Judge The Pump Hydraulic Design Through Numbers Before You Buy
A few well established hydraulic design parameters define the internal quality of an impeller design. Becoming familiar with those parameters and understanding their limits will enable pump buyers to make better pump buying decisions. Most of these design parameters are not reflected in the pump characteristic curve nor in the pump efficiency. These parameters allow buyers to compare the hydraulic design from different manufactures. Software is available to calculate and display these design parameters.
