MOL Hydro HM 46 AL

ashless hydraulic oil

MOL Hydro HM 46 AL is a high quality hydraulic fluid containing ash-free antiwear additives and carefully selected quality mineral base oil, which ensure consistently high performance even in hydraulic systems operated under heavy load conditions. It ensures outstanding wear resistance. In the standard vane pump test (Vickers V104C), the wear is 90 % lower than the specified limit. This product has an outstanding thermal and hydrolytic stability. Its TOST lifetime is 2.5 times greater than that specified in the DIN 51524-Part 2 standard. Its balanced additive system does not contain zinc, calcium or silicon compounds. The product meets the requirements of the Denison HF-O specification, which sets one of the highest level of performance for mineral oil based hydraulic fluids.

Applications

Hydraulic systems operating at high pressures and under heavy operating conditions
Industrial equipment operating at low temperatures (pumps, servo systems)
Hydraulic systems of machine-tools
Circulation systems
Hydraulic systems of machines used in the plastics industry
Turbo-, screw and vane compressors
Hydraulic systems of earthmoving and forestry machines

Product features	Benefits
Outstanding wear protection	Reliable long-term operation, even in equipment exposed to heavy loads at high pressures Anti-wear performance close to that of gear oils (FZG 12) Long equipment lifetime
Ashless formulation	Low deposit formation
Outstanding thermal and hydrolytic stability	Provides stick-free operation of servo and control valves Very low deposit formation tendency Reliable operation, so reduced operational costs Extra long oil drain interval
Excellent water separation	Water is rapidly separated from the oil and can be drained from the system The formation of harmful deposits and filter plugging can be avoided Longer oil change interval and equipment lifetime
Outstanding filterability	Calculably low filter usage even with 2-3 micron pore size filter cartridges No deterioration of filterability, even in the presence of moisture
Rapid air release together with low foaming	Reduced risk of cavitation Stable balanced lubricating film between friction surfaces, giving long equipment lifetimes
Excellent corrosion protection	Effective protection of steel and non-ferrous metal parts even in the presence of water
Zinc-free additive system	Reduced environmental impact when the product is ingressed into wastewater
