What are some things to consider when pumping 5000' below sea level?
(OP)
I'm used to pumping above sea level but I was called and asked a question what are some of the affects that would come into play at 5000' below sea level. In a mine.
Do you have to do anything special. Special pressure gauges? Motor problems to contend with or what?
Thanks

Do you mean to say you will be pumping up to the surface from 5000 feet or that you will be pumping at various elevations at the lower elevations.
More discriptive information is needed.

rate (gpm)
pressure or head

If you were to submerge the pump 30 feet below water level - here the pressure on the pump would be much higher, would you be concerned ???

Also that the temperature below will increase (if not cooled) and that the bearing temperature ambient will be higher. So larger bearing clearances may be needed along with high temperature grease should be considered.
I found this out through another source.
Thanks anyway for your feedback.

Ambient temperatures in an underground mine are dependent on a host of variables, including but not limited to: virgin rock temperature (VRT), airflows through the workings, age of the mine openings, air temperature on surface, "wetness" of the mine, cooling/refrigeration plant capacity (if used), diesel engine and electrical loads, production rates (tonnes mined per day), etc. Having said all that, I've been in plenty of mines at depths of 5000 feet (and deeper) and while it is warm, most mines are not unduly "hot". Most mining jurisdictions & mining companies maintain temperatures below about 26 Celsius (wet bulb); 80 Fahrenheit. Don't forget that people have to work in these environments.
