A new multiple-use pump for biopharmaceutical applications

| By Mary Page Bailey and Gerald Ondrey

New QF5k quaternary (four-piston) diaphragm pumps (photo) incorporate a variety of critical design enhancements and offer a maximum flowrate of 6,000 L/h, making them suited for demanding biopharmaceutical applications, such as chromatography, virus filtration, sterile filtration and depth filtration. QF5k pumps feature 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 include: a proportional and linear flow performance for optimal precision during flow control; 120:1 turndown ratio; high flow stability even at low flowrates; 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, part of PSG, a Dover company, Duisburg, Germany
