Discflo in the Pharmaceuticals Industry
Disc pumps are unique in that they do not use centrifugal force or positive displacement. Instead, they operate on the boundary layer/viscous drag forces that produce a laminar flow with no pulsation.

This is significant for two reasons. First, laminar flow conditions provide the best protection for shear-sensitive and delicate pharmaceutical products. Non-impingement and laminar flow pumping has almost zero impact on the product. Second, laminar flow means lower NPSHr. Disc Pumps have NPSH requirements that are about half to a third of that required by conventional pumps plus the curve is stable through to shut off.

Disc Pumps have proven ideal for a range of pharmaceutical applications, including centrifuge feed, crystal slurries, solvents, emulsions, filter press, abrasive slurries and thixotropic and/or dilatant fluids.
