"Industrial" covers building services and manufacturing as opposed to mining, mineral processing, municipal, pharma, petrochem and nuclear.
End suction pumps are very common in all industries.
Municipal tends to use horizontal split case running at 4 pole motor speed because of a historical view tha slow running pumps cost less to maintain because they last longer.
If a full cost benefit analysis is performed it may work out that a 2 pole speed pump, with its smaller frame (& components) works out to have a lower total life cycle cost. Also need to take into account the real estate used for the larger frame size pumps, buildings, aircon, VSDs, cable and pipe lengths etc not just the prime cost of the pumps.
Spares for a smaller frame pump are cheaper than a larger frame pump.
Before posters jump on what I have said I repeat "may be". The calculations need to be done.
