ulzer Pumps’ aim of becoming the dominant supplier of
pumping solutions for concentrated solar power (CSP) is be-
ing realised with the awarding of multiple contracts across
the globe.
Utilising its considerable global expertise, the company continues
to design and manufacture pumping solutions for the complex pro-
cesses within these plants wherever the requirement for precision
manufacturing is of a primary concern.
Similarly, Sulzer Pumps South Africa has been awarded contracts to
supply full solutions for local solar power plants that are currently
planned or under construction. The advantages of the pumps being
supplied by a local South African company are numerous and will
give the local operation’s design teams the ability to showcase their
abilities within the global arena.
“Sulzer Pumps is a company with a global footprint and its branches
from Spain, Germany and India will make a contribution to bringing
these projects to a successful conclusion,” says project manager
Henno Raaths. “Sulzer Pumps South Africa will however take the full
lead in terms of engineering and supply of the highly sophisticated
equipment.”
The recent rise in local renewable energy projects include advanced
solar power plants using CSP technology. CSP operations require
a special heat transfer fluid (HTF) or molten salts to be circulated
around a solar heat absorber and pumped to a special heat ex-
changer which converts water to steam and effectively makes up
the conventional steam cycle.
HTF pumps specifically, are manufactured for high temperature ap-
plications that include thermal transients and sealing of flammable
and hazardous fluids under extreme cyclic operating conditions.
With experience in HTF pumps dating back to 1985, Sulzer Pumps
has a vast understanding of the requirements and operating philos-
ophies involved to produce pumps that can perform under such
strenuous conditions.
HTF and solar heat transfer pumps will be based on the compa-
ny’s new HZB range which is able to pump liquids at temperatures
in excess of 400oC, pressures of more than 50bar and flows in
the region of 4000m³/hour. In order to provide fully engineered
pumping solutions covering entire solar power plants the company
is also supplying feed water pumps, HTF overflow pumps and wa-
ter condensate extraction pumps complete with sealing systems,
drives, motors and instrumentation. Sulzer South Africa further has
the expertise to assist with installation, commissioning and service
support across the complete range of pumps.
Across the globe in places like Spain, India, Israel, Middle East and
the USA a growing number of plants are making use of Sulzer Pumps’
engineered solutions. Currently the fleet of CSP pumps within these
areas includes nearly 250 HTF pumps, 100 feed water pumps, 40
condensate extraction pumps, as well as numerous cooling water
pumps and hot water circulation pumps. “With such a large and ac-
tive CSP pump population, it is easy to see why we have become the
trusted name in the supply of specialist engineered pumping solu-
tions for renewable energy projects,” concludes Henno.
