Unlike the operation of a peristaltic pump, the gentle working principle of Quattroflow® diaphragm pumps has been specifically designed to help eliminate particle contamination of your product. This makes Quattroflow® diaphragm pumps ideally suited for optimizing the handling of expensive and/or sensitive liquids often found in a variety of biopharma applications.
To help verify the ability of our pumps to minimize particle generation, we commissioned a third-party test that featured a comparison between a Quattroflow® QF150SU model pump and a peristaltic pump. After the test was completed, an examination of the filter membranes showed that 2 Mio particles with sizes between 6.1 and 12.7 µm were generated during the operation of the peristaltic pump. Conversely, no identifiable particles were generated during the operation of the Quattroflow® pump.
In addition to the particle generation concerns mentioned above, there are additional disadvantages inherent in peristaltic pumps that could potentially threaten the quality of your process and final product, including:
