Quattroflow 5K Quaternary Diaphragm Pump All-in-One Technology

Minimal Particle Generation

The QF5k has no mechanical shafts, seals, or wetted rotating parts, helping to minimize particle generation and maintain total product containment without abrasion.


Designed for high flow stability at flow rates from 50 lph to 6000 lph, the Quattroflow 5k Multi-Use Pump comes in a stainless steel pump chamber design, available for Clean-In-Place/Steaming-In-Place (CIP/SIP) and with the ability to be autoclaved.

The QF5k is unique, featuring an enhanced venting to reduce the minimum flow rate required to remove entrapped air during priming. This pump design allows for the gentle, safe, and secure conveyance of aqueous solutions and biological products that are sensitive to shear force.

Flow rates: 50 – 6000 lph
Turndown ratio: 120:1
Multi-use configuration: Stainless steel pump chambers compatible with autoclave, clean-in-place (CIP) and sterilize-in-place (SIP) protocols
