6/19 · 3. Working principle of automatic vacuum self-priming pump. The working principle of the full-automatic vacuum self-priming pump is that the vacuum pump starts automatically, when the water is pumped into the steam water separation tank on the top of the self-priming pump, after the floating ball of the liquid level sensor set inside floats up

In this application, vacuum pumps are used to maintain a prime in cooling water systems. Maintaining a prime allows water circulating pumps to maintain
