The Quattroflow QF20KSU single-use quaternary pump for biopharmaceutical processing reduces contamination risk and downtime.

Quattroflow, part of PSG, a Dover company, will introduce the new QF20KSU single-use pump at INTERPHEX in Booth No. 2253. The pump features replaceable polypropylene wetted pump chambers, which can be easily replaced as a complete unit between batches to eliminate sterilization, lower cross-product contamination risk, and reduce downtime. The QF20KSU features flow rates of 200–16,000 Lph (53–4227 gph), 51 mm (2 in.) connections, and autoclave and gamma irradiation capabilities.

Quattroflow QF1200-HT single- and multi-use pumps have a high turndown ratio for precise accuracy in controlling flow rates. Their compact design with integrated controller provides a plug-and-play solution for applications requiring precision flow control, quick batch changes, and a small footprint. The QF1200-HT offers flow rates of 6–1200 Lph (1.6–317 gph) and 19-mm (3/4 in.) connections.


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