Boom Pumps BMS 22 Meter Boom New to the fleet in 2023, the 22 Meter Boom is a great addition to the smaller mobile boom pumps here at Ramcrete. The Free Flow Hydraulic system used in the BMS 22 meter boom means there is less noise and a decrease in the bouncing of the boom, which has made this compact concrete pump a popular choice to date. With a similar output and set up space as the 20 meter boom, this is a more powerful mobile machine. 22m 19m 85m³/hr
