These are multi-viscosity oils with high SSI, shear-stable polymers that will stay in grade for thousands of hours under the most severe conditions in a variety of hydraulic system applications. They contain antiwear additives that protect pumps and motors at both high speeds and high pressures. The benefits of a multi-vis hydraulic fluid cannot be overstated. By using a year-round hydraulic fluid, seasonal changeover costs, including labor, downtime, the cost of flushing fluids and the disposal of the old oil, are eliminated. The shear-stable, high-viscosity-index formulation leads to cooler operating temperatures, resulting in longer equipment life. JAX multi-vis hydraulic fluids increase productivity by minimizing mechanical energy losses at start-up and making more hydraulic power available at operating temperatures to do the job in less time. Type Z and Hydra-Plate MV are ideally suited to machinery in severe cold weather or processing plants subject to wide swings in ambient temperature conditions.
