Primary Fluid Systems begin in 1991, as two people building systems for local applications. Since that time, we have left system-building to the pros, and focused on what we do best: manufacture and sell metering pump accessories for a variety of industries. Our innovative and patented designs ensure that we provide the best product for your specific application.
