Quattroflow QF30SU – Single-use diaphragm pump for ultra-low flow rates

The Quattroflow QF30SU extends the single-use range with an extremely low flow range of 0.06 – 30 l/h. It is designed for applications requiring very small capacities, such as process development and personalized medicine, as well as higher pressure applications including TFF and chromatography.

Thanks to its redesigned diaphragm, air removal and self-priming are optimized, resulting in very low pulsation and stable flow performance. The QF30SU is also suitable for long-term and continuous processes.

Key features
• Single-use pump chamber, quick replacement without tools
• Flow range 0.06 – 30 l/h, max. 4 bar
• 500:1 turndown ratio
• Linear flow performance
• Hose barb connections 4 mm (1/8” or 3.2 mm)
• Analog input 0–5 VDC
• Easy integration on a QF150 pump
• Accessories available (control box, diaphragm sensor, PID pressure controller)

Typical applications
Chromatography, TFF and virus filtration.

The QF30SU delivers precise low-flow control with high process stability for critical pharmaceutical and biotech applications.
