These are multi-viscosity oils with a shear-stable polymer 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. 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. JAX Hydra-Plate MV contains a non-zinc antiwear package.
