Pfeiffer MVP 040-3

This Pfeiffer MVP 040-3 is a used diaphragm vacuum pump that has been removed from active laboratory service and checked over for continued operation. It is a dry running, oil free pump design that is widely used in analytical and laboratory settings where sample integrity matters and any risk of oil backstreaming into the process line has to be avoided. Because it uses a multi stage diaphragm mechanism, it delivers a clean, chemically resistant vacuum suitable for a wide range of gases and light vapors. Users rely on this pump family for tasks such as sample preparation, filtration, degassing, rotary evaporation support, and as a backing pump in front of turbomolecular pumps. Its small footprint and quiet operation make it a good fit for benchtop use in busy labs where multiple systems need dedicated low maintenance vacuum sources. The unit is compact enough to sit next to the instrument it supports without needing dedicated utility hookups beyond standard power. Being sold as a used unit, it shows normal cosmetic wear consistent with lab service but remains functional and ready to be integrated into a vacuum train or standalone application. It is a practical, budget friendly option for labs that need a reliable oil free backing or process pump without paying new equipment pricing.
