Building your own concrete pump could be a great solution if you’re starting a concrete project and need an efficient way to move concrete. When handling large amounts of concrete, a homemade concrete pump can be a more affordable option than purchasing or renting commercial equipment.
In order to build your own pump, you must first comprehend the fundamental ideas behind moving concrete and then modify those ideas to fit a do-it-yourself project. With a little creativity and some simple materials, you can create a pump that meets your unique requirements.
We’ll walk you through the steps of creating a homemade concrete pump in this guide. This homemade pump can help you complete your next project quickly and effectively, regardless of your level of experience doing projects yourself or if you’re just searching for a useful solution.
For modest building projects, a DIY concrete pump can be an affordable and useful alternative to expensive commercial equipment, enabling you to move concrete effectively. Making your own pump gives you complete control over the components and layout, allowing you to customize it to fit your needs and budget. This article will walk you through the process of building a straightforward but reliable concrete pump, providing advice on design, materials, and assembly to ensure dependable and seamless outcomes.

Classification of concrete pumps
Concrete pumps may be categorized differently. The kind of autonomy determines the first classification type. They are able to move around or remain still.
- stationary concrete pumps – the main advantages of this type of equipment are higher productivity, power, reliability and at the same time the equipment can operate under fairly high loads and in difficult conditions;
- mobile concrete pumps – preferable for those who do not want to buy equipment, but rent it. This type of pump is compact and easy to transport, can pump concrete mortar both vertically and horizontally.
Additionally, factors like size, engine performance, and power supply type may affect the classification. Concrete pumps fall into two categories: vacuum and piston types, depending on the kind of mortar supply they use.
- vacuum concrete pump – concrete is supplied by squeezing the solution out of the tray using a vacuum;
- piston concrete pump – the supply of concrete occurs using a working piston.
Piston
Piston A homemade concrete pump has a number of significant components, including a drive, cylinder, and piston. Each of these parts also comes with a specific amount of smaller spare parts. There are two check valves on the vessel known as the cylinder. Distilling the concrete solution from the receiver to the concrete water is their task. The coordinated operation of the piston and cylinder is what causes the process itself.
The piston starts operating first when the concrete pump is turned on. Due to the piston’s initial action, a discharge occurs inside the cylinder, encouraging the mixture to enter the next phase. After traveling to the end, the piston returns to its starting position. The concrete mixture is forced into the concrete water by pressure as a result of this operation.
Two pistons increase power and complicate technological processes in an industrial concrete pump. This is only advantageous, though, for substantial building projects, where the somewhat expensive cost of the device will soon be recouped. However, purchasing industrial-grade equipment for small-scale construction is excessively wasteful, especially considering how simple it is to construct a homemade pump with your own hands.
Materials and tools
In the event that you do choose to use a homemade concrete pump for your construction, you should prepare by gathering the required equipment, supplies, and most importantly, patience. You will require the following supplies and equipment to make a concrete pump by hand:
- a sheet of metal 5 millimeters thick;
- a metal pipe (preferably steel), for a cylinder;
- round metal sheets for making valves and a piston;
- a lathe to perform the necessary turning work;
- an engine (electric);
- a screwdriver;
- bolts and wrenches;
- steel or plastic pipes for concrete pipes;
- gearbox with a reduction gear;
- welded frame.
Cylinder and piston
The cylinder and piston are the primary components of this pump. Remember that the piston stroke should be 50 centimeters and the cylinder diameter should be 400 millimeters when producing these parts. If not, there will undoubtedly be more working cycles, which increases the risk of early wear on spare parts. You must ensure the highest level of precision in the piston and cylinder manufacture if you want to use your concrete pump for as long as possible and as effectively as possible.
Manufacturing process
To start, you will need drawing supplies like pencils, Whatman paper, compasses, and a ruler in order to create a drawing of the final product. You can locate ready-made drawings if you lack the necessary skills to design your own. However, you should use caution as ready-made drawings for your concrete pump might have mistakes in them. If you have both working hands and an engineering degree, this is a great choice.
Automatic drive
If you choose to build a concrete pump by hand, keep in mind that the apparatus will require a drive. An electromechanical option would be the most optimal. Its low cost and simpler manufacturing process set it apart from a hydraulic drive. A three-phase asynchronous motor, a reduction gear, and a transmission mechanism (which converts rotary motion into reciprocating motion) are required to make it.
A kingpin must be attached for the reciprocating motion to be transferred to the device’s piston. Because it doubles as a bed, this is the precise spot where a welded frame will be required. All that matters is that the corners are made of premium metal.
Check valves require special consideration when building a cylinder. They only use alloyed steel that is incredibly strong because no other kind of metal can survive repeated distillation processes of concrete mixture.
| Aspect | Description |
| Purpose | A homemade concrete pump helps in transferring concrete from a mixer to the construction site more efficiently. |
| Materials | Commonly used materials include PVC pipes, a motor, hoses, and a few metal parts for reinforcement. |
| Components | Main components are the pump body, suction pipe, discharge pipe, and motor. Some designs also include a hopper for holding concrete. |
| Assembly | Assembly involves connecting pipes and hoses, securing the motor, and ensuring all joints are sealed properly to prevent leaks. |
| Testing | Before use, test the pump with water to check for leaks and ensure that it can handle the flow rate required for concrete. |
| Maintenance | Regularly check for wear and tear, clean the pump after each use, and replace any damaged parts promptly to ensure longevity. |
It can be a satisfying project that saves you money and gives you a sense of accomplishment to build your own concrete pump. If you have the necessary supplies and do-it-yourself abilities, you can make a working pump that suits your needs for small to medium-sized concrete projects.
Your DIY concrete pump will work efficiently and safely if you closely follow the instructions and take safety measures. Its lifespan can be increased and its functionality maintained for upcoming projects with appropriate maintenance and use.
Building a concrete pump on your own is a great way to expand your construction toolkit, regardless of experience level. It’s a useful solution that can make your concrete tasks easier and increase your productivity on the job site as a whole.
