Description
Castrol Anvol ™ SWX 46 FM and SWX 68 FM are HFDU Polyol ester type hydraulic fluids as defined by ISO
6734/4 and ISO 12922 (1). They are fully approved by FM Global (Factory Mutual) as industrial Fire Resistant
Hydraulic Fluids. The Anvol SWX FM range is outstanding in their category in providing a safe working
environment, improved system reliability and biodegradability.
Application
Formulated to work in high-pressure hydraulic systems up to 7500 psi. Anvol SWX FM provides gear, vane and
piston pumps with protection against wear equivalent to that of mineral oils.
Anvol SWX FM is designed to combine fire resistance with superior system reliability and a reduced tendency to
form varnish or sludge in valves, pipes and reservoirs. It also provides greater resistance to water by offering high
levels of corrosion protection. Even in the harshest steel mill environment, Anvol SWX provides safety, protection
and reliability. This has the added value of reducing failures and minimising unscheduled downtime.
Anvol SWX FM is used in areas of the manufacturing industry where there is high risk of fire such as hot strip
mills, coil handling facilities, pipe mills and continuous casters. The risk is minimized by Anvol SWX FM’s high fire
point and a low heat of combustion.
Anvol SWX FM fluids are compatible with Acrylonitrile-butadiene rubbers (NBR), hydrogenated NBR and
fluorocarbon rubbers (FKM). The Seal Compatibility Index (IP278) for Anvol SWX FM is comparable to mineral
oils.
Anvol SWX FM is classified as follows:
ISO 6743/4 - Hydraulic Oils Type HFDU
Anvol SWX FM grades meet the requirements (for appropriate viscosity grade) of:
Oilgear Towler
Bosch rexroth
FM Global 6930 Approved (FM Standard 6930 Jan 2002 Category 1)
Advantages
High fire point: provides superior fire resistance characteristics, creating a safer working environment and
greater equipment protection
•
Shear stable: maintains viscosity and fire resistant properties during use
Advanced corrosion inhibition: protects ferrous components from residual water and leads to extended
equipment life and reduced downtime
•
Excellent resistance to oxidation and thermal degradation: reduces sludge and varnish and prevents valve
sticking - ensuring longer system life and longer drain periods
•
Superior anti-wear performance: passes 12+ FZG stages and delivers excellent wear protection therefore
reduces downtime from unscheduled maintenance
•
Inherently biodegradable: well suited for applications where inadvertent environmental contamination
might occur due to leakage
•
(1) per ISO 6743/3 and ISO 12922: 1999 / Corrigendum 1: 2001 (E), these are classified as synthetic fluids free of
water, but of other composition than HFDR (Phosphate Ester)}.
