Due to efficiency and temperature rise and other reasons, the single-stage vacuum pump pressure ratio is generally limited to 2.2. In order to achieve a higher pressure ratio, two vacuum pumps are usually connected in series to form a two-stage series vacuum pump. Among them, the two-stage series Roots vacuum pump requires spray water cooling.
