Wire-to-Water Efficiency

The efficiency of a pump is a ratio of the energy delivered by the pump to the energy supplied to the pump shaft. It is best represented by the wire-to-water efficiency, which combines the overall efficiency of the pump and the motor. Wire-to-water efficiency is a measure of the efficiency of the complete facility considering external piping losses, external elevation head and all internal pump losses. This efficiency is an index of the effectiveness of the entire system in delivering fluid from its pumping level to its final delivery point and is the efficiency most easily determined in the field.

Coatings Improve Efficiency

Polymer coatings are specifically designed for improving the efficiency of fluid handling equipment and to protect pumps from the effects of erosion/corrosion. The self-leveling and hydraulic smoothness makes these coatings ideal candidates for lining hydraulic passages of pumps and associated equipment.

Take Action

You have changed the light bulbs, purchased high efficiency motors, improved your chiller performance, reconditioned the cooling towers, upgraded your boilers and installed the latest building materials to reduce energy cost. Pumps repaired and coated with polymer coatings have had performance gains range from 7% on new pumps to 40% on pumps repaired and coated with polymer coatings.

What has your experience been with the use of polymer coatings for repairs and to improve efficiency?
