Diaphragm Vacuum Pumps

Laboratory diaphragm vacuum pumps are low maintenance generally have a much higher resistance to corrosion as they do not require oil or lubricant for operation. These vacuum pumps have a high resistance to chemicals by utilizing corrosion proof PTFE on all the wetted surfaces and can be used in applications such as solvent evaporation (with rotary evaporators or centrifugal evaporators), distillation, solid phase extraction and filtration.

Our Frequency Conversion Chemical Resistant Vacuum Systems are a new generation of intelligent vacuum technology, modular design, integrating variable frequency pumps and control units, compact design and light weight. It can adjust the speed of the diaphragm pump by frequency conversion motor and controller, control the vacuum pressure more accurately.
