In last post we talked about the multiple uses of lab vacuum pump, and we also discussed how to select a suitable lab vacuum pump for your rotary evaporator. Today we’ll go on this chemistry vacuum pump topic on how to protect your lab vacuum pump during use?
The first thing to remember is keeping out liquids and particulates. A chemistry vacuum pump is used to move air, gas or vapor, there are corrosive vapors that may do harm to the surface of lab vacuum pump, if you are working with corrosive gases or vapors, you’d better choose a lab vacuum pump whose surface is resistant to those corrosive mediums. At this time, a oil-sealed chemistry vacuum pump is not a good choice, because pump oil will also be polluted by corrosive vapor and gas, it will affect its performance of lubricating and sealing. More importantly, if oil is polluted by corrosive materials, it require lab vacuum pump operators change pump oil regularly.
So how to overcome the difficulty? Don’t worry, a hybrid vacuum pump can solve this. The hybrid lab vacuum pump combines a diaphragm pump with a rotary vane pump, in this cases, the chemical resisting diaphragm pump is used to keep oil under vacuum and the rotary vane chemistry vacuum pump is used to achieve fine vacuum degree. How does it work? The vacuum constantly distills corrosive contaminants out of the oil, extending service intervals by as much as 10 times. More advanced technology with more expansive cost, but it brings user less maintenance and service costs.
Another important thing on protecting your lab vacuum pump is keeping the pump oil clean. A diaphragm chemistry vacuum pump is no need oil, free of oil pollution.
