  • Q:

    Could this pump head also be used in reverse mode (backwards direction) ?
    Asked on 12/4/2012 by Joe

    • STAFF EXPERT

      A:

      No, this will not pump in the reverse direction, there are valves in place to keep flow in a single direction.

  • Q:

    Can this pump head be used with drive model EW-07554-80. Also, can this pump head be used with very acidic (such as H2SO4) and very basic solutions?
    Asked on 10/14/2010 by Henry from Rochester, NY

    1 answer

    • STAFF EXPERT

      A:

      Yes, the pump head will work with the specified drive. PTFE is very chemically resistant. You can use our chemical compatibility database in the technical library on the website to check your basic/acidic solutions. PTFE is compatible with Sulfuric acid.
