DRY RUNNING FOR CORROSIVE MEDIA
29 October 2012
According to Sterling Fluid Systems, effluent/abatement costs mean dryrunning designs of vacuum pump are increasingly the choice of vacuum generating machine in the pharmaceutical industry.
Corrosive gasses and vapours can only be handled by machines that offer universal compatibility.
Corrosion resistant metals and polymers provide a degree of protection, but can be susceptible to arduous thermal conditions within dry running vacuum pump technology. On the basis that machines specifically designed for reliable temperature control ensure that corrosive media remains in the vapour phase, ductile irons provide a good metallurgical solution.
Machines with a uniform temperature profile throughout offer the ability to control heat-accelerated degradation/polymerisation.
