In developing countries, the energy costs involved in water supply are generallythe second highest item on municipal balance sheets.This figure is even more significant if we remember t hat by 2020, 50 per cent ofthe populations of developing countries will have moved to the ci ties.

Aboutof world energyconsumption is usedfor pumping and treating

urban and industrialwastewater.

Most of the worldswater systems energyconsumption could be

reduced by 25% throughinexpensive measuresto achieve peak efficiency.

So, clearly, the amount of energy used to supply drinking water and treat sewageis going to grow.This makes it vital to ensure that water systems are as efficient as possible byminimising waste.

Life Cycle Cost consists of 3 basic factors: initial costs, energy costs andmaintenance.It must be remembered that a pump or systems energy costs, togetherwith installation, environmental, disposal and stoppage costs, account for85 per cent of the total cost. Maintenance then amounts to an additional5 per cent. It thus becomes clear that the initial cost only accounts for 10per cent of LCC.

*Regular inspection of the systems components, operation and performance is essential for the achievementof efficiency targets.

A system or pumps Life CycleCost (LCC)is the key factorengineers are working on

to guarantee peak efficiencyand also reduce the wastageof energy.

Therefore, giving a submersible pump a highly efficient motor and internalcomponents can guarantee impressive energy savings, recouping the extrainvestment compared to the purchase of a pump with the same hydrauliccharacteristics but poorer energy efficiency within just two years*.

Just as only 10 per centof an icebergs total bulkis visible while most of itis concealed underwater,only the initial cost ofa system can be seen,since the operating andmaintenance costs,the lions share and muchhigher than the purchasing

costs, are not immediatelyobvious.

High-efficiency PREMIUM IE3motors function, in according

with NEMA A standard, andisulation in class H. GuaranteedS1 duty cycle in fluids at atemperature of 60 C or higher.

CHOOSE AN ELECTRIC PUMP THAT HELPS TO IMPROVEYOUR FUTURE WITH INNOVATIVE SOLUTIONS, UNIQUEIN THE INDUSTRY.

Look to the future by implementing measures that really help to reduce energy

wastage and make better use of energy resources, approaches any modernorganisation should adopt.

A motor in efficiency class PREMIUM IE3, high efficiency hydraulics and a patented

cooling system. These are the keys to the success of the UNIQA series.

This high-performance product delivers minimal maintenance costs, reduces

the risk of system stoppages, and provides constant, durable total efficiency

in pump operation.

CHOOSE UNIQA, THIS IS WHAT YOU NEED.Oversized heavy-dutybearings designed for 50,000hours of operation.

All hydraulic components aredesigned to provide highestefficiency and best performance.

The motor is cooled downby a patented closed-circuit internal

re-circulation system. This way, shouldany soiled liquid penetrate the oilchamber due to possible wear of the firstmechanical seal, the glycol usedin the process wouldnt be affected.

turn over a new leaf: choose quality, research, innovation and sustainability

CHOOSING UNIQAMEANS HIGH EFFICIENCYNOT ONLY IN PERFORMANCE,BUT ALSO IN OPERATING COSTS.For a real understanding of how efficient UNIQA is, lets take a look at the figures

for a small lifting plant. Lets suppose we have calculated a duty point with a flow

rate of 30 l/sec, lifted to a height of 13.5 m.

We now know we need a hydraulic power of 3.973 kW (Pidr

=gQ H),for a total of 10 working hours a day (3,650 a year),with an energy cost

per kWh of 0.10 /kWh.

This will be the starting point for our calculations.

THE VALUE OF UNIQA

Lets compare the performance at the duty point indicated above of a UNIQA

submersible pump with efficiency class Premium IE3 and high efficiency hydraulics

with that of an electric pump with standard motor and conventional hydraulics.

UNIQAis so efficientthat up to 30% of energycosts can be saved

PER CENT

PER CENT PER CENT

The example highlights the fact that using a UNIQA pump with efficiency class PREMIUMIE3 (+6.2%) motor and high performance hydraulics (+33%) compared to a STANDARDpump, yields improved global system efficiency, at the duty point in question, of 6%, thusproviding considerable cost savings.
