The Jabsco 2431-0000 is a genuine Jabsco half-thickness brass cam for Jabsco flexible (rubber) impeller pumps. It is the half version of the 934-0000 cam. The cam is the curved insert inside the pump body that bends the impeller blades as they pass, squeezing liquid out of the blade cavities toward the outlet port.
Cams wear and corrode over years of service, and a worn cam reduces the pressure and flow the pump can deliver. Replacing it during a rebuild, together with the impeller and wear plate, brings the pump back to its original performance. Always match the cam thickness and profile to your pump.

Frequently Asked Questions
Q: What does the cam do in a flexible impeller pump?
It narrows the space in part of the pump body, flexing the impeller blades to push liquid out toward the discharge port.
Q: How do I know my cam needs replacing?
Look for wear, pitting or corrosion on its curved face, or loose cam screws that have allowed leakage.
Q: Should the cam screw be sealed?
Follow the pump manual. Many pumps use sealant on the cam screw threads to prevent leaks.
Q: Can a full cam be used in place of a half cam?
No. The cam thickness must match the pump body and impeller width, so use the part listed for your pump.
