Quattroflow QF 30SU

Single-Use Pump for Low Flow Rates

The method of operation of Quattroflow pumps allows them to gently, safely and securely convey aqueous solutions and biological products that are sensitive to shear force. The four-piston design does not feature a mechanical shaft seal or wetted rotating parts, ensuring total product containment without abrasion or particle generation. Additionally, the four-piston pumping principle enables risk-free dry-running, low pulsation, self-priming and minimal particle generation.

Quattroflow has recently extended its Single-Use product line to the lower end. With a flow rate of 0.06 – 30 lph, the QF30 has been developed for very low needed capacities. This pump contains a disposable pump chamber with tool-free installation and is available with several accessories like a power box, diaphragm sensor and PID pressure controller. Its typical applications include: chromatography, TFF and virus filtration.
