D-A PresurFlo Dielectric™ Blue, Amber & Gold hydraulic fluids are a premium quality, high viscosity indexviscosity indexThe viscosity index (VI) is an arbitrary, unit-less measure of a fluid's change in viscosity relative to temperature change. ... The lower the VI, the more the viscosity is affected by changes in temperature. The higher the VI, the more stable the viscosity remains over temperature fluctuations.https://en.wikipedia.org › wiki › Viscosity_indexViscosity index - Wikipedia, anti-wear hydraulic oil with high dielectric strength (40 kV) for use in electrical service equipment, such as cherry pickers.
What do you mean by hydraulic fluid?
Definition of hydraulic fluid : a fluid usually of low viscosity (as oil or glycerol but seldom water) used in a hydraulically operated mechanism hydraulic fluid in a brake cylinder.
What are the three types of hydraulic fluid?
- Petroleum-based or mineral-based fluids are the most widely used fluids today. ...
- Water-based fluids are used for fire-resistance due to their high-water content.
What are the different types of hydraulic fluid?
- Viscosity (ASTM D445-97) is the measure of a fluid's resistance to flow and shear. ...
- Viscosity Index (ASTM D2270) is how the viscosity of a fluid changes with a change in temperature.
Is AW 32 hydraulic oil dielectric?
The High Viscosity IndexViscosity IndexThe viscosity index (VI) is an arbitrary, unit-less measure of a fluid's change in viscosity relative to temperature change. ... The lower the VI, the more the viscosity is affected by changes in temperature. The higher the VI, the more stable the viscosity remains over temperature fluctuations.https://en.wikipedia.org › wiki › Viscosity_indexViscosity index - Wikipedia (HVI) products are for wide temperature application and have a typical dielectric strength of 35kV which makes them suitable for use as non conductive hydraulic fluids. HVI-32 and HVI-46 meet FMC Corporation recommendations for a high viscosity index hydraulic fluid.
Is ISO 32 and AW 32 the same?
AW 32 hydraulic fluids have an International Standards Viscosity Grade or ISO VG of 32. This is the thickness of the fluid tested at 40 degrees Celcius. ISO VG 32 has good cold weather flow capabilities and its thickness is equivalent to a SAE 10 weight lubricant.
What is AW ISO 32 hydraulic oil used for?
ISO 32, 46 and 68 grades are most commonly used for hydraulics with vane-, piston-, or gear-type pumps, especially where pressures exceed 1000 psi. They can also be used to lubricate lightly loaded reciprocating compressors.
Is all hydraulic oil non conductive?
The standard for hydraulic fluid in the industry is mineral oil, which is a dielectric medium that does not conduct electricity. ... They have much lower viscosity than oil, and there are several fluid power application considerations as a result, but water-glycol mixtures, like bio-oils, are electrically conductive.Nov 15, 2017
Gard™ Non-Conductive Hydraulic Fluid is a stabilized non-zinc ashless anti-wear hydraulic fluid developed to meet the requirements of systems which operate in the vicinity of electrical applications. This oil is formulated to meet all basic industry standards of outside and industrial oils of this type.
