Quattroflow™ Quaternary Diaphragm Pumps Protect Sensitive Biological Media Better Than Competing Alternatives


Quattroflow™ develops and manufactures, in close cooperation with our customers, quaternary (four-piston) diaphragm pumps specifically designed for critical applications in the biopharma as well as food and beverage industries. The Quattroflow™ pump’s method of operation allows it to gently, safely and securely convey aqueous solutions and biological products that are shear sensitive. The four-piston design does not include a mechanical shaft seal or wetted rotating parts, ensuring total product containment without abrasion. Additionally, the four-piston pumping principle enables risk-free dry running, low pulsation, self-priming, and minimal particle generation. Quattroflow™ pumps are available with cleanable multiple-use stainless steel or disposable single-use plastic pump chambers.
