Quattroflow 20K Quaternary Diaphragm Pump Minimal Particle Generation

Minimal Particle Generation

The QF20k has no mechanical shafts, seals, or wetted rotating parts, helping to minimize particle generation and maintain total product containment without abrasion.


The Quattroflow 20k Single-Use and Multi-Use Pumps are ideal for a range of biopharma applications, from research and pilot plants to production facilities. Featuring a flow range of 20 – 360 L/min @ 0 PSI, the design allows for higher flow rates and features an integrated controller for manual operation.

This pump was constructed to be state of the art and is extremely reliable. Mainly used to pump water-like fluids, the Quattroflow 20k pump was created to fit perfectly into your bioprocess, with both stainless steel and disposable single-use options available.

Flow rates: 20 – 360 L/min
Turndown ratio: 16:1
Single-use configuration: Single-use pump chambers can be supplied gamma irradiated or autoclaved
