Oberdorfer 2379 Impeller – OEM Pump Replacement Part
This is the genuine Oberdorfer 2379 impeller. Oberdorfer centrifugal pumps work by converting driver energy into velocity at the impeller and then into pressure in the volute, so impeller condition translates directly into delivered head and flow.
Measure delivered flow rather than trusting the sound of the pump. A drop in output at the same speed, a pump that struggles to prime, or a loss of pressure at the discharge all point at the impeller or at the clearance around it.
Check the clearance between impeller and volute or wear plate while the pump is open. A new impeller in a worn housing will not restore full output on its own.

Frequently Asked Questions
Q: How do I know the impeller is the problem and not the intake?
Check the strainer and suction line first. If the suction is clear and output is still down at normal speed, the impeller or its clearance is the likely cause.
Q: Should a wear plate be renewed at the same time?
Where the pump uses one, yes. Clearance is what makes the impeller effective, and a new impeller against a grooved plate gives back only part of the lost flow.
Q: Does it matter which way the pump turns?
Very much. Confirm rotation against the pump marking before start-up, especially after a motor has been changed.
Q: Is it worth keeping a spare aboard?
For any pump on a critical circuit, yes. An impeller is small, stores well and is not something you want to be sourcing away from the dock.
