Mingtian - Model MTRR Series -Two-Stage Tandem Roots Vacuum Pumps

For reasons of efficiency and temperature rise, the pressure ratio of single-stage vacuum pumps is generally limited to 2.2. To achieve higher pressure ratios, two vacuum pumps are usually connected in series to form a two-stage tandem vacuum pump. In this case, the two-stage tandem Roots vacuum pump requires spray water cooling.
