SERMAC is an Italian manufacturer of truck-mounted concrete pumps.
A concrete pump piston (also known as a piston ram or piston cup) is a critical mechanical part used in concrete pump trucks and stationary trailers. It sits inside the machine’s delivery cylinders and provides the rhythmic pumping power required to push dense, heavy, and highly abrasive raw concrete through long pipelines.
