Techflow QT80-1

[kkelly77]

I'm trying to find a service manual for a TechFlow QT80-1 twin ended, positive head pump.

I'm currently stripping one to try and find the fault so I can order parts from TechFlow but running into difficulty as to how to get the pump apart.

I have both end covers off and have found some small plastic remains at one end. The impellers seem to be in good shape so I'm not sure what is the source of the plastic shards. Are there specialist tools needed to get the washers, springs etc off the motor spline?

have you phoned techflow? 01444 258017 for technical helpline.

No. I'm in the RoI, so calls would be pricey.

Do they offer helpline support to out of warranty pumps?

Just went back to the pump there and, after drying out a bit, the problem is pretty obvious. Looks like one of the impellers was grinding into the housing for some reason. I've attached a few photos.


Could this be because the retaining bolt on the plastic housing was over tightened? The housing/impeller on the other end of the pump is fine and yet is put together in exactly the same way.
