Life cycle cost of a pumping system
Cost of the pump ownership
Life-cycle cost (LCC) analysis takes into account all pumps related costs from purchasing and until utilization.
LCC analysis is a convenient and transparent method for evaluation of different methods of pump system optimisation.
LCC = Cic + Cin + Ce + Co + Cm + Cs + Cenv + Cd
Cic = initial cost or purchase price (e.g., of the pump, system, pipe, valves, control system, auxiliary equipment)
Cin = installation and commissioning including, training courses for staff.
Ce = energy costs (predicted cost for system operation, including pump driver, controls, and any auxillary services)
Co = operation costs (labor cost of normal system supervision).
Cm = maintenance and repair costs (routine and predicted repairs)
Cs = down time costs (loss of production)
Cenv = environmental costs (contamination from pumped liquid and auxiliary equipment)
Cd = decommissioning/disposal costs (including restoration of the local environment and disposal of auxiliary services).
The typical structure of a centrifugal pump.
The pump system is completely dominated by the energy cost.
Energy and maintenance have the biggest part of LCC structure.
Energy cost is the much bigger than the initial cost of pump's LCC.
That is why efficiency and reliability play the most important role.
But customers usually select the cheapest pump despite the fact that in the future he will pay much more for electricity and service.
Very often it happens because different people and companies are responsible for acquisition and for an operation of pumps.
They persecute different goals.
