A line pump is a type of concrete pump used to transport liquid concrete from a mixer to a construction site. It consists of a pump unit connected to a series of pipes, allowing for precise placement of concrete in hard-to-reach areas. Line pumps are often used for smaller projects, such as residential foundations and slabs. These pumps are typically powered by a diesel or electric engine and can handle various types of concrete mixtures. They are favored for their versatility and efficiency, making them ideal for projects that require accurate and controlled concrete delivery, such as foundations and slabs.
