Quattroflow 4400 Quaternary
Diaphragm Pump
Application Note for the QF4400
A test performed on our Quattroflow 4400 Quaternary Diaphragm pump showed that the pressure pulsation measurements were in the range between 0.05 and 0.13 bars.
Minimal Particle Generation
The QF4400 has no mechanical shafts, seals, or wetted rotating parts, helping to minimize particle generation and maintain total product containment without abrasion.
Overview
Frequently used in mid-size crossflow systems and chromatography, the Quattroflow 4400 Single-Use and Multi-Use pumps offer a high 100:1 turn-down ratio, which is often a necessity for biopharmaceutical processes. Featuring four pistons, the design of this quaternary diaphragm pump allows for gentle, safe, and secure conveyance of aqueous solutions and biological products that are sensitive to shear force.
The Quattroflow 4400 pump possesses a flow rate of up to 83 lpm at 0 PSI. With its innovative design, this model can be utilized in research, pilot plants, or production facilities throughout the biopharma industry.
Flow rates: 0.83 - 83 lpm
Turndown ratio: 100:1
Single-use configuration: Single-use pump chambers can be supplied gamma irradiated or autoclaved
Multi-use configuration: Stainless steel pump chambers compatible with autoclave, clean-in-place (CIP), and sterilize-in-place (SIP) protocols
