    What the HD 8/23 G Classic is built for

    Wherever there is no external power for demanding cleaning: construction sites, public parks and remote locations. The EU Stage V petrol engine and crankshaft pump deliver reliable performance day after day.

    Key features

    • 230 bar working pressure and 800 l/h flow.
    • Crankshaft pump with ceramic pistons. A crankshaft pump runs slower and cooler than an axial pump, so it lasts longer under daily use.
    • Tubular steel cage frame and puncture-proof wheels.
    • Thermo and safety valves plus a large water filter.
    • Compact and easy to transport by car.

    FAQs

    How many psi is the HD 8/23 G Classic?

    Its working pressure is 230 bar, which is about 3300 psi.

    What is a crankshaft pump and why does it matter?

    A crankshaft pump is a heavier-duty pump design that runs at lower speed, so it wears less and lasts longer under daily commercial use.

    Which HD Classic model suits my work?

    Talk to our team about the jobs you do and how often. As a guide: HD 9/25 G for the heaviest work, HD 8/23 G for daily contracting, HD 7/20 G for general property maintenance.
