We replaced the pump motor by an brushless motor. We had similar lifespan and shorter. Additional the original pump wasted lots of energy in wear.
We also changed the insulation of the freezer to modern vacum boards. Before the freezer compressor was 24 h on, due to poor insulatin. Now we got up to 1.5 h a day to keep it cool.
We also changed the fridge and freezer temperature controll to microcontroller.
Was a hell of a work.

We have flojet 32601 -0092 Quad series pump r4105512a. ( 12v, 1.5 A max, 1.6 gpm 6.1 lpm, 50 psi 3.4 max) installed onboard as circulation pump for fridges/freezer.
They are relatively easy to source.
We have previously replaced ours and have recently put the spare in service.
They seem to run for about 14months before the brushes wear out (more precisely, the springs on the brushes hit the backstops, brushes still having plenty of material). The pump can be dismantled and refurbished.
* For those running the same model, have you noticed similar lifespan?
* Has anyone installed an alternative model for longer service?
We weren’t expecting to have to replace them this often, and the brushes don’t seem to be available from the vendor for repair.
This may have already been addressed in a previous topic but we couldn’t locate the thread.
