Centrifugal pump lubrication management
Thread Content
What brands and models of lubricants are used for chemical pumps in companies, and how often should they be replaced?
Mobil 46# Lubricating Machine Oil, 3 months
The range of centrifugal pumps is also very wide; specific models and brands require analysis based on individual circumstances.
Mobil, Kunlun, BP, Shell…
Different pump speeds and loads require different lubricants; it is usually necessary to replace the lubricant every 3–6 months, or to conduct a lubricant analysis and replace it based on the results of that analysis.
Why isn’t the Great Wall recommended? We use 46# Great Wall lubricant. :lol
The range of options available is actually quite wide. There is a significant difference between domestic lubricants and imported ones, and there is much room for improvement especially when it comes to the base oils!
Basically, 46# engine oil (mechanical lubricant) is the preferred choice; unless the rotation speed is particularly high, in which case 32# should be used, or if the rotation speed is particularly low, then 68# is appropriate. High temperatures also warrant the use of 68#, while low temperatures call for 32#. As for the brand to choose, it’s obviously best to opt for well-known brands
We can only say that we chose cost-effectiveness. Going further, it means showing patriotism by choosing domestic products. :lol
Big bro, I’m telling the truth, no lies!
