Product Description:

A diffusion pump works on the principle of gas diffusion to create vacuum. In a diffusion pump, diffusion pump oil is heated to its boiling temperature. Vapor of this oil is compressed in a vertically tapering hollow cone as it moves up. Simultaneously this oil vapor escapes from jets along the height of hollow cone. Oil vapor escaping at great speed traps air and then collides with water cooled wall of Diffusion Pump and moves down. Trapped air is released at bottom of Diffusion Pump. This creates differential pressure in diffusion pump. Pressure at top is minimum (high Vacuum) and at bottom is maximum (low Vacuum) from bottom of diffusion pump the air is sucked by rotary pump.

Diffusion Pump has been successfully made in rectangular shape also. In fact rectangular shaped Diffusion Pump has an advantage that its inlet connected to Vacuum Chamber can be of larger area and Diffusion Pump itself can be adjusted to occupy less space. This also works with Diffusion Pump Oil as a working medium just like cylindrical Diffusion Pump.

Application:

Vacuum coating : Multi-arc ion coating machine, Magnetron sputtering coating machine, Resistance evaporation coating machine, Electron beam evaporation optical coating machine, Rolling vacuum coating, Continuous vacuum coating machine production line /In-line coating production line, etc

Vacuum furnace:  vacuum soldering/brazing furnace, vacuum annealing furnace, vacuum tempering furnace, vacuum sintering furnace, vacuum carburizing furnace, etc

 

Other: electron, chemical industry, metallurgy, aviation, aerospace, material, creature medicine, atomic energy and universe probe, etc.
