Quattroflow™ Single- and Multiple-Use Pumps on Display at INTERPHEX 2017

by PSG | Feb 28, 2017, Germany – February 28, 2017 – Quattroflow, part of PSG®, a Dover company and a leading brand of positive displacement quaternary diaphragm pumps, has announced that it will be showcasing its Single- and Multiple-Use pumps specifically designed for biopharmaceutical applications in booth 2253 at the upcoming INTERPHEX 2017. Taking place from March 21-23 in New York, NY, USA, the INTERPHEX event brings together a wide variety of leaders from the pharmaceutical and biotech industries.

At this year’s show, Quattroflow will be featuring its QF20kSU Single-Use pump that features replaceable polypropylene wetted pump chambers, which can be easily and quickly replaced as a complete unit between batches to eliminate sterilization, lower cross-product contamination risk and reduce downtime. This design also assists in optimizing speed-to-market to maximize product availability within its patent window. The QF20kSU features flow rates of 200 - 16,000 lph (53 - 4,227 gph), 51 mm (2”) connections, and autoclave and gamma irradiation capabilities.

Also on display will be the Quattroflow QF1200-HT Single- and Multiple-Use pumps featuring a high turndown ratio for extremely precise accuracy in controlling flow rates. Their versatile compact design with integrated controller provides a high performance plug- and-play solution for applications requiring precision flow control, quick batch changes and a small footprint. The QF1200-HT offers flow rates of 6 - 1,200 lph (1.6 - 317 gph) and 19 mm (3/4”) connections.

Quattroflow pumps are utilized throughout the biopharmaceutical and biotech industries in a wide range of applications requiring gentle product handling, high containment, low pulsation, purity and cleanability. Unlike peristaltic and lobe pumps, Quattroflow quaternary pumps utilize no moving parts to provide nonslip operation, which is optimal for transferring shear-sensitive products without damage while virtually eliminating particle generation and heat degradation. In addition, Quattroflow pumps are self-priming and provide safe dry-run operation and allow for clean-in-place (CIP), sterilize-in-place (SIP) and autoclave capabilities.
