How to check the fit

  1. Match all wetted materials

    Check the fluid, concentration, temperature and solids against the fluid section, diaphragm and ball/check-valve materials. Matching port size alone does not establish chemical compatibility.

  2. Match connections and operating duty

    Confirm the thread or flange standard, required flow at discharge pressure, air supply and suction conditions. Maximum catalog flow is not the delivered flow at every operating point.

Selection & Installation

  • Confirm the complete part number and supplied revision before ordering.
  • Check fluid chemistry, concentration, temperature and solids against every wetted material.
  • Size the air supply and pump using the required flow at discharge pressure; maximum free flow is not the flow available at maximum pressure.
  • The manufacturer title identifies acetal checks, while its specification table lists Santoprene balls. Verify the exact assembly and repair kit rather than treating these as interchangeable.
