The QF2500 Quaternary Diaphragm Pump from Quattroflow, part of PSG, a Dover company, extends the company’s range of pumps.
The QF2500 Quaternary Diaphragm Pump from Quattroflow, part of PSG, a Dover company, extends the company’s range of pumps. The pump has a maximum flow rate of 2500 lph (660 gph) to meet the needs of chromatography, tangential flow filtration, virus filtration, sterile filtration, and depth filtration applications.
The device features a new pump chamber, a self-draining design, a 125:1 turndown ratio, high flow stability, linear flow performance, and clean-in-place capabilities. Users can also add on a power box, diaphragm sensor, and PID pressure controller. With the addition of this pump, Quattro flow pumps are now available in eight sizes ranging from 0.06 to 16,000 lph (0.02 to 4227 gph). The design and pumping principle result in dry running, low pulsation, self-priming, and minimal particle generation.
