The SERMAC 4Z27 concrete pump is designed with a versatile 4 section, “Z” fold boom. Thanks to a minimum boom opening height of just 6,75 m and pipeline of Ø 125 mm it provides the ideal solution for placing concrete in city centres or areas with restricted space, where large size concrete pumps could have difficulties in access and setting up. The 4Z27 is suited to small jobsites, indoor and outdoor work on commercial and residential projects or any job that requires a limited set-up space. The pump can be easily maneuvered thanks to its assembly on a 2 axle truck with a wheelbase of 4,400  4,800 mm. The 4Z27 combining boom agility with minimal setup space for the outriggers that other machines cannot reach. The pumping group G9 at open circuit hydraulic system model AG9M10-150-80 offers reliability and high performance theoretical concrete output up to 150 m³/h and pressure up to 80 bar.
