MEI - Minimum efficiency Index - It has to do with the efficiency of the impeller to deliver water at certain heightsOriginally Posted by Josh van Niekerk
np% - the n has a long side to the n and stands for efficiency - It would indicate the motor power efficiency in % and is often rated at different loads
The above is my understanding from an electrical side and I am no expert in the mechanical side of pumps
