Agitator pump bit broken

[Goosey]

My chiller wasn't sending the cold water to the cooling jacket on my handpump so I took the pump apart and found this...
Has anyone got a spare or know where I could get one?

Your "agitator" will work. Just reassemble without the broken pump impeller and make sure you refit that red propeller (the "agitator").

Now fit a small pump anywhere in the cooling circuit (doesn't have to be in the cooler). The pump will need to be a self-primer type (cheap diaphragm pump will do). The pump doesn't need to be too strong, in fact a powerful pump might cause problems. That'll fix you up while you get a more "permanent" affair. You'll have to figure out how to power the pump and a diaphragm pump will effectively close the cooling circuit when stopped. Even if the impeller pump was working the pressure buildup in the closed circuit will be negligible. Watch out - the pressure buildup with a diaphragm pump won't be negligible! That's why they are "self-primers".



I'm looking at a similar setup ... the pumps in those coolers are pathetic!

Hallamshire Brewery Services do refurbishing and repairs, they may be able to source you a spare if you give them a ring?

I've actually just ordered a small aquarium pump that will fit between the coils inside the water bath. I don't see any reason why this won't do the same job. I can put a t-piece on the output to use as an agitator.

I've fitted the pump, a small aquarium pump for about 30€. It works perfectly. Absolutely silent too. I can't see why this shouldn't work just as well as the original pump.
