got a 1/2 inch ARO diaphragm pump that needs rebuilding, this the right kit for that?
Answer by: Customer Support on Apr 7, 2025, 6:43 AM
For a 1/2" ARO diaphragm pump, this is the service kit you want. It carries the ARO catalog number C1BW94 and comes from Ingersoll Rand ARO, so it's a proper fit for that pump size. The diaphragm material is neoprene, which is worth noting before you order since the material needs to match what your application is running through the pump.
