Dodgy Pump

[Stanios]

Found this odd pump inside a Halstead Ace combi..
No idea if the capacitor is meant to be like that, done all the tests on it and decided the reason the pump proving switch rod isnt going up is because of the diaphragm..
wrong! now thinking of replacing the pump even though the resistances are right :dizzy2:






So to sum it up pump proving rod isnt moving, if I force the switch the boiler fires then kettles but the pump has 200 ohms, 240v and the magnet gadget spins when its on.

Will appreciate any advice you guys can give

Blocked hex?

Blocked hex?

system water was clean when I drained the boiler, is there any other way of checking? Does that capacitor look right to you?

Just found this is a replacement capacitor from maplins..

But then why would magnet spin if the pump wasnt..

That's a rebadged Grunfoss, looks like an add on. Can you stop the pump with a screwdriver? If you can, it's shot.
Pump should look similar to this.

I've never tested a pump with a screwdriver, how do I go about doing it? Cheers

open up air port and jam an old screwdriver in if you cant stop pump fecked

Got plenty of old screwdrivers looks like have found some use for em!
I guess if the capacitor was shot the pump wouldnt even kick in so my magnet gadget wouldnt spin

I would just replace the pump.
