

These are tower placing booms that can climb the structure as it rises. They are commonly used in the construction of tall buildings and provide continuous concrete placement at various heights.

Advantages of Boom Pump

  • Reach: Boom pumps have an articulated arm (boom) that can extend and reach significant heights and distances. This makes them ideal for tall buildings, bridges, and other structures where concrete needs to be placed at elevated or remote locations.
  • Accuracy: Boom pumps provide precise control over the placement of concrete. The operator can maneuver the boom to direct the concrete exactly where it’s needed, reducing the risk of errors.
  • Efficiency: Boom pumps can place large volumes of concrete quickly, which helps speed up construction projects. This efficiency can lead to cost savings by reducing labor and construction time.
  • Versatility: Boom pumps are versatile and can be used in a variety of construction scenarios, including both residential and commercial projects.
  • Safety: They allow operators to work from a safe distance, reducing the risk of accidents or injuries associated with manual concrete placement.


  • Boom pumps are typically larger and heavier than line pumps, which can make them less suitable for tight or confined job sites.
  • They may require a larger crew for operation and setup.

2. Line Pump (Trailer-Mounted Concrete Pump)

A line pump is typically mounted on a trailer and is more compact and portable than a boom pump. It uses a system of hoses to transfer concrete from the pump to the desired location. Line pumps are suitable for smaller construction projects, residential work, and situations where flexibility and precise placement are essential.

Trailer-Mounted Line Pumps

These are portable pumps mounted on trailers, making them suitable for smaller construction projects and residential applications. They use a system of hoses to move concrete from the pump to the placement location.

Skid-Mounted Line Pumps

These are similar to trailer-mounted line pumps but are mounted on a skid rather than a trailer. They are compact and can be easily transported and set up on the job site.

Truck-Mounted Line Pumps

These are line pumps mounted on trucks, providing mobility and versatility. They are often used in mid-sized construction projects and are a cost-effective option for precise concrete placement.

Advantages of Line Pump

  • Flexibility: Line pumps are more compact and portable, making them suitable for smaller construction sites or locations with limited access. They can navigate through tight spaces and around obstacles.
  • Cost-Effective: Line pumps are often more cost-effective for lower-volume concrete placements, such as residential foundations, swimming pools, and sidewalks.
  • Versatility: They can handle various types of concrete mixes, including those with additives or admixtures.
  • Ease of Setup: Line pumps are quicker and easier to set up than boom pumps, making them a good choice for smaller, and shorter-duration projects.
  • Safety: Operators can work from a safe distance, reducing the risk of accidents or injuries associated with manual concrete placement.


  • Line pumps have limited reach compared to boom pumps. They may not be suitable for very tall structures or projects that require concrete placement at significant heights.
  • They typically have a lower output capacity than boom pumps, so they are better suited for smaller-scale jobs.
  • Line pumps may require additional labor for the setup of hoses and pipes.

3. Specialized Pumps

Shotcrete Pumps

These pumps are designed specifically for the application of shotcrete (sprayed concrete) and are commonly used in tunneling, slope stabilization, and swimming pool construction.

Grout Pumps

Grout pumps are used for precise placement of grout, a mixture of cement, sand, and water. They are used in applications such as foundation repair, soil stabilization, and sealing cracks.

High-Pressure Pumps

These pumps are capable of pumping concrete at higher pressures, making them suitable for applications where increased pressure is required, such as high-strength concrete mixes or long-distance pumping.

Squeeze Pumps

Squeeze pumps operate by squeezing a rubber hose to move the concrete. They are often used for pumping highly viscous or abrasive materials and in applications like underground mining.
