How Quattroflow™ Quaternary Diaphragm Pumps Work (French)


Quattroflow™ Quaternary Diaphragm Pumps are truly unique in that their method of operation mimics that of the human heart, which is the perfect model for the safe, reliable and efficient transfer of biological materials. The low-friction, low-shear and low-pulsation operation of Quattroflow pumps with minimal corresponding temperature increase makes them ideal for critical applications within biopharmaceutical manufacturing, including Tangential Flow Filtration (TFF), Chromatography (RFC), centrifuge feed, sterile virus filtration, purification and inline dilution. Quattroflow pumps can also be outfitted with a single-use liquid chamber, which enables them to meet strict speed-to-market manufacturing demands. For more information, please go to
