Synthetic esters can be fully saturated partially saturated and unsaturated. Fire-Resistant Fluid Phosphate esters are the most fire resistant of the non-aqueous synthetic basestocks in common use.
When the possibility exists that a hydraulic fluid may come in contact with a source of ignition or the surface of very hot equipment fire-resistant fluids may be used.
Polyol ester hydraulic fluid. Hydraulic Fluid is available in two viscosity grades. ISO 46 and 68. It is formulated with synthetic polyol esters and select ashless additives to provide outstanding fire resistance and excellent lubrication and wear protection for hydraulic pumps and motors.
Polyol ester fluids offer good compatibility with system materials easy conversion from petroleum oil and excellent hydraulic fluid performance. In addition the organic nature of these fluids gives them good environmental performance in biodegradability and aquatic toxicity. Polyol ester fluids can cost more than twice as much as petroleum oil so they are still used primarily only when fire resistance or biodegradability are high priorities.
Other types of synthetic fire-resistant. Synthetic polyol ester fire resistant hydraulic fluid Can be used in or near fire hazards and in environmentally sensitive hydraulic applications For use in systems with a maximum operating temperature of 70C 150F in combination with partial refreshment by system leakage. DuBois offers multiple hydraulic fluid series formulated to reduce metal to metal contact increasing the life and efficacy of the hydraulic unit.
Our hydraulic fluids products are. Rust and oxidation inhibited. Oil polyol-ester and water glycol based.
Polyol ester fluids offer good compatibility with system materials easy conversion from petroleum oil and excellent hydraulic fluid performance. In addition the organic nature of these fluids gives them good environmental performance in biodegradability and aquatic toxicity. The polyol ester resulting from this condensation reaction can be blended with various additives to produce a biobasedbiodegradable hydraulic fluid with improved oxidation stability exceeding conventional petroleum formulations.
Synthetic esters can be fully saturated partially saturated and unsaturated. Cosmolubric HF Series Polyol Esters Chemically and thermally stable these fluids were designed for long dependable performance in areas where less flammable hydraulic fluids are used. Additive package delivers a unique combination of performance corrosion protection metal passivation hydrolytic stability and oxidation inhibition.
Although Phosphate Ester Fluids offer very good lubricity for hydraulic components extreme caution must be used when handling or discarding this type of fluid. Special seals and hoses must also be used on all of the hydraulic components within the hydraulic system. CMR properties of P-esters Polyol and PAG based Water free Fire Resistant Hydraulic Fluids HFDu can have a clear limit of residual fluid.
It has to be judged case by case Contact the local Quaker representative for assistance WATER BASED CONVERSION. Water-based fire resistant hydraulic fluids like water glycol HFC and invert emulsions HFB do. Only polyol esters have been found to satisfy this demanding application and incorporating even small amounts of diesters or PAOs will cause the lubricant to fail vital specificationsPolyol esters are also the ester of choice for blending with PAOs in passenger car motor oils.
Fire-Resistant Fluid Phosphate esters are the most fire resistant of the non-aqueous synthetic basestocks in common use. Their high ignition temperatures excellent oxidation stability and very low vapor pressures make them difficult to burn while their low heats of combustion result in self-extinguishing fluids. There are many types of ester based fluids and several are widely as used as lubricants as hydraulic fluids andor as lubricant additives.
Examples include phosphate esters diesters and polyol esters. These are used because they have performance andor safety advantages over just mineral oil based fluids. Synquench is a polyol ester base fire-resistant hydraulic fluid FRHF recommended for hydraulic applications where potential fire hazards exist.
For optimal performance these hydraulic fluids do not contain water mineral oil or phosphate ester but instead are derived from high quality synthetic organic esters and carefully selected additives. Both formulas provide fire-resistance premium lubrication and superb anti-wear properties. Syndustrial Hydraulic Fluid is formulated with synthetic polyol ester POE base oil and select ashless additives to provide excellent lubrication and wear protection for hydraulic pumps and motors.
O-ring compatibility chart offers guidance on chemical resistance and swell for Viton o-rings FFKM o-rings Silicone o-rings Teflon o-rings and more. O-ring compatibility plays a critical role in o-ring performance a find the right material for your application and avoid o-ring failures. Supports microbial growth iii Polyether Polyol -are non-aqueous 100 synthetic fire-resistant hydraulic fluids approved by FMRC as a less hazardous hydraulic fluid These products contain additives which provide rust and oxidation protection as well as superior anti-wear properties.
CosmolubricHF Series Polyol Esters HFDU CosmolubricHF Series fluids are synthetic polyol ester hydraulic fluids that are chemically and thermally stable. They are designed for long service life and dependable performance in areas where a less flammable hydraulic fluid is required. When the possibility exists that a hydraulic fluid may come in contact with a source of ignition or the surface of very hot equipment fire-resistant fluids may be used.
