Quattroflow™, part of PSG®, a Dover company and a leading brand of positive displacement quaternary diaphragm pumps, is pleased to announce that it has extended its multiple-use product line of quaternary (four-piston) diaphragm pumps with the introduction of the new QF5k. Incorporating a variety of critical design enhancements and offering a maximum flow rate of 6,000 lph, the QF5k is ideally suited for demanding biopharma applications such as chromatography, TFF, virus filtration, sterile filtration and depth filtration.

Quattroflow QF5k multiple-use pumps excel in biopharma applications thanks to an industry-leading design featuring pump chambers that provide drainability to maximize product recovery while significantly improving venting to remove entrapped air during priming. Available in four different drive versions, QF5k pumps were developed to meet a wide range of process requirements – from integration into fully automated systems to stand-alone applications that require their own pump controller.

Additional features and benefits of the QF5k pump include a proportional and linear flow performance for optimal precision during flow control; 120:1 turndown ratio; high flow stability even at low flow rates; low-pulsation characteristics; risk-free dry running; and clean-in-place (CIP)/steam-in-place (SIP) and autoclave capabilities. The QF5k model can also be integrated with the new Q-Control Integrated Pump Controller to provide users with automated control over their pump operations.

Quattroflow multiple-use pumps serve the biopharma industry that require gentle displacement, reliability, product safety, purity and cleanability. With the addition of the new QF5k, Quattroflow multiple-use pumps are now available in eight different sizes covering a flow range from 1 to 16,000 lph to meet the needs of small R&D projects to full-scale manufacturing environments.
