Please send me a list of vacuum pump rotors (by pump model) that you manufacture along with price and delivery. I see where you list 'Customize CNC Machining SS stage rotor with shaft for Vacuum Pumps' and 'Customize CNC Machining 1st Stage Rotor for Rotary Vane Dual Stage Vacuum Pump' as products that you offer and we are interested in learning more about what you can provide for vacuum pumps. Thank you
