The Quattroflow pump is a quaternary (4-piston) diaphragm low shear pump that enables 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.
Compared to Single Use centrifugal pumps, the Quattroflow pump does not generate any heat. Heat generation can largely impact cell viability in critical processes. The gentle operations of the Quattroflow pump is ideally suited for these sensitive applications.
Unlike the operation of a peristaltic pump, the gentle working principle of Quattroflow pumps has been specifically designed to help eliminate particle contamination of your product. This makes Quattroflow pumps ideally suited for optimizing the handling of expensive and/or sensitive liquids often found in a variety of biopharma applications.
If you are looking to replace permanent process pumps with single use pumps, reduce development costs, increase flexibility, and eliminate cleaning and validation requirements, ESI Ultrapure has the solution for you.
