Dual-use vacuum pump

The dual-purpose vacuum pump alternately performs vacuum pumping and pressurization through mechanical means, utilizing the movement of internal pistons or diaphragms to change the chamber volume. It is used in coating testing for degassing, filtration, and liquid transfer.
Selection
When selecting, consider the required vacuum level and pressure range to match sample characteristics; focus on airtightness and corrosion-resistant materials; compare pumping speed with energy consumption; check interface compatibility and maintenance convenience.
