Providing Precision Lubricants and Lubrication Solutions



What are
"Precision Lubricants?"

The phrase “precision lubricant” is intended to have two primary meanings. The first meaning is in regards to the actual product itself as a “precision” product: the way in which it is manufactured and formulated. The second implies an application focus in the sense of a “precise” lubricant for a "precise" application.

1) Lubricants as a “precision” product:

When it comes to lubricants, there are basic oils and greases and then there are "precision" oils and greases.  The main difference between the two lies in the chemistry of the formulations including the quality of the base stocks, the additives, and the specific sequences in which the final product is manufactured including the timing of sequences, the temperature, and the requirements of the final product.

Here at Davley Darmex, the success of our particular products do not lie in any single ingredient or exotic new substance. Rather, it is the process of creating a product with the right combination of components, base fluids and additives, and then combining them successfully through exclusive production methods that give specific products their unique performance characteristics. Where lesser substitutes might have two or three basic additives, a fully-formulated Davley Darmex precision lubricant might have as many as fifteen or twenty additives in very specific amounts and combinations.


This is the "precision" of the product.

At Davley Darmex, our focus on the application is what drives the need for "precise" products.  Our strength lies in the fact that we have a tremendous range of products covering a broad spectrum of applications.  The advantage to you, as the customer, is the ability to choose a product at a price which allows you to maximize the benefit for your purchasing dollar versus the level of protection you require. 

Typical benefits from our products generally include:

• Extreme temperature protection (-90°C to 350°C)

• Excellent boundary lubrication

• Extreme pressure, load, and anti-wear characteristics

• Superior chemical, thermal and oxidation stability

• Very low pour-points, low coefficients of friction

• High film strength, high flash / fire points

• High viscosity indexes

• Superior rust and corrosion protection

• Excellent surface and shear stability

• Compatibility with metal / nonmetal components and other lubricating products

• Excellent water, saltwater, washout and steam resistance

• Non-drip formulas that resist fling

• User and environmentally friendly products

• A full range of food-grade and non-toxic products that meet NSF International guidelines and are fully compliant with Canadian and American Food Inspection Agency requirements where incidental contact is possible under Sections 21 CFR 178.3570 and 774.1 D78.


Example:  Hydraulic Applications.

Let's consider an example to better illustrate what we mean by "precise" lubricants for "precise" applications. 

RPL-G1050:  RPL-G1050 is one of our multi-purpose oils formulated from a mineral base stock with a broad additive package that is suitable for a wide range of typical plant operations including, among other things, basic lubrication for low demand hydraulic applications. It has the advantage of being an excellent choice as a general plant oil since it can be used in a wide variety of applications.  It is economically priced and will out-perform conventional multi-purpose oils thanks to the quality of the base oil stocks and the careful blending of choice additives.  For low demand hydraulic applications, this is an excellent product.

RPL-HY11LT:  Now consider the RPL-HY11LT, a much more pricey hydraulic oil alternative, which is a very careful and deliberate blend of 100% synthetic base stocks and specific additives for heavy-duty, extreme hydraulic applications across a wide temperature range and then boosted with anti-wear, rust and corrosion inhibitors for added performance.  It is designed to handle severe low temperature applications with ambient temperatures as low as -75°C (-60°F).  It has a high viscosity index to ensure that, as the oil reaches operating temperatures,  it maintains viscosity to protect critical applications in continuous periods of operation.  It also has an extremely low pour-point for easy flow in cold temperatures. 
Both of these products are “hydraulic oils” in the simplest sense, but they are completely different products.  Does this make one better than the other?  Not necessarily.  It just means that one is more suited than the other at certain times and for certain applications. A "precise" product for a "precise" application.

When it comes to  choosing a lubricant , the really difficult part is deciding when one product is more appropriate than another, especially when they are both technically in the same product category such as "hydraulic oils."


This is where the second half of our philosophy shines: “Lubrication Solutions.”
