What oil is compatible with Hy-Gard?

Low-Viscosity Hy-Gard and Hy-Gard are compatible with hydrostatic oil and can be added to systems that contain hydrostatic oil.

What grade oil is best for hydraulics?

Hydraulic equipment used indoors under normal service conditions generally use a conventional antiwear hydraulic oil with the appropriate viscosity. The most commonly used viscosities are ISO 32, 46, or 68, since these are able to lubricate and protect the system under the normal range of operating temperatures.

What oil is compatible with Hy-Gard? – Related Questions

What happens if hydraulic oil is too thick?

A thick oil can damage the hydraulic pump, leading to breakdowns in the worst cases. The solution is to use lower-viscosity products. These ensure a reliable start also during the cold season, they lubricate better and maintain their performance over time.

Does it matter which hydraulic oil I use?

Viscosity is THE single most important factor when selecting a hydraulic fluid. It doesn’t matter how good the other properties of the oil are, if the viscosity grade is not correctly matched to the operating temperature range of the hydraulic system, maximum component life will not be achieved.

What does 68 mean in hydraulic oil?

The designation HLP 68 comes from the letter code “HLP” of hydraulic fluids according to DIN 51524-2 and the number “68”, which refers to the standardized ISO VG class. These are hydraulic oils with anti-ageing and anti-corrosion additives as well as active agents for reducing friction and wear.

Can you mix ISO 46 and ISO 68 hydraulic oil?

Mixing oils with different additive packages is never recommended. Doing so could compromise the additive performance of both constituents, cause corrosion of component surfaces and lead to increased mechanical wear.

What is ISO 68 oil equivalent?

Obviously, SAE and ISO use two different scales to measure viscosity. SAE 10W is equivalent to ISO 32, SAE 20 is equivalent to ISO 46 and 68, and SAE 30 is equivalent to ISO 100.

Is hydraulic oil better 32 or 46?

AW-32 is neither “better nor worse” than AW-46. The numbers refer only to the viscosity, not to the quality. Quality of the oil is determined by the manufacturer. For Atlas above ground lifts, AW-32 (lower number than AW-46) will flow “better” in colder weather than AW-46.

Can you use 15w40 for hydraulic oil?

Product Description. Mobil Agri Super™ 15W-40 is a high performance, multi-functional lubricant for most farm equipment applications. This STOU lubricant provides good performance in diesel and gasoline engines, transmissions, hydraulics, final drives and oil-immersed brakes operating in agricultural service.

What is the difference between ISO 68 and AW 68 hydraulic oil?

AW 68 hydraulic fluids have an International Standards Viscosity Grade or ISO VG of 68. This is the thickness of the fluid tested at 40 degrees Celsius. ISO VG 68 is on the heavier side for a hydraulic fluid which flows equivalent to a SAE 20 weight lubricant.

What does Aw stand for on hydraulic oil?

AW stands for anti-wear. These are RO hydraulic oils with an anti-wear additive package. The ISO classification for these oils is HM. MV stands for multi-viscosity.

What does the W stand for in hydraulic oil?

The W stands for winter not weight and there is a standard called the SAE Viscosity Grades for Engine Oils – SAE J300. To label multi-viscosity oil 10W-30 or any of the other multi-viscosity grades, the oil must conform to stringent test parameters performed at low temperatures and high temperatures.

What does ISO stand for in hydraulic oil?

ISO VG stands for “International Standards Organization Viscosity Grade” and is reported in numbers ranging from 2 all the way up to 1500. This number is critical because a lubricant’s viscosity is the single most important factor when selecting the right oil for your machinery.

Can you mix different weights of hydraulic oil?

As far as possible, it is always best to avoid mixing different hydraulic fluids. This is because the technical properties could be spoiled by chemical reactions between different additives.

What is the difference between 22 and 32 hydraulic oil?

ISO 22 Hydraulic Oil – ISO VG 22 Hydraulic Fluid is generally used in airlines for air tools etc. ISO 32 Hydraulic Oil – ISO VG 32 Hydraulic Fluid is ideal for use in high-powered machine tools. ISO 46 Hydraulic Oil – ISO VG 46 Hydraulic Fluid is normally required for industrial plant working under high-pressure etc.

Is ISO 46 the same as AW 46?

The quality of the base oil controls corrosion, oxidation, and suppresses foam and aeration. AW 46 hydraulic fluids have an International Standards Viscosity Grade or ISO VG of 46. This is the thickness of the fluid tested at 40 degrees Celsius.

What does 46 mean in hydraulic oil?

Now to the numbers: 22, 46 and 315 refer to the viscosity grade (VG) of the oil; 22 and 46 are ISO grades and refer to the oil’s kinematic viscosity in centistokes at 40 degrees Celsius, plus or minus 10 percent. So, an ISO VG 46 hydraulic oil has a viscosity of between 41.4 and 50.6 centistokes at 40 degrees Celsius.
