Improving Pump Performance, Charles M. Burt, Frankline Gaudi, Daniel J. Howes

BioResource and Agricultural Engineering

Options can be specified to minimize power consumption by vertical pumps – both when new and over the life of the pump. Options discussed include bowl coatings, proper well development, improved suction screens, using closed impeller designs, increasing column size, using new bearings, providing proper bearing lubrication, impeller balancing, and polishing impellers. The proper TDH and flow rate must be specified, and the advantages of VFD controls are covered.

Agricultural Water Conservation And Efficiency In California - A Commentary, Charles M. Burt, Peter Canessa, Lawrence J. Schwankl, David F. Zoldoske

BioResource and Agricultural Engineering

This is a Commentary on some of the key points that are presented in “More with Less: Agricultural Water Conservation and Efficiency in California” by Cooley, ChristianSmith, and Gleick of the Pacific Institute, September 2008 (referred to as the “PacInst Paper” in the remainder of this discussion).

The authors of this Commentary have over 120 years combined of experience in agricultural and landscape irrigation. They have worked world-wide in design and installation of all types of irrigation systems (including automated drip systems from 1975 on), design and implementation of irrigation scheduling programs since 1977; design and implementation of water conservation …

Estimating The Savings From Improving Pumping Plant Performance., Derrel L. Martin

Department of Biological Systems Engineering: Conference Presentations and White Papers

This brochure describes a method to estimate the cost of pumping water and to compare the amount of energy used to that for a well maintained and designed pumping plant. The results can help determine the feasibility of repairing the pumping plant.
