I started on my refurbishment of this 3/4 HP pool pump. Pump is a Dynamo, DYN 11-N1-3/4
Amazon still lists this, and mine is old. I see more powerful dynamo Pentair pumps for less on amazon.
Disassembled the whole thing, cleaned it all and painted the end bells.
Bearings are in good shape.
The air exposed pump shaft was rusty. I primed, painted, then greased and heat shrunk a rubber tube over that, so it will not be rusting again.
The armature, I disassembled the centrifugal switch, cleaned and put a coat of primer on exposed parts. If a motor sits a long time, it can rust armature to stator, and do not want that to happen on the boat.
I should have the pump together today and next week working on the boat.
I have cleaned up the motor housing and the bolt down foot I will coat with some PL to prevent rust, on top of the grey primer. Pump motor was black, I am painting it buff.
When kids were young, we had an above ground pool. I kept the pump and sand filter. Then my friend gave me his pump for his above ground pool, so I now have 2, but his needs a new impeller, which is maybe $25 I don't have to spend..
Impeller for the pump I am using in the boat is # 35-4552
For my purpose 3/4 HP, motors draws 9 amps, is plenty. Other pump is 1HP.
