Dirty water pump

[catlad]

I have a Stuart Turner supervort 140a p47240/5010/0426 part code 46541
That has slowly started loosing its power! on taking it apart I can see a plastic disk with a spiral on it that looks worn its about 3 1/2 inch in diameter .
I was wondering if it could be replaced? I looked on their website but I could not see anything about repairs.

The disc wont be worn, at new they deal with grey water and semi solids up to around 20mm and kick out around 100 litres per minute. Why do you believe it is down on power?

Hi Pumps
Thanks for the reply
The pump just got slower and slower to start up, like it can't break the initial inertia to start the water flowing.

Time for a replacement I think.

Agree with just pumps. I used to repair/service a lot of sub pumps and it sounds as though the electrical insulation on the internal windings may be breaking down due to intermittent shorts. They are not "user friendly" for diy repairs unless it is simply replacing an impeller. Yours unfortunately doesn't sound like a worn impeller.

Used to recon the bigger heavy burgers, rewinds and all.
