Heavy-Metal-Free Synthetic Oil Provides Extreme Protection

Pyroshield Syn Hvy & XHvy Open Gear Lubricants are heavy-duty synthetic fluids designed to provide outstanding protection for high-load, heavy-shock applications, such as large shrouded open gears used in the mining, mineral processing and cement industries. Pyroshield Syn Open Gear Lubricants are non-asphaltic and environmentally friendly, containing no heavy metals. Each lubricant features a synergistic mix of Almasol®, LE's exclusive wear-reducing additive, and a unique combination of extreme pressure additives.

Proprietary Additive

N/A LE's proprietary additives are used exclusively in LE lubricants. Pyroshield Syn Hvy & XHvy Open Gear Lubricants contain Almasol.

Almasol® solid wear-reducing additive is able to withstand extremely heavy loads, chemical attack and temperatures up to 1,900ºF (1,038ºC). It is attracted to metal surfaces, forming a microscopic layer but not building on itself or affecting clearances. Almasol minimizes metal-to-metal contact and the resulting friction, heat and wear.

Pyroshield Solution

Wear / Downtime

N/A Some lubricants commonly used for open gear systems are identified only as "cushioning compounds," thus providing poor lubrication, which could result in excessive wear, frequent downtime for repairs, malfunctioning and high operating temperatures.

Pyroshield Solution
Pyroshield Open Gear Lubricants contain a synergistic mix of Almasol®, LE's exclusive wear-reducing additive, and a unique combination of extreme pressure additives. They exhibit exceptionally high film strength that helps them to withstand heavy loads and cushion shock loading in applications where commercial grade lubricants would fail. They also prevent the metal-to-metal contact that can lead to high operating temperatures and destructive wear.

Run-off / Housekeeping / Consumption / Cost

N/A Because many lubricants for open gear systems are not sufficiently tacky, they have to be applied in excessive amounts to provide a thick coating. It is not uncommon for the amount of lubricant applied to far exceed the amount recommended by the American Gear Manufacturers Association. In fact, some operators routinely use two to three times more than the recommended amount. Much of these lubricants will then run off, requiring extensive cleanup and waste disposal. Because of product run-off and the need for a thick layer, many traditional lubricants have to be purchased, used and disposed of in excessive amounts.

Pyroshield Solution
Pyroshield Syn Open Gear Lubricants are extremely tacky. LE's proprietary formulation allows the Pyroshield to cling tenaciously to metal surfaces, without build-up. The use of Pyroshield Syn Open Gear Lubricants has been shown to reduce lubricant consumption by up to 80 percent.

Build-Up / Damage

N/A Some traditional lubricants are tacky enough to adhere to the metal and not run off, but they cause another problem - they build up in the roots of the gear teeth, which can result in bearing stress and damage, as well as possible damage to foundations. In addition to possible damage, the removal of build-up can be messy and time-consuming.

Pyroshield Solution
Unlike these traditional lubricants that experience accumulation requiring periodic removal, LE's Pyroshield Syn Hvy and XHvy Open Gear Lubricants are fluid and will not accumulate. Cleanup is not required, and the use of Pyroshield Lubricants eliminates the possibility of expensive gear damage from unchecked accumulations.

Pyroshield Syn Open Gear Lubricants provide the same outstanding wear protection and reduced consumption provided by LE's Pyroshield 5182, 5180 and 5100 Open Gear Grease, but they have the added ability to flow freely in use. This eliminates the tendency to accumulate on shroud and pinion areas.
