Diffusion Pumps, Chevron-Baffle & Vacuum Valves

The Diffusion pump is known as a fluid entrainment pump and use a high speed jet of vapor to direct gas molecules in the pump throat down into the bottom of the pump and out the exhaust.
The oil vapor hits the water-cooled walls of the pump and cools as it runs down the sides of the pump. 
At the bottom of the pump, the pressure is high enough for the gas to be pumped out by a standard mechanical pump.

The diffusion pump is widely used in both industrial and research applications.

These Plants can be fabricated for electro-pneumatic, sequential or PLC operation. VICO has many years of experience in building Industrial Coaters that are running successfully all over the Country.
