Can anyone tell me the difference?
I cou8be wrong but I’m pretty sure thehp5535 replaced the ts 2021 pump in the line up. Basically the same pump but the hp has a roller bearing. Like I said I could be wrong but I think that’s the only difference

The HP5535 was formerly the TS2021-B the B meant forged brass manifold. The TS2021 has a nickel plated forged brass manifold which makes it better suited for upstreaming chemical.
