Ocmis VIR8A Hydraulic Drive Hard Hose Irrigator

Overview

The Ocmis VIR8A is a professional-grade hydraulic drive hard hose irrigator manufactured by Ocmis Irrigazione, Italy's leading irrigation equipment specialist. Engineered for large-scale agricultural operations, this machine combines exceptional stability with the capacity to handle large-diameter hoses up to 140 mm (5.51 in) and lengths extending to 730 m (2,395 ft). The robust 4-wheel chassis and comprehensive hydraulic control system deliver reliable performance across diverse terrain and demanding irrigation applications.

What distinguishes the VIR8A is its advanced 4-speed VR (Vario Rain) gearbox with synchronized speeds, representing the nerve centre of Ocmis's latest generation irrigator technology. This sophisticated system enables precise control over water application rates, delivering significant water savings whilst maintaining optimal irrigation uniformity. The integrated turbine with double built-in bypass ensures consistent operation with minimal pressure losses, whilst the hot galvanized chassis with epoxy resin coating and polyurethane paint finish provides exceptional durability in harsh agricultural environments. The machine accommodates both REFLEX and EXPLORER raingun options, offering versatility for varying field sizes and crop requirements.
