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, minimal particle generation and a high turndown ratio.
