How A Concrete Pump Works And Its Types?

concrete pump

Nowadays, it’s common to find modern pumps equipped with the newest technology on working sites. And one of the most seen pumps is the concrete pump.

Whether it’s a residential project or any commercial project, the concrete pumping machine is approaching more and more contractors. This pump is an economical and efficient choice in a construction site.

Have you ever wondered what exactly a concrete pump is? Or how does this pump work? What are the different types of concreting pumping machines? We have answers to all your queries. Read the full article to know more!

Understand The Meaning Of Concrete Pump

It is a machine specially used to carry or convey the mixed cement from a batching plant or container to a job site. A pump helps to fill or cast cement at the exact location. The pump is a majorly needed tool for an extremely high-level construction project.

A concrete pump is one of the best ways to carry liquid material and common equipment over all the construction places. You will majorly find the pumping machine in high-rise or tall building construction areas.

A brief review of the pump history

As you know, for many decades, a concrete pumping machine has been an important part of any construction project. In 1957, Schwing GmbH invented the twin-cylinder hydraulic pump. Schwing GmbH is Friedrich W. Schwing’s company that first invented the concreting pump.

It worked by following:

  • One piston brings fluid into a cylinder with the help of a container or hopper. 
  • And the second one continuously pushes the concrete out in the pipes (which is released).
  • The pump also consists of a valve that finds which cylinder is available.
  • Furthermore, the valve discovers which cylinder can bring fluid and which one can discharge pipe wags every time pistons reach the ending.

Learn The Working Of Concrete Pump 

The concreting pump is the contractors’ first choice for seamless and stable working on a job site. So here we are mentioning the working of a concreting pup. Check out!

  • Firstly, if workers need cement, the mixing truck will do the same inside its rotating drum.
  • Later the truck pours its cement (in liquid form) into a hopper. It keeps beating the cement, which prevents it from getting hard.
  • Then the concreting pump makes the hopper empty for taking out the liquid concrete by a valve system. The pump sends cement or concrete to the place where it has to be cast by using auxiliary hoses at the same time.
  • The pump has a twin-cylinder hydraulic that consists of two-cylinder placed parallel.
  • Also, the cylinder consists of the drive pistons in it. It moves in a to-and-fro motion but oppositely.
  • If one cylinder moves back, then another will push forward. However, if one cylinder pushes forward, another one will go back.
  • The first chamber or cylinder placed first is a material cylinder that helps in hauling cement out from the hopper.
  • The second cylinder is also known as a discharge or releasing cylinder. It helps in pushing cement out from a pump in the places where it has to be placed.
  • On the other hand, it consists of two pistons in pairs. It works by pulling in and pushing out the liquid concrete volumes.
  • In the end, the two cylinders move to and fro because of the hydraulic continuous concrete flow. 

Types Of Concreting Pump

There are two types of concrete pumps. One is a concrete Line pump, and the second is a Boom concrete pump. 

A. Concrete Line Pump

The concrete line pumps are also termed conveying machines. It helps to fastly bring concrete into the job site by vertical and even horizontal pipelines. This p

ump uses a diesel engine as well as a motor engine.

Moreover, the line pump is capable of placing concrete fastly at hard-to-reach places. There are a few advantages of concrete line pumping, have a look.

  • Labor cost is lower than other pumps.
  • It is helpful to accomplish a construction task within less time.
  • With the help of this, concrete could be delivered in the hilly or hard-to-reach sites.
  • The site congestion decreases because using this pump needs fewer laborers.
  • Flexible pipelines that can be fixed anywhere.
  • Concrete strength improves thoroughly.
  • It’s effective and economical for various construction projects (commercial as well as residential).
  • For big-level construction, many pumps can be used.
  • Provides a stable working site and increases productivity.
  • A concrete line pump is best for making columns, slabs, dams, bridges, and foundations.

Now have a look at types of line concreting pumps. 

1. Truck Mixer Pump

It helps to mix all materials with the liquid concrete. Also, it has an attached pump that pumps directly by a mixer. It is effective in many applications.

2. Stationary Pump

Stationary pump is also called a trailer-mounted pump that consists of a pump mounted onto a little trailer. Furthermore, it doesn’t consist of a boom; that is why pump is essential to put separate pipelines and hoses for conveying the liquid concrete where it needs to be cast from a pump.

3. Static Truck Mounted Pump

It is placed on the truck beds, which helps the driver to put concrete directly on the job site. It doesn’t consist of setting booms.

B. Boom Concrete Pump 

It is a truck-mounted pump perfect for pouring large concrete from heights efficiently. The boom pump allows the user to pump a large amount of concrete in a short period. Furthermore, boom configurations are best for helping you maneuver in a busy job site and enable you to cast concrete in far-reaching places.

A boom pump comes in many folding configurations such as;

1. RZ

It is a multifold pump that has sections with a combo of Z and roll-and-fold sections.

2. Z and ZZ

You can fold the section of this pump into and fro. It is best fitted for restricted spaces as well as over a house.

3. Roll and fold

The roll and fold pump’s sections fold one under another in a curling motion. That is why it needs more space for unfolding.


Hopefully, you might get aware of the concreting pump’s working and its types. So, now you can choose the best concrete pump based on your need for a construction project. Both have their own advantages, whether a line pump or a boom pump.
