ARO 637140-CB Service Kit, Santoprene Diaphragm, Neoprene Balls
Santoprene diaphragm and Neoprene ball service kit, listed for the ARO 666053-0CB diaphragm pump
Service kit for the ARO 666053-0CB double diaphragm pump, combining a Santoprene diaphragm with Neoprene check balls for the fluid side.
The ARO 637140-CB is the CB variant of the 637140 service kit family. It pairs a Santoprene diaphragm with Neoprene balls. Our data lists it for the 666053-0CB pump.
Neoprene is a soft rubber, so the balls conform to their seats and close with a gentle seal. The Santoprene diaphragm handles the back-and-forth motion that moves fluid through the pump. The specs do not list the full kit contents, so compare it against your pump's parts list.
When to Use This Kit
- Soft balls have become out of round or torn and no longer hold a seal.
- The pump loses its prime overnight or needs repeated restarts.
- A diaphragm tear lets fluid escape through the air exhaust.
