The PS RO-F features a robust design with a rotating seal and multiple springs, making it suitable for ANSI Chemical Pumps. Built to resist high levels of corrosion, abrasive, and viscous fluids, this sturdy architecture also makes the balanced RO-F PTFE a reliable choice for high-pressure applications. Utilizing a simple, rugged open rotary design allows aggressive, abrasive, and viscous fluids to be sealed more easily compared to ANSI types that incorporate shrouded spring rotaries.
