Watson-Marlow Bredel”s 520Di and 620Di dispensing pumps and Pumpsil, Pumpsil-D, and Bioprene tubing are a good fit for pharmaceutical applications. The 520/620 family of peristaltic pumps are designed for dosing and transferring of corrosive or sensitive fluids in sanitary environments. The pumps meet the requirements of filtration, fermentation, and dispensing applications, meeting full quality testing standards. The 520Di (pictured here) features inherent dispensing and dosing programming to handle delicate laboratory environments and support the accuracy required for filling lines in biotech and pharmaceutical production. The new 520 pumphead features a large swept volume with low friction stainless steel rollers. The pumphead’s large diameter track and low rotational speeds (0.1 RPM resolution) provide long tube life and gentle handling of shear sensitive fluids. The pumphead accepts eight different tubing materials and sizes up to 9.6 mm for flowrates ranging from four microliters/min up to 3.5 liters/min at 30 PSI. The 620 pumphead is capable of 4.8 GPM (18 liters/min) and pressures up to 60 PSI.
