Positive displacement pumps, such as diaphragm and peristaltic pumps, produce pulsations in the fluid. These pulsations can negatively impact single-use pharmaceutical production processes such as TFF and chromatography, which need tightly controlled flow rates and line pressures. Malema’s single-use dampeners reduce pulsation and variations in flow of critical biopharmaceutical media in processing and transfer applications.
Features:
Up to 95% reduction in peak to peak flow pulsation
Wetted fluid path made of Polyurethane and PEEK that meets USP Class VI, USP 661.2, and USP 788 requirements
Patent-pending single-use design eliminates pulsation of flow rate and line pressure
Gamma-stable to 50 kGy
Available for line sizes from 1/4” to 1” ID, and with hose barb or triclamp fluid connections
Pressure rating to 90 psi (6 bar)
