Dilex Supreme Hydraulic Fluid with DYNAVIS® is a premium, para-synthetic, multi-grade, anti-wear hydraulic fluid designed for year round use in high pressure hydraulic systems of mobile equipment. These systems require an MIL-H-5606 type hydraulic fluid that can operate over a wide range of ambient temperatures. Dilex Supreme Hydraulic Fluid with DYNAVIS® is recommended in hydraulic applications where protection against the formation of varnish deposits on close clearance servo-valves and other system components is critical and in applications that require the use of a high dielectric strength oil.
Typical applications in which Dilex Supreme Hydraulic Fluid With Dynavis® would be used include:
#275SW has a dielectric strength of 43 kilovolts which exceeds the OSHA minimum requirement 30 kilovolts for use in the hydraulic systems of mobile equipment used for repair and service of electrical lines.
It is blended from the finest quality polyalphaolefin (PAO), synthetic base fluids and petroleum base fluids available. This unique combination provides the Dilex Supreme Hydraulic Fluid With Dynavis® with the following advantages:
Blended into this unique combination of (PAO) and petroleum base is a highly specialized performance additive package and an extremely shear stable type viscosity index improver.
The highly specialized performance additive package provides Dilex Supreme Hydraulic Fluid With Dynavis® with the following performance benefits:
The extremely shear stable polymer viscosity index improver provides with a viscosity index of 292. This extremely high viscosity index allows Dilex to exhibit low temperature viscometrics that permit pumps to be safely started at low ambient temperatures where the flow properties of a conventional straight grade hydraulic fluids might cause problems. Conversely, when the hydraulic equipment reaches operating temperature or is exposed to high ambient temperatures, the high viscosity index of Dilex Supreme Hydraulic Fluid With Dynavis® allows the product to exhibit the proper viscosity needed in order to minimize internal pump leakage and wear.
The trend among hydraulic pump builders is to make their units more compact by employing higher system pressures and higher pump speeds. This often results in conditions of thin film lubrication that can result in excessive pump wear.
To prevent this wear, a hydraulic fluid must contain and effective anti-wear additive package. Though #275SW contains an exceptional anti-wear additive package that lasts longer than most conventional anti-wear additive packages found in conventional hydraulic oils, this exceptional anti-wear package will also disappear over a period of time.
To fortify these anti-wear capabilities of #275SW, Micron Moly® is further blended into the product. Micron Moly® is a liquid soluble type moly that plates itself to the sliding and rubbing surfaces of the hydraulic system. This plating action forms a long lasting solid lubricant film that is able to withstand pressures up to 500,000 pounds per square inch.
Once plated to the sliding and rubbing surfaces, Micron Moly® not only produces a smooth finished surface, but also reduces friction between moving parts. This results in less heat being generated, which in turn reduces operating temperatures and downtime.
