Safety Fluid ESO-B
ISO 32
Product code: 0270.57
Biodegradable fire-resistant hydraulic fluid based on organic esters (HFDU category) with self-extinguishing properties and with anti-wear, antioxidant and antifoam additives. It is recommended where petroleum based lubricants present risks of accidental fire caused by hose burst or liquid spillage.

PAKELO SAFETY FLUID ESO-B ISO 32 is a fully synthetic fluid based on organic esters and it is formulated with specifically selected additives.
It is a product classified as “fire-resistant” with self-extinguishing properties.

PAKELO SAFETY FLUID ESO-B ISO 32 is more than 90% biodegradable according to test
CEC-A-33-T93.
When dispersed in the atmosphere, under the action of micro-organisms and of atmospheric agents, it generates non-toxic decomposition products until the final transformation in carbon dioxide and water.
If compared to conventional mineral oils, the product presents higher flash points and fire points.
Furthermore in case of accidental contact with flames or incandescent surfaces it avoids violent or explosive ignitions.

PAKELO SAFETY FLUID ESO-B ISO 32 has Very High and enduring natural Viscosity Index; the fluid guarantees minimum viscosity changes when it is exposed to different operating temperatures.

The product presents very low pour point, excellent anti-wear, anti-oxidative, anti-rust and antifoam properties.
It is compatible with metals and seals normally used in combination with mineral oils.
Regarding the general toxicological profile it is considered as not harmful.

Main characteristics are:

–  high ‘fire-resistance’ that means higher safety for workers and less risks of fire.

–  biodegradability (environmental pollution absence in case of spilling in the ground or water).

–  low toxicity of the products of combustion and smoke.

–  excellent lubricant and anti-wear properties.

–  great anti-rust properties.

PAKELO SAFETY FLUID ESO-B ISO 32 has good anti-oxidative properties and therefore it can also resist to significant thermal variations.
However it is suggested to maintain the product in good clean conditions and to not work with temperatures above 70°C (with peaks up to 90°C, for short periods), for the maximum oil drain interval.

Respecting the above indicated working conditions, the drain interval is the same one used in case of mineral hydraulic oils.
In the case of heavy duty conditions we suggest to reduce drain interval.
In any case, periodic oil analyses are strongly recommended.

Procedure for use

Before using PAKELO SAFETY FLUID ESO-B ISO 32 consider if a different chemistry type of hydraulic fluid (mineral oil, phosphoric ester or fluid as water-glycol or inverted emulsion) has been previously used.

–  in case of mineral oil
The product is miscible and compatible with mineral oils: therefore it is sufficient to drain the oil and to fill with PAKELO SAFETY FLUID ESO-B ISO 32. In the case of presence of sludge and varnish, it is necessary a preventive washing with the product itself. Filters have to be cleaned or changed.

–  in case of phosphoric ester
PAKELO SAFETY FLUID ESO-B ISO 32 results perfectly compatible and miscible with phosphoric ester: it will be enough to drain the circuit and to fill with the product. Any preventive cleaning operation it is necessary just in case of dirty circuit. Filters have to be cleaned or changed.

–  in case of water-glycol or inverted emulsion
The product is not miscible and/or compatible with fluids containing water: therefore it is necessary to completely remove the present fluid, before filling with PAKELO SAFETY FLUID ESO-B ISO 32.
However we advise to realize preventive washing of circuit with the product itself. Filters have to be cleaned or changed.

Compatibility with elastomers and materials

PAKELO SAFETY FLUID ESO-B ISO 32 does not affect ferrous materials, yellow metal alloys, antifriction materials, filters and seals normally used in hydraulic systems.
It guarantees effective anti-wear protection for pumps and all lubricated devices.
It is compatible with elastomers as Viton®, Teflon®, Buna N, Neoprene, Polyurethanes.

Fields of application

The product is particularly suitable for use in hydraulic systems operating in dangerous conditions (presence of flames or local extremely high temperatures) and where it is necessary to reduce as much as possible risks of accidental fire caused by hose burst or liquid spillage.

PAKELO SAFETY FLUID ESO-B ISO 32 is therefore indicated for oil hydraulic drive in iron industry (furnaces, rolling mill, etc.)
Moreover the product can be also used in hydraulic systems of operating machines (in alternative to mineral oils, to phosphoric ester, fluid as “water-glycol” and “inverted emulsion” type) considering warnings described above.

Quality Levels

The particular formulation allows the product, in the Viscosity Grade ISO 46, to satisfy severe Factory Mutual Research classification.
FMR is a universally recognized American organisation which certifies fire resistance level and “unflammability” of fluids.

Moreover the product belongs to fire-resistant hydraulic fluids HFDU category, in agreement with
DIN 51502 and VDMA 24317 regulations.
