HYDRAULIC OIL

MGE-46V OIL FOR HYDROSTATIC DRIVES is produced in accordance with TU 38.001347–00 and is designed for hydraulic systems lubrication of agricultural and other machinery operating at pressure up to 35 MPa with short-term increase to 42 MPa.

Notes:

  1. During MGE‑46V oil production involving VNII NP‑357 wear inhibitor the norms for parameters in p.3 “Acid number” and p.10 “Corrosion tests” are specified “within range 0.5–1.5 mg KOH / 1 g of oil” and “max 2c” respectively
  2. For quality check of MGE‑46V oil OJSC “Naftan” performs acceptance tests for all parameters of table 1 except the following: “Kinematic viscosity at 0 °C” (p.1), “Oxidation stability” (p.9) and “Change in mass of grade UIM‑1 gum in MGE‑46V oil” (p.11), which are checked at regular intervals.
  3. “Density” parameter (p.12) is specified by OJSC “Naftan” only in case of oil supply to Russia.
