After you have finally decided the type of oven to use for your application, what comes next? Well, it’s time to pick the best pump to work with it. One of the most common options is the rotary vane pump. Choosing also means deciding between two major pumping technologies available: oil-free or lubricated pump. Take a deeper look at each one of these pumps to make your final selection.
As what the name suggests, an oil-free or oil-less rotary vane pump works without the need for lubrication. This makes it beneficial to use in the medical laboratories and related industries because of its cleaner results. With the absence of oil during pumping, there is no chance of product contamination. It is also less prone to wear and tear and may last up to two years or more of consistent use.
Plus, the oil-less pump needs low maintenance as it does not need oil changes but just a simple replacement of worn parts. Its biggest drawback is the price as it costs higher upfront than its lubricated counterpart. Yet, the cost is offset by lower operating cost without the need for lubrication.
On the other hand, the lubricated rotary vane pump has been around working hard in commercial and industrial settings. The oil used in this pump has varied purposes. First, it helps cool, seal, and lubricate the pump. This makes it a very efficient and effective option for those who are looking for an affordable yet durable pump. The greatest con of using this pump is the potential for contaminating the processed medium in cases such as plant extracts for medicines if not used properly. This is the main reason why lubricated rotary vane pumps are more opted for industrial applications where contamination caused by oil is not a big problem.
