4ZR20

Overview

The SERMAC 4ZR20 City-Pump is fitted with a “ZR” folding boom for ultimate versatility. With a minimum opening height of only 4,2 m and pipeline of Ø 125 mm, this pump provides the ideal solution for placing concrete in city centres or confined spaces where medium size concrete pumps would have difficulties in accessing and setting up. The 4ZR20 City-Pump is perfect for medium-small jobsites, working inside or any concrete pumping that requires a limited ground space to set-up. The 4ZR20 can easily operate in urban areas thanks to the assembly of the truck on a 2 axle wheelbase of 3,690 – 3,900 mm. The pumping group G9 at open circuit hydraulic system model AG9M10-100-80 offers reliability and high performance theoretical concrete output up to 100 m³/h and pressure up to 80 bar.
