A concrete pump moves liquid concrete to different locations using a worm gear to push it through a piping system. There are three types of pumps: boom, line, and special purpose. Boom pumps are truck-mounted and used for large projects, while line pumps are portable and used for smaller projects. Special purpose pumps are used for specific applications such as repairing bridges or lifting concrete slabs.
A concrete pump is a mechanical device used to move quantities of liquid concrete to different locations. Most often, concrete pumps are referred to as “concrete pumps” because they actually pump concrete, which is made up of cement and other materials like water, sand, and gravel. There are three basic types of concrete pumps, the boom pump, the line pump and the special purpose pump; the pump used usually depends on the location of the job site and the amount of concrete needed. A concrete pump can usually be rented by the hour or day from specialist concrete companies.
How does it work?
Various types of concrete pumps are used for different types of applications, such as concrete can be poured, sprayed or injected, all of which require a different concrete pump. Regardless of the type, usually a concrete pump will use a worm gear to push concrete through a piping system to a specified location. The main difference between concrete pumps lies in how the pump is mounted and the type of pipeline through which the concrete travels from the pump.
Boom Pump
A boom pump is a truck-mounted concrete pump, also called a truck-mounted pump. Concrete boom truck cranes are used for large construction projects such as foundations, retaining walls, and high-rise structures. Their ability to move large volumes of concrete over long distances, vertically and horizontally, saves a lot of time and manpower. A crane-like robotic arm is remotely controlled to deliver concrete exactly where it’s needed.
Line pumps
Also known as a trailer or stationary pump, line pumps are usually mounted on trailers, making them portable. The concrete is delivered by trailer through rubber or steel hoses which are often manually connected to the pump. If the concrete is to be delivered to a remote location, additional pipes can usually be connected to extend the length of the pipe. These pumps are typically used for smaller projects, such as concrete slabs for single family homes, sidewalks, and some swimming pools, because they pump a smaller volume of concrete than boom pumps.
Pumps for special uses
Specialized concrete pumps are often used to force concrete through guns and nozzles when the location does not allow truck or trailer pumps. Products such as gunite and shotcrete are used to repair bridges and tunnels and are often applied with a special purpose pump. Pools can be built using cement products that can be sprayed through hoses with nozzles, and a process known as slabjacking, which is the process of lifting and repairing concrete slabs, also uses powerful special purpose pumps. Another circumstance that requires a special purpose pump is when pouring concrete in mines or tunnels; often, the pump is connected to a rail system that runs through the tunnel to deliver the concrete effectively.
