Castrol Dual Range HV Hydraulic Fluids are exceptional multi-viscosity hydraulic fluids that provide proven anti-wear protection coupled with very shear stable polymers and anti-foam additives for a balanced package. An extreme load carrying capability is indicated where Castrol Dual Range HV Hydraulic Fluids pass the FZG Load carrying test at Stage 12. This outstanding performance provides the extra measure of protection required in high load applications such as hydrostatic transmissions and high speed/high pressure hydraulic circuits.
Castrol Dual Range HV Hydraulic Fluids’ high viscosity indexes and their low pour points ensure extra pump protection and efficiency in cold weather starts and provide needed viscosity protection at higher operating temperatures. The products are dyed purple to facilitate leak detection.
Features and Benefits
Very shear stable polymers provide universal applications under a wide range of ambient conditions.
- Excellent viscosity at operating temperatures (particularly under extreme conditions).
Less wear promotes longer equipment life and better productivity through maximum hydraulic system efficiency.
Excellent vane and piston pump performance that meets major hydraulic pump manufacturers’ requirements.
- Less failure of hydraulic circuits.
- Less equipment repair for long term trouble-free service
Outstanding hydrolytic stability provides additional protection against corrosion in the presence of water. Systems operate more efficiently, while reducing maintenance costs.
Exceptional oxidation and thermal stability provides resistant to thermal degradation in the presence of entrained air and catalyzing metals.
- Prevents the formation of sludge and varnish deposits during periods of extended high temperature operation.
Resistant to the formation of oxidation acids allowing longer pump life, less wear, less down time
