Geargard HVS  

Industrial Mobil, Canada

High Performance, Ultra-High Viscosity Open Gear Fluid

Product Description

GEARGARD HVS is an ultra-high viscosity lubricant, primarily intended for use in heavily loaded, low and medium speed open gears that may operate in boundary lubrication conditions. It is formulated with an ultra-high viscosity synthetic fluid and extreme pressure additives that provide outstanding performance under severe high and low temperature conditions. Geargard HVS is formulated to dispense very well in cold ambient temperatures as low as -10°C, while also providing excellent protection for gears operating in hot ambient conditions.

 

Features and Potential Benefits

GEARGARD HVS offers the following features and potential benefits when compared to conventional asphaltic diluent containing open gear lubricants.

  • Extended gear life provided by its ultra-high viscosity baseoil, excellent load carrying, antiwear, and adhesive properties.
  • Excellent pumpability at low and high ambient temperatures with conventional dispensing equipment.
  • Less frequent clean-up of the gear teeth and guard, helping to reduce the amount of maintenance and inspection work necessary on critical open gear systems. A clear product that enables visual inspection of the gears in operation.

 

Applications

GEARGARD HVS is designed to meet and exceed the requirements for the lubrication of heavily loaded grinding mills used in severe mining service.
