Total Purchase Cost

The total purchase cost of an ESP system is the sum of the costs of the ESP, options, auxiliary equipment, instruments and controls, taxes, and freight. The last three items generally are taken as percentages of the estimated total cost of the first three items. Typical values are 10% for instruments and controls, 3% for taxes, and 5% for freight.
 

Costs of standard and other options can vary from 0% to more than 150% of ESP base cost, depending on site and application requirements. Other factors that can increase ESP  costs are given in Table
