FAQ What is the primary advantage of using a Nitrile (NBR) diaphragm like the 97700045?Nitrile is an excellent general-purpose material known for its superior resistance to petroleum-based fluids, oils, fats, and greases. It offers a great balance of performance and cost-effectiveness for non-aggressive chemical applications. Can I use this 97700045 diaphragm as a replacement for a Santoprene or Hytrel diaphragm in my ARO pump?While it will physically fit in the same 1 inch PRO series pump, you must verify chemical compatibility. Nitrile is not suitable for ketones, halogenated hydrocarbons, or strong acids. Switching materials without checking your pumped fluid’s compatibility can lead to premature failure. What are the typical signs that my ARO pump diaphragm needs replacement?Common signs of a failing diaphragm include a noticeable drop in pump performance (flow rate or pressure), fluid leaking from the pump’s air exhaust, or visible cracks, stretching, or hardening of the diaphragm material during a visual inspection.
