In my heating system, I have a UPS32-80 attached to a very specific TEKMAR cast iron block. The pump makes a deafening noise so I bought a new UPS32-80 to replace it.
Unfortunately, the new UPS32-80 has a plastic impeller whose water inlet has a larger diameter which prevents the new pump from fitting into the cast block.
My idea is to change the impeller from the old (metallic) pump to the new one but I have no idea how to remove both impellers without damaging the pumps.
Does anyone know how it can be done? Does it require a special tool?
Thanks for your time and attention.
