most water cooling systems have inline gauges that either report back as a fan RPM or provide a visual showing water is flowing. Since the Pump on the H50 uses a 3 pin power off the MB fan header it will provide "RPM" feedback that can be seen on any program that monitors your system fans.
Most cases water pumps fail they just fail, they usually don't gradually get worse. with that being the case its hard to develop a sensor network that will let you know if the pump is failing. best thing that can be done is to keep all things equal and if you start seeing higher temps with no change in any thing else (making sure to keep same ambient and work load temps and fan configuration and flow) you may have a problem. with the accuracy of programs and the temp sensors them selves I would give a 1-2*C of margin.
