Negative Pressure Vacuum Test Pump

Negative pressure vacuum test pumps mechanically extract air from sealed containers to create a vacuum environment, used to test material airtightness and packaging integrity. They simulate low-pressure conditions in the laboratory to verify product leak resistance, making them suitable for sealing tests on packaging bags, containers, and other items.
Selection
When selecting, consider the required vacuum range and its compatibility with the test item's volume, and pay attention to the corrosion resistance of the pump material. Check the pumping speed and the time required to achieve the target vacuum level, while also noting the equipment's operational noise and long-term stability. Choose an appropriate power rating based on the testing frequency, and balance this with ease of maintenance.
