Diffusion Pumps

Because of its simplicity, high performance and low initial cost, the diffusion pump is the primary industrial high vacuum pumping mechanism. Agilent diffusion pumps offer high pumping speeds, high throughput, high tolerance forepressure, excellent backstreaming characteristics, low ultimate pressure, and long-term reliability. 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. The foreline ejector stage provides high tolerance for pressure and a large surface area for efficient degassing of compressed fluid, while the foreline baffle minimizes fluid loss, even under high throughput conditions
