Vacuum Ejector

 
 Vacuum Ejector Manufacturer in Ahmedabad, Vacuum Pumps Supplier

Principal of Jet vac units
High pressure motivating fluid is converted to high velocity. High velocity fluid entrains and transfers part of its momentum to the induced fluid. These mixed fluids at low velocity enter the diffuser, which is so shaped that it gradually converts's the velocity energy to pressure energy and discharges them to a pressure higher than suction pressure but lower than initial motivating fluid pressure.

 

 
Salient Features Matertial Of Construction
  • Absolute reliability.
  • Robust and long working life.
  • Can be made from many corrosion resistance material.
  • Easy handling even of large suction quantities.
  • low capital, installation and maintenance costs.
  • Compact and light weight.
  • No moving part to wear or to go out of order.
  • Simple in operation.
  • No sealing and lubricating liquids are required as in mechanical system as per eg:
    Water ring vacuum pumps & high vacuum pumps.
