Pyroshield - Open Gear Lubricants

Open Gear Lubricants

Grinding, pulverizing, breaking - open gears can take a beating

Large open gears take a severe beating on a daily basis. Challenging conditions include outdoor environment, extended service operation, dust, silica, water, extreme heat and extreme pressures. Open gear lubricants must be specially formulated to keep equipment operating at maximum efficiency. Whether you operate a ball mill, rod mill, breaker mill, or kiln, Lubrication Engineers Pyroshield® line of heavy-duty synthetic open gear lubricants can help protect your valuable equipment and keep it running harder and lasting longer. If you are interested in making your large open gears last longer, lowering the amount of lubricant you use, and reducing overall maintenance expenditures, then we have the solutions for you.

LE Open Gear Lubricants

After several years of proving the superiority of Pyroshield open gear lubricants, LE improved the formula, making it even better! The improved Pyroshield formula no longer contains any heavy metals or lead. LE also increased the film strength of the lubricants, making them easier to pump - particularly for automatic lubrication systems. Finally, LE raised the viscosity index, removing temperature-based fluctuations that would be seen during actual use.

Pyroshield meets or exceeds all relevant manufacturer specifications for open gear applications. It is providing reliable lubrication in coal power generation facilities, cement kilns, and metal and mineral mining operations all over the world. Pyroshield's ability to protect open gears from extreme pressures, heavy loads and high temperatures is virtually unequaled.

No shutdown required when converting open gears to Pyroshield

Pyroshield Family

Pyroshield does not require the equipment to be shut down during the conversion process. Even better, LE's certified independent consultants can be there to assist you during the conversion process. Pyroshield can be applied manually or through automatic spay systems and clings tenaciously to the gear. Pyroshield appears translucent in use, allowing for the visual inspection of the open gear.

Pyroshield contains Almasol

Almasol Powder

Almasol® is LE's proprietary solid film additive adding extreme heat stability, anti-wear protection and extreme pressure properties to Pyroshield products. Originally developed for use in the late 1950s, this soft, tan powder has been incorporated into many of LE's industrial lubricating oils and greases. Unlike molybdenum disulfide and other solids used in lubricants, Almasol will not build up on itself and adversely affect machine operation with close tolerances or create hard deposits that lead to housekeeping issues.
