Varian VHS-6 NRC 0184 Rebuilt 6-Inch Diffusion Vacuum Pump Rebuilt Refurbished
This Varian VHS-6 NRC 0184 Rebuilt 6-Inch Diffusion Vacuum Pump Rebuilt Refurbished is used and has been rebuilt. Diffusion pumps are the primary industrial high vacuum pumping mechanism. The bulge contour in the Varian VHS-Series maintains lower pressure for the process and increases the gas captured. VHS pumps feature glass fill and drain assemblies for easy maintenance of pump fluid and continuous monitoring. Finned boilers increase the surface area which prolongs fluid life. The full fractionating design allows vaporized fluid to be fractionated in the boiler and jet assembly. Contamination and decomposition products are pumped away and only the purest vapor reaches the top jet, assuring highest speed and lowest backstreaming. This pump has been fully rebuilt, it was carefully cleaned and inspected. The heat and electrical components were replaced where needed, and it has been repainted.
