In developing countries, the energy costs involved in water supply are generally the second highest item on municipal balance sheets.
This figure is even more significant if we remember that by 2020, 50 per cent of the populations of developing countries will have moved to the cities. So, clearly, the amount of energy used to supply drinking water and treat sewage is going to grow.
This makes it vital to ensure that water systems are as efficient as possible by minimising waste.
Life Cycle Cost
A system or pump's Life Cycle Cost (LCC) is the key factor engineers are working on to guarantee peak efficiency and also reduce the wastage of energy.
Life Cycle Cost consists of 3 basic factors: initial costs, energy costs and maintenance. It must be remembered that a pump or system's energy costs, together with installation, environmental, disposal and stoppage costs, account for 85 per cent of the total cost. Maintenance then amounts to an additional 5 per cent. It thus becomes clear that the initial cost only accounts for 10 per cent of LCC.
Therefore, giving a submersible pump a highly efficient motor and internal components can guarantee impressive energy savings, recouping the extra investment compared to the purchase of a pump with the same hydraulic characteristics but poorer energy efficiency within just two years*.
*Regular inspection of the system's components, operation and performance is essential for the achievement of efficiency targets.
USE ONLY WHAT YOU NEED: The UNIQA® solution
Precisely from these assumptions, the energy saving and the efficiency, Zenit has presented its new range of submersible pumps UNIQA ®, which combines the class IE3 motors with hydraulics of high efficiency and an innovative cooling system.
