Noisy Pump on Jobo CPA2

[tgtaylor]

For the past couple of runs the pump on the unit seemed much noisier than usual although the flow appeared normal. It started out noisy again today but quieted down during the run. Any idea of what this means?

Thanks

It means you need to lubricate the pump axle.
Remove the top cover and use spray oil to lubricate the SS axle. The pump motor has sealed SS bearings, that might be starting to fail, causing the axle to grind against the motor brace. That or corrosion on the axle is getting in the way and building up and breaking down.

Good luck.
