NOTE: 
1, Inside the table above, the main pump could be" ZJ" pump, or" ZJP" pump with overflow valve; when" ZJP" is as the main pump," Z" should be changed to" ZP" , " S" represents Water Ring Vacuum Pump, while" Y" does Liquld Ring Vacuum Pump. 
2, If Roots Vacuum Pump and Water(Liquid)Ring Pump are operated at 60Hz, the displacement should be increased to 1.2 times
