VMGZ oil: characteristics, advantages, selection criteria

The Russian market of lubricants has consistently demonstrated a stable growth trend. At the same time, a significant share of turnover falls on products oriented to industrial operation in conditions of large temperature fluctuations and high loads. The VMGZ oil (extra-seasonal hydraulic thickened), which ensures the uninterrupted operation of machinery equipped with hydraulic drives, in regions of the Far East, Siberia and the Far North, takes a worthy place in this segment.

Application area

The purpose of VMGZ is the working environment for hydraulic systems (hydraulic pumps, hydraulic control, hydraulic drives) of drilling rigs, hoists, vehicles, agricultural machinery, logging and construction machines, industrial equipment. Manufacturers recommend using this type of oil in the middle zone of Russia at negative temperatures (it is understood that VMGZ hydraulic oil is used in outdoors technology) and northern regions (regardless of season).

A few words about manufacturers and technology

Among the leading Russian producers of off-season hydraulic thickened oil, there are four authoritative companies that have a worthy business reputation. These are Lukoil, Gazpromneft, Shintoil, TNK.

As the basic basis of the future final product, high-quality selective-purification oils with low sulfur content, obtained as a result of hydrocracking of petroleum fractions or deep dewaxing, are used. This basis is characterized by a minimum dynamic viscosity and a low pour point. The operational and physicochemical characteristics, which should be oil of VMGZ, are provided by the addition of an effective composition of functional additives (anticorrosive, anti-foam, anti-wear, antioxidant, etc.).

Specifications

The table shows the typical properties of the VMGZ oil. Characteristics may vary depending on the type and specificity of the product.

Benefits

Applying off-season hydraulic thickened oil during the operation of specialized machines and equipment, consumers get the opportunity:

• Protect against corrosion damage and mechanical wear of the hydraulic system parts;
• To ensure uninterrupted operation of equipment in a wide temperature range (from + 50 ° С to - 40 ° С);
• To start the hydraulic drive, bypassing the preheating phase;
• To minimize the need for oil change (including seasonal) due to the high indicators of chemical and antioxidant stability of VMGZ;
• Avoid due to the anti-foam properties of excessive losses of working fluid in the presence of an effective level of cooling and lubrication of surfaces, which is very important for such high-speed mechanisms as hydraulic systems.

Why is quality important?

Low-quality oil VMGZ can cause a number of problems. Among the most critical we will outline the following negative consequences:

• Increased contamination of the hydraulic system;
• Clogging of filters;
• Increased wear and corrosion of parts.

As a result, the equipment prematurely fails, there are risks associated with the downtime or shutdown of production, increasing maintenance costs.

How to choose a quality product?

For the consumer of such a product as VMGZ hydraulic oil , the characteristics play a primary role. However, the products of the same class, offered by various manufacturers of lubricants, have approximately the same technical parameters. This fact is due to the use of a similar base set of additives. At the same time, each company, striving to take a firm position in a tough competitive struggle, relies on certain important properties of the final product. For example, we can talk about anticorrosive or temperature (the limit of congestion and ignition) indicators.

Therefore, the rules that should be followed when choosing VMGZ oil can be formulated as follows:

• Carefully study the attached instructions, drawing attention to the product's compliance with generally accepted international standards (ISO, SAE).
• Do not rely solely on the price segment, the defining criterion should be the authority of the brand.

Successful choice and smooth operation of your equipment!
