By applying some ‘out of the box’ thinking to capital investment, is the cheapest pump really the cheapest pump? Industry norms and pre-conceptions tend to lean heavily to centrifugal pumping systems. However, by looking deeper, in this case focusing on electrical consumption, a dramatic saving is clear. Expanding research based on The Hydraulic Institute paper Pump Life Cycle Costs: A Guide to LCC Analysis For Pumping Systems increases potential.
This paper lists all costs associated with a pump’s life. These are:
* Initial investment costs (Cic)
* Installation and commissioning (start-up) costs (Cin)
* Energy costs (Ce)
* Maintenance and repair costs (Cm)
* Downtime and loss of production costs (Cs)
* Environmental costs, including disposal of parts and contamination from pumped liquid (Cenv)
* Decommissioning/disposal costs, including restoration of the local environment (Cd)
Based on the calculation above, there a representative saving for the selected utility alone of approximately 25% per year.
