ShinMaywa Norus Pumps Replacement Parts
The following replacement parts are available for ShinMaywa Norus Pumps, though the repair work takes a degree of expertise.
How to Know which Parts to Replace
- If your direct drive pump trips your outdoor GFI but does not make noise and runs fine when plugged into a non-GFI outlet, you probably need a rebuild kit. Your pump probably just needs fresh oil, gaskets, and O-rings.
- If your direct drive pump whirs or hesitates, but will start when you manually spin the impeller, your pump probably needs a capacitor.
- If your direct drive pump makes a grinding sound, it probably needs new bearings.
- If the shaft on your direct drive pump is stuck and doesn't move at all, you probably need a new pump.
Rebuild Kits
By request, we have put together rebuild kits containing the mechanical shaft seal, oil chamber upper & lower O-rings, oil gasket, and 12oz of oil. Please be advised that you can often reuse the current gaskets, and in that case all that you really need to rebuild a ShinMaywa pump is the mechanical shaft seal and oil.
