Quattroflow pumps help eliminate particle generation.
The company arranged for a third-party test featuring a comparison between a Quattroflow QF150SU model pump and a peristaltic pump that was using a pharma-grade pumping hose. Both pumps performed an eight-hour continuous recirculation of a liquid through a 12μm filter at approximately 100 L/hr (26.4 gph).
Following the trial, an examination of the filter membranes showed that two Mio particles with sizes between 6.1 and 12.7μm were generated during the operation of the peristaltic pump.
But no identifiable particles were generated during the operation of the Quattroflow pump which left clear filter membrane pores.
Quattroflow single-use pumps also create a quicker production process for biopharmaceutical manufacturers.
Quattroflow says the results show its pumps help eliminate particle generation and subsequent contamination of the product and are suitable for optimizing the handling of expensive and/or sensitive liquids in biopharmaceutical-manufacturing operations.
It adds that the pumps also create a quicker production process for biopharmaceutical manufacturers, as well as delivering required levels of product purity and sterility with no corresponding harm to the product or cross-batch or cross-product contamination.
Other features include reduced downtime, low pulsation, consistent flow rate, quiet operation, self-priming and dry-running capabilities.
