FAQ

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.

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.

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.
