Quattroflow® has extended its single-use product line of quaternary (four-piston) diaphragm pumps with the introduction of the QF5kSU. Incorporating a patented valve plate design that improves drainability and venting, the QF5kSU reduces the required minimum flow rate needed to remove entrapped air during priming, while providing enhanced product-recovery capabilities, and a maximum flow rate of 6,000 lph. The QF5kSU is suited for demanding biopharma applications, such as chromatography, TFF, virus filtration, sterile filtration, and depth filtration.
Additional features and benefits of the QF5kSU 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; and risk-free dry running. The QF5kSU model can also be integrated with the Q-Control Integrated Pump Controller to provide users with automated control over pump operations. Available in four different drive versions, QF5kSU pumps were developed to meet a wide range of process requirements – from integration into fully automated systems, to stand-alone applications that require a pump controller.
Quattroflow single-use pumps feature disposable wetted plastic pump chambers that can be replaced as a complete unit, eliminating the risks associated with cross-batch contamination. With the addition of the new QF5kSU, Quattroflow single-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.
