Unlike peristaltic and lobe pumps, Quattroflow quaternary pumps utilize 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. In addition, these pumps are self-priming and provide safe dry-run operation and allow for clean-in-place (CIP), sterilize-in-place (SIP) and autoclave capabilities.

QF20kSU Single-Use pumps feature 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.

The company’s QF1200-HT Single- and Multiple-Use pumps feature 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.
