Eaton DYNAMAX™ EC850 500 Bar Spiral Hose. Raising the Bar on Ultra-High Pressure Spiral Hydraulic Hose. Eaton’s new DYNAMAX EC850 500 bar (7250 psi) hydraulic hose delivers dynamic performance for today’s more-demanding hydraulic systems.
Over the years, hydraulic system pressures have steadily increased. Higher pressures provide greater power! Eaton was one of the early innovators of hydraulic hose and Eaton’s corporate message is “Powering Business Worldwide” so it just makes sense that Eaton would develop this innovative and top-performing, new state-of-the-art, “high pressure” hydraulic hose incorporating the latest technologies in tube compounds, spiral wire reinforcement and abrasion resistant cover compounds. Hydraulic pump manufacturers around the world are developing pumps that operate up to 500 bar (7250 psi) pressure.
Development of the new DYNAMAX hose was done in conjunction with development of the latest high performance pump technologies now being offered in the marketplace. Eaton’s extreme test criteria closely simulate the rigorous and sometimes brutal performance and environmental requirements of real-life applications where these new systems are being used. To ensure long-lasting and effective hose performance, specific tests on EC850 were performed up to three million impulse cycles at working pressure, as compared to typical spiral hose specifications which require substantially fewer impulse cycles. Eaton’s EC850 hose and hose fitting combination yielded a cool down leakage of class 0 in accordance with SAE J1176.
