The Grundfos Monsoon has a mechanical seal (see data Sheet)and gives a 5 year warranty, the Salamander, a 3 year, don't know about the seal.

Rubber lip seals.

All the ones I have seen have been on salamander domestic units.

Had a body burst on the cheaper stuart turner models as well.

With the pump running with a closed head and because of the check valves then there must be a potential for very excessive pressures due to expansion of the trapped water which is getting hotter.

Maybe no check valve on pump inlet though.
