Single-Use Pulsation Dampener - DMP-7000
The DMP-7000 pulsation dampener is designed for single-use applications in the life sciences industries. 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, chromatography, depth filtration and Fill-Finish; 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.
DMP-7000 dampeners are manufactured with all-plastic wetted fluid path made of Polyurethane and PEEK that meet USP Class VI, USP 661.2, and USP 788 requirements. The molded design reduces shear and improves surface smoothness. Enables ~85% reduc on in peak to peak flow pulsation. Pressure rating to 90 psi (6 bar). Gamma stable to 50 kGy. Available for line sizes from 1/16” to 1” ID, and with hose barb or tri-clamp end connections
Principal of Operation -
Fluid enters the DMP-7000 pulsation dampener downstream of the positive displacement pump. Inside the dampener, a series of flexible polyurethane membraned chambers absorb the pulsation caused by the pump and stabilizes the downstream flow rate.ra ng to 90 psi (6 bar). Gamma stable to 50 kGy. Available for line sizes from 1/16” to 1” ID, and with hose barb or tri-clamp end connections
