Oberdorfer 1840 Spring – OEM Pump Replacement Part
The 1840 is an Oberdorfer service component. Oberdorfer pumps are designed to be taken apart and rebuilt, which is why individual parts like this one stay available long after the pump was installed.
Oberdorfer rates its bronze pump range for clear lubricating and non-lubricating fluids in the pH 4 to 11 band, with flows to 175 GPM, differential pressures to 150 psig and suction lift to 20 feet depending on the model. Components are specified against that envelope rather than to a general standard.
Renew the seals and O-rings at any joint that is opened to reach this part. They cost very little alongside the labour of a second strip down.

Frequently Asked Questions
Q: How do I confirm this is the right part for my pump?
Match it against the parts breakdown for your pump model, and send a picture of the pump plate if you want it checked before you order.
Q: Are Oberdorfer parts worth fitting over a generic substitute?
On a pump built to close internal clearances, yes. A part that is dimensionally close will not hold the clearances the design depends on.
Q: Should anything else be replaced at the same time?
Renew any seal or O-ring disturbed in reaching this component, and inspect the shaft and bearing while the pump is open.
Q: Is it worth holding a spare aboard?
For a pump on a critical circuit, yes. Sourcing parts away from the dock is slow and expensive.
