LIFE CYCLE COST
Life Style Costs
Average life cycle costs for industrial pumps.
Evaluating the Life-Cycle-Costs will identify the most financially attractive alternative.
The initial purchase price is a very small part of the life cycle cost for high usage pumps.
Minimizing energy consumption and plant downtime have a big influence on the total Life-Cycle-Costs.
Energy Costs
DÜCHTING PUMPEN offers a wide range of impeller sets for high efficiencies.
- high efficiency leads to low energy costs
Maintenance Costs
Robust design leads to long lifetime of the pump parts.
• low wear leads to low maintenance work and costs Easy accessible and changeable wear parts lead to short downtime for overhauls.
• short downtime leads to low maintenance costs
