The Idea: Pump Follows Evolution
How can a pump be designed to convey extremely delicate biologically active molecules? The solution is in nature itself! Millions of years of evolution developed the perfect device to pump blood that contains albumin, gamma globulins, clotting factors and cells. It is the heart!
The Quattroflow® pump is based on this principle, featuring quaternary (four-piston) diaphragm technology that enables a gentle pumping through soft “heartbeats.” Each stroke of the four diaphragms is generated by an eccentric shaft, which is connected to the electric motor. This method of operation allows the Quattroflow pump to gently, safely and securely convey shear-sensitive aqueous solutions and biologic products with minimal impact.
The four-piston design of Quattroflow pumps also does not require a mechanical seal or wetted rotating parts, ensuring total product containment without abrasion and minimum particle generation. Additionally, the four-piston pumping principle provides risk-free dry running, low pulsation, self-priming and a high turndown ratio.
