Quattroflow®, a brand of PSG®, a Dover company, and a leading brand of positive displacement quaternary diaphragm pumps, is pleased to announce that it has extended its single-use product line of quaternary (four-piston) diaphragm pumps with the introduction of the next-generation QF5kSU.

Automated pump monitoring systems bring a variety of benefits when used in biopharma liquid-processing operations. They can be used to optimize pump performance by giving the operator the ability to automatically control operational parameters while cutting back on the need for manual intervention. This control makes it easier to run simple process steps in biopharma applications more effectively, resulting in precise, consistent results without the need to dedicate time and effort to manual monitoring.

In this article, Glenn Hiroyasu, Americas development manager for Quattroflow Fluid Systems, examines the challenges of flow rate and pressure in chromatography, virus filtration, TFF and inline blending processes and illustrates why the quaternary diaphragm pump is ideal for use in biopharmaceutical-manufacturing applications.

Bei der Herstellung von Biopharmazeutika kommen Grundoperationen wie Chromatographie, Virusfiltration und Tangentialflussfiltration zum Einsatz, die jeweils einzigartige Anforderungen stellen. Allen gemeinsam ist, dass die Medien möglichst pulsations- und scherkraftfrei gefördert werden müssen. Ein Fall für 4-Kolben-Membranpumpen.

Biopharmaceutical manufacturing may come in a wide variety of forms, but every iteration of unit operation must adhere to an unbending set of operational parameters and structures if the desired outcome — a viable, contaminant-free drug suitable for human or animal administration — is to be realized. It is all about “controlled fluid transfer.”
