ARO 637124-44 Fluid Service Kit, Polyurethane/PTFE
Fluid kit pairing a polyurethane diaphragm with PTFE balls, listed for the 1-1/2" ARO 66615A-344-C pump
ARO 637124-44 is a fluid section kit built around a polyurethane diaphragm and Teflon (PTFE) check balls. It is listed for the 66615A-344-C metallic pump.
The ARO 637124-44 kit renews the wetted side of an ARO (Ingersoll Rand) diaphragm pump. Its spec sheet lists a polyurethane diaphragm and Teflon/PTFE balls. The diaphragm moves fluid as it flexes, and the balls lift and reseat to act as check valves. Those are the parts that wear first in a fluid section.
Order by the full number, including the -44 suffix, so the diaphragm and ball materials match your pump. The product record does not list other kit contents.
When to Use This Kit
- Fluid leaks from the air exhaust, which can point to a torn diaphragm.
- Flow drops or the pump loses prime because the check balls no longer seal.
- The pump cycles but moves less fluid per stroke than it did when new.
