Many pharmaceutical products require particular care when being transported during production. Tony Peters, managing director of AxFlow UK, looks at shear sensitive leak-free pumping with eccentric movement pumps.
Throughout many areas of pharmaceuticals and healthcare products there is a substantial requirement for pumps that are capable of handling shear-sensitive liquids as well as liquids that can have an adverse affect on mechanical seals. Often coupled with this is the need for such pumps to offer leak-free performance.
While many types of pump can accommodate some of these demands, the challenge for plant managers is to find one that ticks all the boxes. The oscillating eccentric piston pump principle, developed by Mouvex, goes a long way to address all these demands. The principle produces the pumping performance of a rotary positive displacement pump. However, its action is far more sensitive, making it ideally suited to applications where shear and potential leakage are major issues.
