Hydraulic Oils

Petro-Florida manufactures and distributes various hydraulic fluids. We carry different grades of anti-wear hydraulic oils, biodegradable elevator fluid and many more. Delivery in Miami available.

General requirements and properties of hydraulic oil

Hydraulic oils (working fluids for hydraulic systems) are divided into petroleum, synthetic and water-glycol. By appointment, they are divided according to the scope of application:
for aircraft, mobile ground, river and marine equipment;
for hydro-braking and shock-absorptive devices of various machines;
for hydraulic drives, hydraulic transmissions and circulating oil systems of various units, machines and mechanisms that make up the equipment of industrial enterprises.

The hydraulic actuator can not operate without a liquid working medium, which is a necessary structural element of any hydraulic system.
In the constant improvement of hydraulic actuator designs, the following trends are noted:

increase in operating pressures and the associated expansion of the upper temperature limits for the operation of working fluids;
reducing the total mass of the drive or increasing the ratio of transmitted power to the mass, which causes more intensive operation of the working fluid;
reduction of working clearances between the parts of the working element (output and receiving cavities of the hydraulic system), which tightens the requirements for the cleanliness of the working fluid (or its filterability in the presence of filters in hydraulic systems).
In order to meet the requirements dictated by these trends in the development of hydraulic drives, modern working fluids (hydraulic oils) for them must have certain characteristics:
have an optimum level of viscosity and good viscosity-temperature properties over a wide range of temperatures, i.e. high viscosity index;
to have a high antioxidant potential, as well as thermal and chemical stability, which ensure a permanent permanent operation of the fluid in the hydraulic system;
protect hydraulic components from corrosion;
hydraulic oils must have good filterability;
have the necessary deaerating, demulsifying and anti-foam properties;
protect hydraulic components from wear and tear;
be compatible with hydraulic system materials.
Most mass grades of hydraulic oils are produced on the basis of well-purified base oils obtained from ordinary petroleum fractions using modern extraction and hydrocatalytic purification processes.
The physico-chemical and operational properties of modern hydraulic oils are significantly improved when they are introduced into them functional additives – antioxidant, anticorrosive, antiwear, antifoam, etc.
