PSG Biotech Quattroflow Diaphragm Pumps

Name: PSG Biotech Quattroflow Diaphragm Pumps
Brand: Getinge

Single-use & multi-use integrated smart pumps

Distributor Line: As part of HPNE’s partner portfolio, this product extends our ability to deliver complete and reliable bioprocessing solutions under Getinge.

The Quattroflow diaphragm pumps are utilized in biopharmaceutical processes such as chromatography and filtration; their seal-less design ensures the gentle transfer of shear-sensitive biologics, with disposable single-use options further eliminating the need for complex cleaning and sterilization between batches.

A gentle force in sterile pumping

Quattroflow pumps are purpose-built to ensure the integrity of high-value, shear-sensitive media across the bioprocessing workflow, making the Quattroflow technology critical for numerous upstream and downstream applications, including:

Filtration and separation, Tangential flow filtration: Recirculation of feed and retentate in membrane cassettes, hollow fiber, spiral wound, and ceramic elements.
Depth and sterile filtration: Serving as a gentle feed pump for filter cartridges and plate-and-frame depth filters.
Purification and metering
Chromatography: Precisely packing chromatography columns and consistent flow for separation processes.
General fluid transfer: as well as many other sensitive fluid transfers, recirculation, and metering applications.

PSG Biotech Quattroflow Diaphragm Pump family

Quattroflow diaphragm pump range

The Quattroflow portfolio offers an extensive flow capacity range, ensuring that a suitable, low-shear solution is available for all key stages of the bioprocessing workflow—from lab-scale development to full commercial production. Leveraging the proprietary four-piston diaphragm technology, each model delivers a gentle, highly reproducible, and linear flow, with minimal pulsation and a negligible risk of product contact with non-wetted parts. As shown in the table below, the range extends from micro-dosing precision to high-volume transfer, providing scalability and performance.
