Good old scholl smoke system for pitts s2a

[hnivers]

I have an old smokesystem and the pump will not actuate when switched on. Will this pump, dont know its name or part number, but it is the one with a cup clamped beneath, be ruined running dry for too long. I noticed on an acro flight i had turned the switch on accidentaly with no oil present.
Any idea how to get a new one or a replacement?
