Diffusion Pump
Diffusion Pump

Scientific & Analytical Instruments offers Diffusion Pumps designed and manufactured to suit the need of industrial and Laboratory applications. Main Body of these pumps is fabricated fro S.S. and Jet Assembly is manufactured from Aluminium / S.S. These Diffusion Pumps gives Higher pumping speed, low back streaming and achieve Vacuum upto 1 x 10-6 mbar with DC 704 Oil. Small Diffusion Pumps with 3' Port are Air cooled while all larger pumps are water cooled.

Principle of Operation

Pump fluid is heated in the boiler to produce a vapor which passes up through the interior of the jet assembly and emerges from the jets as high-velocity Vapour streams. The vapor streams condense on the cooled pump-body wall and drain into the boiler at the bottom of the pump for recirculation.

A portion of system gas which arrives at the Diffstak pump-inlet is trapped in the vapor stream from the first-stage jet. The gases are compressed and transferred to the next stage. This process is repeated through the pump jet-stages until the gases are removed by the backing pump through the cooled backing-condenser.

The fractionating feature of the Diffstak design provides a means of purging the fluid charge of undesirable light fractions and foreign matter and the process helps significantly towards the attainment of a low ultimate vacuum.

The ejector jet also purges the fluid of any contaminants as it returns to the boiler and at the same time ensures a high critical backing pressure even when you use low vapor pressure fluids.
