Hello. Wonder if anyone can help me.
I have a Grundfos circulating pump on my combi. The pump was making a noise so i took the head off and saw that the impeller was warpd and catching. A new one will cost more money than i have to spare at the moment.
It is a grundfos 15-50 ao. have seen plenty of 15-50 grundfos selectric pumps on the net going relatively cheap can i swap the head of these with mine or the impeller.
Also have seen 15-50 ao b/bc advertised this looks close to mine aluminium head attached to a different pump body.
Also mine doesnt have a speed selection unlike the selectric. Does it have to have same energy rating.
Thanks Mike
