Oil-free Piston Vacuum Pump

Oil-free piston vacuum pumps change the volume of the pump chamber through the reciprocating motion of the piston to compress and discharge gas. Self-lubricating materials are used between the piston and cylinder, eliminating the need for lubricating oil. These pumps are suitable for applications requiring a clean vacuum environment, such as laboratory filtration and sample preparation, to prevent oil vapor contamination of samples.
Selection
Select the appropriate model based on the required vacuum level and pumping speed, and verify that the interface dimensions are compatible with the equipment. Consider the characteristics of the medium; for corrosive gases, choose materials with corrosion resistance. Environmental temperature affects the lifespan of seals, so special design considerations are necessary for high-temperature applications. Operating noise and vibration levels should be selected according to laboratory standards. Maintenance cycles and the ease of obtaining spare parts should also be taken into account.
