Purpose and principle of operation of equipment
It’s important to carefully follow production technology when building concrete structures. In many respects, a structure’s ability to withstand the test of time is dictated by the materials’ ability to meet prescribed standards. The process of feeding the solution to the concreting point is the biggest issue facing builders, along with preserving the quality of the concrete mixture.
With specialized equipment, a continuous supply of the mixture to the site can be guaranteed. Concrete pumps that are stationary are made to address this issue.
- This type of concrete pump is called stationary because, although the unit is installed on a chassis, it cannot move independently.
- The concrete pump is a trailer device that can be moved around the construction site. Freight platforms are used for transportation over long distances.
- The concrete pump can work with concrete of different grades, supply it horizontally or vertically. The latter circumstance is very important when constructing high-rise buildings.
This is fascinating! A record was set in 2008. A stationary Putzmeister installation in the United Arab Emirates poured concrete mortar to a record 606 meters during the construction of the Burj Khalifa tower.
- The mixture is fed into the concrete pump from the mixer. For this purpose, the unit is equipped with a receiving hopper equipped with a vibrating grid to protect against penetration of concrete mix filler fractions, the size of which exceeds the parameters specified for a specific model of equipment.
- In the hopper, concrete accumulates for feeding to the concrete pump and subsequent transportation through the concrete pipeline.
- The concrete pipeline is a system of pipes through which the solution is delivered to the place of laying.
Crucial! Large aggregate sizes in concrete shouldn’t be greater than one-third the diameter of the concrete pipeline (this information must be included in the unit’s operating instructions).
- Proper laying of the concrete pipeline is one of the most important components of normal operation of the equipment.
- When installing pipes, the bending angle must not be allowed to exceed the maximum permissible value (90 degrees).
- Pipes are not simply connected, they should be fixed to supports.
- Horizontal sections of concrete pipelines are placed on pads, vertically installed pipes or those mounted at an angle must be fixed to masts or scaffolding.
- In addition to pipes, the concrete pipeline can be equipped with gutters or large-diameter flexible hoses.
One of the key components of the concrete mortar transportation system is a water pump. The concrete pipelines are continuously flushed with its help. A hatch system is incorporated into concrete pipelines to eliminate surplus liquid.
Note: With the solution, the concrete pump shouldn’t be left running for longer than 20 minutes. If not, the concrete can stop the pump from hardening. Furthermore, it is a difficult task to remove the hardened material from the unit and the concrete pipeline.
Every ten minutes, the concrete pump should be started at low power if a lengthy break is needed during construction. Blockages in concrete pipelines are the most frequent issue that occurs when concrete pumps are in use, and they can cause work to stop.
Congestion can occur because of:
- errors during installation of concrete pipeline;
- installation downtime for a long period of time without idle pumping;
- poor water pump performance;
- lack of lubricant on the walls of the concrete pipeline;
- poor cleaning of equipment after the previous start-up.
At the end of the route, a transportable distribution boom can be placed (pictured).

The construction industry, which is governed by GOST ISO 21573-1-2013, uses a variety of concrete pumps. The following traits could set them apart:
Engine type
Electric or diesel engines can be used to power stationary units. On closed construction sites, equipment with electric motors is typically utilized.
Unfortunately, because it is common for many construction sites to lack access to electricity, it is not very popular in our country. As a result, diesel-powered models are more widely available.
Drive type
Concrete pumps can be driven by hydraulic or mechanical means. The majority of models nowadays come with a hydraulic system. It can produce higher pressure, which raises the pump’s power and increases the amount of distance the mixture can be moved.
The working piston’s longer and smoother stroke, which guarantees the mixture moves uniformly along the concrete pipeline, is another benefit of hydraulics.
Pump design
Concrete mortar is supplied by rotary and piston concrete pumps. The type of equipment selected is determined by the task at hand.
Piston concrete pumps
The way the system works is that the solution is drawn in, and then the piston’s return movement forces the concrete into the concrete pipeline. The productivity of piston units is higher than that of rotary ones.
However, they are prone to quick wear because small filler particles and concrete milk get inside the mechanism. The uneven distribution of the solution supply is another drawback of this kind of system, which is frequently intolerable.
Rotary concrete pumps
Rubber-coated rollers mounted on the rotor transfer the concrete mixture from these units to the concrete pipeline. Mixtures with large-fraction filler can be used with such a system.
This type of concrete pump is characterized by its low noise level. Reverse (movement of the solution in the opposite direction) can begin inside the concrete pipeline if blockages are formed from the concrete mixture.
Typically, rotary equipment is designed to handle modest amounts of work. These units are more practical to use at locations where concrete reinforcement is done frequently. Increased hose wear in rotary systems is a serious issue since filler, particularly crushed stone, damages the hoses.
The gate valve is integral to the pumping system. It either opens the mixture’s path to the concrete pipeline or, on the other hand, closes it off.
These valves come in three varieties:
While cast iron is the only material used in the final type of valve, steel and cast iron are used in the first two.
