Vacuum Pumping Sytem

Roots vacuum pumps, or vacuum boosters, are dry vacuum pumps that are used together with backing pumps in a wide range of applications where large pumping speeds are required. Vacuum boosters operate completely contact-free and without sealing fluids such as oil or water in the working chamber, although with most models the two gearwheels of the synchromesh gearing and the bearings for the impeller shafts are lubricated with oil. Some roots vacuum / booster pumps are equipped with a by-pass valve.

Diffusion Pumping system consist of Diffstac type oil diffusion pump, Rotary vane vacuum pump as backinig pump . Liquid Nitrogen  Trap, Control pannel, mounting stracture & skid. For vacuum measerement Dital/Analog  Pirani & panning gauge are used.

Vacuum pumping system (VPS-FD-RD)
A vacuum pump is a device that removes gas molecules from a sealed volume in order to leave behind a partial vacuum. The first vacuum pump was invented in 1650 by Otto von Guericke, and was preceded by the suction pump, which dates to antiquity.
