What Is the best vacuum pump for my application?
There is no one vacuum pump that is best for all applications. However, there are some general guidelines to remember for your selection. Oil Lubricated Rotary Pumps are used in applications requiring fairly deep vacuum (< 1 mmHg) and pumping relatively clean gases (Air/N2). Oil lubricated pumps are available in Single stage & Dual stage depending on what vacuum level you need. Additionally, all the oil lubricated pumps are available in Belt drive or Direct drive configurations. Belt drive is preferred in applications where pump longevity and durability is desired because of the low pump rpm (<700 rpm) and their high oil holding capacity which also guards against premature wear from oil breakdown. Direct drive pumps are preferred because of their low cost, compactness and portability. Dry Vane pumps; are used when a pump is required that does not require lubricating oil because of the objection to oil vapor discharge from the pump and filling/disposal issues with oil.
