There are two main raw materials for the production of lubricants:
• Lube base oil stock
• Additives

Process of Mixing and Blending of Base Oil with Additives produces final finished lubricant oil.

Lubricant oil is a type of petroleum product that is used to reduce friction between moving parts in machines and engines. Lubricating oil reduces overheating, scuffing, rubbing, and corrosion due to its special properties. Lubricants oil therefore helps in increasing the equipment lifetime, extending the use of valuable resources, improving fuel economy and ultimately reducing greenhouse gas emissions.


One of the products is base stock, which processed further, provides us with base oil. The base oil is the lubricant that is used to lubricate machines. This base oil needs to have certain chemicals called additives added to it to enhance its performance as a good lubricating agent. These additives together perform diverse functions but each additive has a specific use and together they give the lubricant its character. Depending on the engine the lubricants are to be used; the ratio of base oil to additives varies from 85:15 to 90:10.
BASE OILS: Base oil is highly refined crude oil or in some cases a synthetic composition and they account for roughly one present of the total output of petroleum products from crude. It is essentially a by-product obtained during the refining of crude and is obtained along with the heavier ends. Different operating conditions like moisture, dust, exposure to air, high/low temperature, high pressure, corrosion, etc. dictate which base oil and which additives should be used.

Unfiltered liquid enters the basket housing and passes down them.
Solids are retained inside of basket mesh which is removed when the unit is serviced.
Basket Filters and strainers are normally supplied with a spring arrangement at the top of the filter element.
This will ensure any type of bypass & confirm the position of the basket filter even in case of reverse flow.
A fluid bypass around the basket is prevented by an optional “O” ring seal between the basket rim and the housing inside diameter.
For base oil basket filter provided with 200-micron mesh and For blending vessel basket filter provided with 50-micron mesh
