Technical informationsPARAMO HMISO VG 22, 32, 46, 68, 100 HYDRAULIC OILS FOR HEAVILY LOADED HYDROSTATIC SYSTEMS
PARAMO HM are high quality hydraulic oils of HM class.
The base, highly refined oils used in this product are produced by means of a special hydrogenation technology.
They contain admix-tures containing anti-oxidation, anti-corrosion, anti-wear and anti-foaming additives.
They also contain additives that enhance low-temperature properties and viscosity-temperature dependence
These oils are designed especially for high pressure hydrostatic systems equipped with hydro-generators that impose high requirements on the anti-abrasion effects (lamella, axial and radial-piston types) and thermo-oxidative stabili-ty of the oil.
They also can be used in mobile hydraulic sys-tems working in all-season mode in non-protected enviroment, for luricating of loaded circulation systems, gear-type transmissions etc. Another application of this hydraulic oils is „oil mist“ lubricating.
The typical applications of the individual viscosi-ty categories of these oils are:PARAMO HM 22 – systems operated in very low temperature conditions (especially winter operations)
PARAMO HM 32 – systems operated in low temperature conditions (winter, all-season ope-rations)
PARAMO HM 68 – systems operated in regular conditions (mainly summer operations)
PARAMO HM 100 – systems operated in ex-tremly high temperatures, special aplications Classification, specification: ISO 6743/4HMDIN 51 502 HDIN 51 524 part II HLP CETOP RP91H ISO TC 28/SC 4 Characteristic properties:
•excelent anti-wear protection of lubricated systems
