Lifecycle cost equation for pump systems

The life cycle cost of a pump system is the total cost of all system components over their lifetime. This is typically 10 to 20 years. The life cycle cost of a pumping system is calculated as: 

LCC = Cic + Cin + Ce + Co + Cm + Cs + Cenv + Cd


LCC  = life cycle cost 

Cic    = initial costs, purchase price 

Cin    = installation and commissioning costs 

Ce     = energy costs 

Co     = operating costs 

Cm    = maintenance and repair costs 

Cs     = downtime costs (loss of production) 

Cenv  = environmental costs 

Cd     = decommissioning/disposal costs 

The most significant life cycle costs are initial costs, energy costs, and maintenance and repair costs. As shown on the graph, energy costs are by far the greatest of all costs. 

Grundfos pumps and systems are cost-effective solutions when considered over the product or system lifetime. Use the Grundfos sizing tool to calculate lifecycle costs for pump systems.
