Equipower™ Ultra HVI Hydraulic Oil (6522)

Product Description

Extended-Life Oil Provides Smooth Hydraulic Power

A long-lasting, non-foaming oil designed to extend the life of hydraulic systems, Equipower™ Ultra HVI Hydraulic Oil (6522, 6532, 6546) offers superior protection against water contamination, rust, corrosion and oxidation. This high viscosity index formulation contains Monolec®, LE’s exclusive wear-reducing additive, and outperforms other commercial hydraulic oils in thermal, oxidative and hydrolytic stability. It is recommended for hydraulic applications with operating temperatures that fluctuate widely on a daily basis.

Beneficial Qualities

Long-Lasting, Cost-Saving Service

  • Provides longer service life than other commercial hydraulic oils
  • Extends drain intervals when properly maintained
  • Reduces oil consumption, including need for make-up oil
  • Minimizes labor and downtime required for oil changes
  • Eliminates fade and chatter by breaking up foam

High Viscosity Index Formula

  • Ensures smooth, uninterrupted power flow over wide temperature range
  • Increases energy efficiency, which also reduces greenhouse gas emissions

Wear Protection

  • Protects metal components from scuffing, galling and other wear
  • Minimizes equipment downtime and failure
  • Is compatible with most seals and hoses
  • Reduces need for replacement parts and labor

Water, Rust, Corrosion & Oxidation Resistance

  • Separates rapidly from water, allowing for easy water drain-off
  • Prevents rust and corrosion with R & O inhibitors
  • Provides superior oxidation resistance
    • Reduces sludge and varnish formation
    • Prevents plugged orifices and sticky valveso Maintains system cleanliness

Relationship of Viscosity to Pump Efficiency

Hydraulic pumps convert mechanical energy from electric motors or internal combustion engines into fluid flow; however, some energy is always lost during this process. Mechanical losses occur due to fluid friction at higher viscosities, while volumetric losses due to internal fluid leakage occur at lower viscosities. Each hydraulic pump has an optimum operating viscosity range that will provide maximum pump efficiency by keeping mechanical and volumetric losses to a minimum.

Relationship of Viscosity to Pump Efficiency

A hydraulic pump manufacturer states that an operating fluid viscosity of 20-40 cSt provides optimal energy efficiency in a piston pump. They also state that the fluid viscosity at cold startup should not exceed 1,000 cSt, or fall below 14 cSt at any time during operation. The high viscosity index of LE’s Equipower Ultra HVI Hydraulic Oil enables the f luid to remain within the optimal operating viscosity range throughout a wider operating temperature range than non-HVI fluids. Ultimately, this helps increase the bottom line by increasing pump efficiency in the form of reduced mechanical and volumetric losses. Less energy consumption also yields a smaller carbon footprint by reducing greenhouse gas emissions.

Proprietary Additives

LE’s proprietary additives are used exclusively in LE lubricants. Equipower™ Ultra HVI Hydraulic Oil contains Monolec.

Monolec® wear-reducing additive creates a single molecular lubricating film on metal surfaces, vastly increasing oil film strength without affecting clearances. An invaluable component in LE’s engine oils, industrial oils and many of its other lubricants, Monolec allows opposing surfaces to slide by one another, greatly reducing friction, heat and wear.
