Abstract: The Vacuum pumps used today are nearly the same as that those used 30 years ago, but with the new requirements of some special users it may be that we are entering a new area in pump evolution. The user demand for industrial types of application can be summarized as follows: reduced vibration and noise, increased reliability, handles large quantities of condensable or volatile gases, reduced oil consumption and costs in the use of expensive oil, reduced pollution caused by oil stream, corrosion resistance and oil free pumping systems etc. Those requirements force the pump manufacturers to change the characteristic of their products and research & develop new pumps.
Key words: Triplex Piston Pump; Vapor Handling Vacuum Systems; Roots Pumps on Clean or Corrosive Applications; Dry Screw Vacuum Pump
