I have a tank wash customer that uses steam to heat the water, then runs through the pumps (6 of them). They are all General TS1011 with a hot packing and valve kit. These machines are all auto start / stop, so there is no bypass to heat the water further. They are running 170 degree water through these pumps for 2 shifts a day, and rebuild every 2 years. Most water heaters will, at best, make 140 degree water, so for a properly equipped pump, it shouldn't be a problem.
LCI, is that 42 fahrenheit or celcius? I thought Canadians use Celsius scale. That would make the water 116 degrees fahrenheit
