A concrete pump is a tool mainly used for conveying freshly mixed concrete to the location on a construction site where it is needed to be placed. It works using a valve system and the basic fundamental of hydraulics.
Cost for ball-valve pumps is relatively low and there are few wear parts. Because of its simple design, the pump is easy to clean and maintain. The units are small and maneuverable, and the hoses easy to handle.
Pump manufacturers offer a variety of different line pumps to meet a wide variety of needs. Line pumps typically employ ball-valve-type pumps. While the smaller models are often called grout pumps, many can be used for structural concrete and shotcreting where low-volume output is suitable. They're also used for repairing underwater concrete, filling fabric forms, placing concrete in heavily reinforced sections, and building bond beams for masonry walls. Some hydraulically driven models have pumped structural concrete at outputs exceeding 150 cubic yards per hour.
