The pump is rated pressurepump work for the highest allowable pressure, but their work is determined by external pressure load, pump life are directly related to their work pressure.
Petrochemical equipment is often 24-hour continuous operation, when the work pressurepump should be made much lower than the rated pressure, and speed work should also be lower than the rated speed.
