Quaroflow Quaternary Diaphragm Pumps

The Quaroflow® displacement pump is based on the principle of the heart, 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 Quaroflow pump to gently, safely and securely convey shear-sensitive aqueous solutions and biologic products with minimal impact. The four-piston design does not include a mechanical shaft seal or wear-rotating parts, ensuring total product containment without abrasion.

Quaroflow® single-use and multiple-use four-piston diaphragm pumps meet all the operational requirements necessary to ensure the safe, cost-effective, efficient and reliable transfer of biological materials. This technology is clean-in-place (CIP) and sterilize-in-place (SIP) capable and includes disposable solutions that increase flexibility, reduce downtime, eliminate the costs associated with cleaning validation and decrease cross-contamination risks.
