Are you talking about a floor pump? My pumps see Schraeder valves only rarely (last time was when the electric was out so I couldn't use the compressor to pump up the lawn tractor tires ) but I have no trouble at all getting 120 lbs out of my Serfas TCPG pump or my Specialized Air Tool Comp.

I do worry about gasket wear if a pump was used regularly for both types of valves. It always seems like the gasket is VERY VERY tight on Schraeder valves. But the Specialized pump is completely rebuildable.

Down south where we have hybrid commuter bikes, we have a cheap department store pump that does fine getting 65# into those tires, and I generally save the road pump for the high pressure Presta valve tires.
