Hydraulic oil VMGZ
hydraulic oils
Description
Oil VMGZ (ISO VG 15) hydraulic oil. Can be used as vsezezonnoe, workable from -40 ° C to + 50 ° C.
Oil VMGZ waxy low-viscosity mineral base generated by gidrokatalicheskogo process thickened polimetaakrilatnoy additive. It contains additives: anti-wear, antioxidant, antifoam. Designation according to GOST 17479.3-85 – MG-15-B
.
Applications
designed for hydraulic drive systems and hydraulic control road building, harvesting, handling vehicles and other machinery operating in the open air at temperatures in the working volume of oil from – 40 ° C to 50 ° C depending on the type of pump . For the northern regions of oil VMGZ recommended as all-season, for the average geographical area – as a winter
