Pumps Quaternary Diaphragm Pumps
Quattroflow has recently announced that it has extended its line of multiple- and single-use pumps with the introduction of the new QF2500 Quaternary Diaphragm Pump. With a maximum flow rate of 2,500 lph (660 gph), the new pump is ideally suited to meet the needs within demanding biopharma applications, including chromatography, TFF, virus filtration, sterile filtration, and depth filtration.
The Quattroflow QF2500 pump is able to excel in biopharma applications thanks to numerous design enhancements such as a new pump chamber that provides excellent drainability to maximise produce recovery, states the firm. The pump also features a self-draining design, 125:1 turndown ratio, high flow stability even at low flow rates, linear flow performance, and clean-in-place (CIP) capability. Available accessories include a power box, diaphragm sensor and PID pressure controller.
With the addition of the new diaphragm pump, the company’s pumps are now available in eight sizes covering a flow range from 0.06 to 16,000 lph (0.02 to 4,227 gph). The firm’s pumps primarily serve biopharma applications that require gentle displacement, reliability, product safety, purity and accuracy.
The design does not feature a mechanical shaft seal or wetted rotating parts, ensuring total product containment without abrasion.
Additionally, the pumping principle enables risk-free dry running, low pulsation, self-priming, and minimal particle generation, adds the company. With single- and multiple-use models available, the firm has a pump to fit every application need.
