The principle, application, and tangible result of diaphragm metering pump in liquid chlorine conveyance have been narrated in the article. The title pump ensures safety in F22 production.

To improve the cavitation performance of diaphragm metering pump, a comparison of cavitation test is made between the modified diaphragm metering pump and the original measuring pump.

Odorization pumps are specially designed diaphragm plunger metering pump, plunger travel of the exercise machine lock, each time to maintain a constant output.
