The motor nameplate rating shall be at least 110% of the pump rated power.
2) The pump shall have a continuous head rise from the rated point to the shut-off point with the head rise not less than 10% of the rated head.
3) The capacity at the end of the curve shall not be less than 120% of the rated capacity
4) The minimum continuous stable capacity shall not exceed 50% of the rated capacity.
5) The preferred working area of the pump should be 70% to 120% of the best efficiency flow of the provided pump.
