Hydraulic Oil

Hydraulic oil is a non-compressible fluid that is used to transfer power within hydraulic machinery and equipment. Otherwise known as hydraulic fluid, hydraulic oil can be synthetic- or mineral-based.

Although it is commonly used in the transfer of power, hydraulic fluid can act as a sealant, coolant and lubricant within machinery and equipment. Hydraulic oil can be used for Forklift Trucks ,Log Splitters ,Automotive Lifts ,Wright Standers . Snow Ploughs (Snow Plows) ,Skid Steers (Skid-steer Loader and Skidsteer) ,Aircraft (aviation) ,Air Tools ,Tractors ,Cruise Ships and the Marine Industry. Superior hydraulic oils are available in a wide range of ISO and SAE grades to meet these and many other critical machinery challenges, such as high speed , high pressure , high temperature , very low temperature in winter , turbine – grade temperature and those used for food processing and packaging are available .for a hydraulic oil to be useful it needs to have the below properties:

Non-compressible
Thermally stable, within a range of operating temperatures
Fire resistance
Non-corrosive & Anti-wearing to its system
Low tendency to cavitate
Tolerance to water (resistance to water contamination)
Total water rejection
Constant viscosity, regardless of temperature & Long Life

Generally speaking, hydraulic liquids are made up of Mineral oil , Esters , Glycol, Silicone, Ethers and some other chemicals .Different hydraulic fluid additives includes Anti-wear , Cold Flow ,Anti-foaming ,Anti-oxidant ,Anti-rust and anti – freeze

The classifications of hydraulic oil are a subgroup of different fluids with varying performance levels. Such as “

HL – Refined mineral oils with anti-oxidation and anti-rust properties
HM – HL with improved anti-wear properties
HR – HL oils with VI improvers

FAQ Hydraulic Oil

Hydraulic Oil is used to transmit hydraulic power while lubricating, cooling, sealing, and protecting pumps, valves, cylinders, motors, and other hydraulic system components.

The most commonly used grades include ISO VG 22, ISO VG 32, ISO VG 46, ISO VG 68, and ISO VG 100, with the correct grade depending on equipment design and operating conditions.

ISO VG 32 has a lower viscosity and is generally suitable for systems requiring easier fluid flow, while ISO VG 46 provides a higher viscosity and is widely used in general industrial hydraulic applications.

Anti-Wear Hydraulic Oil formulated with appropriate additive technology is commonly used in high-pressure systems because it provides improved protection against mechanical wear and helps maintain reliable lubrication.

Hydraulic Oil is commonly supplied in pails, plastic containers, steel drums, 200/208-liter barrels, IBC tanks, and bulk quantities depending on the customer's consumption and transportation requirements.

A practical way to find suitable Iranian Hydraulic Oil suppliers is through Irancorps, which helps buyers connect with Iranian manufacturers and exporters offering industrial products for B2B sourcing.
