Quattroflow Releases QF2500 Quaternary Diaphragm Pump

June 14, 2020
The pump features a maximum flow rate of 2,500 lph (660 gph).

Quattroflow extends its line of multiple- and single-use pumps with the introduction of the new QF2500 Quaternary Diaphragm Pump. With a maximum flow rate of 2,500 lph (660 gph), the new QF2500 pump is suited to meet the needs of demanding biopharma applications including chromatography, TFF, virus filtration, sterile filtration and depth filtration. 

The Quattroflow QF2500 pump can excel in biopharma applications due to design enhancements such as a new pump chamber that provides excellent drainability to maximize product recovery. The QF2500 pump 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. Available accessories include a power box, diaphragm sensor and PID pressure controller.

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.
