What is the difference between ISO 46 and ISO 32 hydraulic oil?

What is the difference between ISO 46 and ISO 32 hydraulic oil?

The hotter the temperature, the thinner the oil becomes and the colder the oil, the thicker. So, for example, a hydraulic system operating in a cold climate like Tasmania would run better with a lower viscosity grade of 32. Here in Perth, 46 and 68 are better suited to our climate.

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.

What is the difference between ISO 32 and AW 32 hydraulic oil?

Is ISO 32 hydraulic oil the same as AW 32? ISO 32 is simply a viscosity range for industrial oils, normally used in hydraulics, it says nothing about any additives that may be present. AW 32 is required to contain anti wear agents, it may also contain other additives, but may be harmful in certain applications.

What is the difference between ISO 46 and AW 46 hydraulic oil?

ISO 46 simply refers to proximity. AW stands for anti-wear. AW ISO 46 hydraulic oil is the same as AW46. Only the words are in a different order.

Can you mix ISO 32 and ISO 46 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’s the difference between ISO and AW hydraulic oil?

The ISO classification for these oils is HL. AW stands for anti-wear – R&O oils with an anti-wear additive package. The ISO classification for these oils is HM. The ISO classification is HR for VI-improved R&O oils and HV for VI-improved AW oils.

What is AW 46 hydraulic oil used for?

For example, AW 46 hydraulic oil is used to operate the hydraulic systems in off road equipment such as dump trucks, excavators, and backhoes, while AW 32 hydraulic oil colder weather application, like in a snow plow’s pump.

Can you mix different hydraulic oils?

CAN I MIX HYDRAULIC FLUIDS? 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.

Is VG 46 the same as AW 46?

AW 46 Hydraulic Oils contain a zinc anti-wear additive that is designed to protect hydraulic systems and equipment by reducing wear. 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.

Which is thicker AW32 or AW46?

What is thicker AW32 or AW46? AW32 is a little lighter than AW46. I would use the lighter weight if I was using it mainly in winter and the heavier if I was using it mainly in summer.

Is aw the same as ISO?

AW stands for anti-wear – R&O oils with an anti-wear additive package. The ISO classification for these oils is HM. The ISO classification is HR for VI-improved R&O oils and HV for VI-improved AW oils.
