Getting accurate cost of ownership data for pumps is challenging
As the total cost of ownership of pumping systems comes under greater focus,
THE TRUE COST OF PUMPS
Harvinder Bhabra looks at the typical method of calculating the cost and suggests other considerations that should be made to assess, and manage, an accurate figure
the highly engineered designs we now use. Tere are many types of pumps in use today, mainly classified between rotodynamic, positive displacement and other special designs. Over time, as industry processes became ever more sophisticated, the

umps have been used for the transfer of fluids for centuries, starting from the early Egyptian shadoof and Greek Archimedean screw through to
specifications for the various pump types demanded innovative pump manufacturing techniques and advanced features to keep pace. Some of these include hydraulic profiling, CAD/CAM, computational fluid dynamics, finite element analysis and 3D printing. Most recent developments come with the advent of the Internet of Tings (loT) and the collection of pump operating data and condition monitoring. lnstant
visibility of a pump’s performance provides a reduced risk of unplanned downtime caused by a failure. Tis article is based primarily on
rotodynamic centrifugal pumps, but some elements may also apply to other types of pumps.
Each sector or process has developed general industry– as well as process- or customer-specific specifications to suit its
