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 *0Hz, the displacement should be increased to 1.2 times.
