Carbon-filter system in waterwork, Rheinau der MVV Energie
AG
The situation
MVV Energie AG is an international distributor of energy and
services - a modern multi-utility group.
With a total turnover of 1.2 billion Euro and some 3,500 employees,
the group is one of the biggest regional distributors of energy
in Germany, and ranks among the most innovative enterprises
in the market.
In the Kafertal and Rheinau waterworks, MVV operates 85 water
extraction wells. The high iron content in the groundwater
combines with oxygen to produce massive ochre deposits on
the inside of the cast iron pumps.
"For
pumps in the shallow boreholes, the ochre builds up quickly
and the pump only performs [at] 50%," says Werner
Faschingbauer of MVV.
The Grundfos solution
Now, more than 30% of the company's wells are equipped with
Grundfos high-grade steel SP pumps (in new installations this
share is nearly 50%.).
Herr Faschingbauer also uses the new Grundfos infrared
control unit. He can change factory settings and monitor
the installation of a pump by remotely calling up actual
operating data (e.g. current consumption, supply voltage,
operating hours).
The outcome
- Quality materials. "In our
opinion the deposits on the smooth high-grade steel
surfaces of an SP pump stick less firmly than on the
rather coarse cast iron. It's also easier for us to
remove the ochre scale."
- User-friendly. "You don't
need to have any specialist knowledge. All units are of
the same design - once you have dismantled and reassembled
one of these pumps, you know what's what."
- High efficiency. "In this
field Grundfos now has a leading edge."
- Reduced Cost of Ownership. "Now
we use the diagnosing unit to test the units
that fail to run."
The SP pumps and CU3 are integral parts of a cost-effective
and reliable water supply.
