Diaphragm Vacuum Pumps in Pilot & Process Operations

Fri, 03/21/2014 - 3:12pm

Of the wide range of vacuum pump technologies used in the pharmaceutical and chemical process industries, many incorporate wetted materials that prove problematic because of poor corrosion resistance. Chemical-resistant diaphragm vacuum pumps, with their oil-free operation, can offer substantial long-term cost savings over pumps – such as oil-sealed rotary vane pumps – that are not as resistant to corrosive chemicals. Improved chemical resistance can provide cost savings through reduced maintenance, longer pump life, greater productivity, and lower operational costs. Significant advantages in process control can contribute further to operational efficiencies. This article reviews design features of diaphragm pumps which yield these benefits.
