The Agricultural Engineering Department has tested more than 500 pumping plants in the past 25 years. The average performance indicates that about 30 percent of the energy used for irrigation could be saved if all pumping plants operated at the Nebraska Performance Criteria.
There were many causes for poor pumping plant performance. Major causes were poor power unit performance, and poor pump performance often caused by improper pump adjustment.
This circular discusses proper pump adjustment to attain maximum efficiency.
