For harsh processing applications, Model 520RE high-pressure chemical metering peristaltic pump offers flows of 55 gph at 30 psi to 7 gph at 100 psi. It covers range of applications including low shear feed for contamination-free transfer of acids, bases, and slurries found in chemical-based industries. With repeatability at 99.5%, self-priming pump can accommodate flow rates from 0.1 µL to 350 gpm, and can withstand pressures up to 232 psi.
