Key Factors in Vacuum Pump Selection
Vacuum Level Requirements
It is essential to know the particular vacuum level for your application when choosing a vacuum pump. The magnitudes of this level, generally in Torr or pascals, play a large part in the selection of pump type. Processes have different vacuum level demands; for example. Purity requirements for vacuum are much higher in semiconductor processing than in the packaging of food. The exact requirements for you process vacuum requirements can ensure you do not select a pump that is not right for your application. Furthermore, by knowing at what vacuum pressure to hold, the pump can be properly sized to optimize efficiency vs quality.
Flow Rate Considerations
Flow rate is an important consideration when selecting a vacuum pump, and it tells you how quickly a pump can evacuate the air from a chamber, typically expressed in standard cubic feet per minute (CFM) or liters per second (L/s). It’s critical to match flow rate to vessel volume to avoid over or under-pumping, which can have a substantial effect on process efficiency. Modulating the flow rate based on the vessel size ensures a consistent vacuum level that's crucial for a variety of industrial applications. When flow rate is accurately matched to system requirements, productivity rises and waste of time and resources are minimized.
Chemical Compatibility
Vacuum Pump (Chemical Compatibility is also to be considered) Knowledge of the chemical compositions of the processing materials assists in selection of materials resistant to corrosion and thermal stability. Thus, the pump is not only safely operated, but no material decomposition is also caused. Good practice is to study a pump material data sheet to support claims of compatibility to avoid equipment failure and support a long life of safe operation.
Lubrication Needs
Whether or not a vacuum pump will need lubrication and what kind is crucial to long-term and efficient operation. Oil requiring pumps may be quieter, but need some occasional TLC. Oil vs grease lubricated depending on the design of pump and the application intended.
