Multiple use stainless steel diaphragm pump for low flow rates with integrated controller.


The QF150S pharmaceutical pump is designed to offer a constant flow with low pulsation at low flow rates. It can pump a minimum of 1 liters per hour and pumps 180 liters every hour at maximum capacity. The four-piston pumping principle enables risk-free dry-running, low pulsation, self-priming, and minimal particle generation. Besides the stainless steel multiple-use version there is also a single use version available.

Quattroflow diaphragm pumps

Quattroflow stainless-steel Multiple-Use pumps deliver the highest level of purity, containment, and cleanability in biopharmaceutical-manufacturing operations, from simple product transfer to critical and demanding filtration and chromatography applications. Due to the pump mechanism, the pump can safely transport all liquids with a constant flow rate.

The quaternary piston design ensures that the product is completely contained without abrasion or particle formation. These sanitary pumps are suitable for CIP/SIP operations and also offer autoclaving capabilities.
