Oberdorfer 930G Self-Priming Pump – 3" Replacement Part
The Oberdorfer 930G is a complete pump with 3" porting. Oberdorfer builds its bronze pumps from corrosion resistant castings with stainless steel shafts and fasteners, which is why they last as long as they do in seawater.
Bronze construction is what makes these pumps suit raw water. Seawater will find any weakness in a ferrous casting within a season, and the stainless shaft and fasteners remove the other common corrosion path.
Support the pipework independently so the ports do not carry the weight of the run, and check rotation before the first start.

Frequently Asked Questions
Q: Does it need a strainer on the intake?
On raw water, yes. Sand and shell drawn through the pump shortens seal and impeller life more than anything else you can control.
Q: Can it be mounted in any orientation?
Check the model before deciding. Several in this range are specified for horizontal mounting, and orientation affects priming as well as bearing life.
Q: What decides how often it needs service?
Hours, water quality and whether it has ever been run dry. Watch delivered flow and the shaft area for weeping rather than working to a fixed interval.
Q: Are spare parts available separately?
Yes. The wear components are supplied individually and in kit form, so the pump is rebuilt rather than discarded.
