HydraSafe HiVi™ is a high viscosity index, high performance anti-wear hydraulic fluid specially designed to meet the needs of industrial and modern high-pressure hydraulic systems. HydraSafe HiVi™ is environmentally sensitive due to its zinc free anti-wear additives that provide a well-balanced performance in a wide range of applications. The product line is constructed from high quality thermally stable base stocks to deliver extended drain intervals. The shear stable high viscosity index offers a wide operating temperature range while maintaining superior film strength to protect internal componentry. The Zinc free anti-wear system provides excellent protection of yellow metal often found in gear, vane, and piston pumps. HydraSafe HiVi™ has been rigorously tested for its durability while simultaneously passing environmental tests to deliver a low toxicity, environmentally sensitive hydraulic fluid.
