Quattroflow pumps are available in two variations: the cleanable Multiple-Use and the increasingly popular Single-Use pump.

Quattroflow stainless steel Multiple-Use pumps deliver the highest level of purity, containment and, perhaps most important, cleanability in biopharmaceutical-manufacturing operations. From simple product transfer to critical and demanding filtration and chromatography applications. These pumps are suitable for clean-in-place/steaming-in-place (CIP/SIP) operations, as well as offering autoclave capability.

Quattroflow Single-Use pumps combine convenience with the ability to save time and money by eliminating the cost of cleaning and decontamination. Gamma-irradiated upon request, these pumps ensure the integrity of your process and production output by providing the safe, clean and reliable transfer of your high purity process fluids.
