Quattroflow, part of PSG, a Dover company, has introduced the new QF2500 quaternary diaphragm pump designed for demanding biopharma applications, including chromatography, TFF, virus filtration, sterile filtration, and depth filtration.

The Quattroflow QF2500 pump has a maximum flow rate of 2,500 lph (660 gph) and a new pump chamber that provides high levels of drainability to maximise produce recovery. It also features a self-draining design, 125:1 turndown ratio, high flow stability even at low flow rates, linear flow performance, and clean-in-place (CIP) capability.

With the addition of the new QF2500, Quattroflow pumps are now available in eight sizes covering a flow range from 0.06 to 16,000 lph (0.02 to 4,227 gph). Quattroflow pumps primarily serve biopharma applications that require gentle displacement, reliability, product safety, purity and accuracy.

The Quattroflow design does not feature a mechanical shaft seal or wetted rotating parts, ensuring total product containment without abrasion. Additionally, the pumping principle enables risk-free dry running, low pulsation, self-priming, and minimal particle generation.
