Silca will last 20+ years, high pressure for tubulars, if it breaks you can buy replacement parts instead of a replacement pump.
+2 on the Silca. Lasts forever, widely available preplacement parts. Easy to get to high pressure. And its made with Colombus tubing so it has the the "steel is real" and the italian cache.
However, you do need to grease the gasket every decade or so.
