Sulzer Pumps’ aim of becoming the domi-

nant supplier of pumping solutions for

concentrated solar power (CSP) is report-

edly being realised with the awarding of

multiple contracts across the globe.

Utilising its considerable global exper-

tise, the company continues to design and

manufacture pumping solutions for the

complex processes 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 construc-

tion. The advantages of the pumps being

supplied by a local South African com-

Effective slurry blasting becomes easier

Engineered using quality components, the

Slurry Blaster offers mining and plant oper-

ations a cost effective cleaning tool for all

applications where slurry has become an

issue and needs to be washed away.

Lee Vine, MD of Integrated Pump Rental,

says the company has fast established a

reputation for identifying areas in process

plants where an effective alternative solu-

tion is needed to cope with the day-to-day

activities. “It is sometimes in the most obvi-

ous places that there is a need for more

reliable equipment that is capable of with-

standing the rigours of daily use,”Vine says.

The Slurry Blaster is a hydro mining

equipment solution which is said to offer

optimum performance coupled with reli-

ability. Typical applications include plant

floors and sumps, drainage areas, tailings

dams, process water dams and other diffi-

cult to reach areas.

“Not all applications are the same and

for this reason, we have made the Slurry

Blaster available in three main con-

figurations but it can be modified

to suit individual customer applica-

tions, should this be necessary,”

Vine says.

The Slurry Blaster can be

provided on a pontoon for

use on ponds and dams, it can

be trailer mounted or it can be a tradi-

tional manual set up.

“The decision as to which configuration

to use is based on the application at hand

and our technical team has the necessary

competency to assess the situation and

propose the appropriate option to the cus-

tomer,”Vine says.

Each installation of the Slurry Blaster

comes standard with a 37 kW feed pump

with float, a 22 kW slurry pump for the

removal of the slurry, a 200 m heavy duty

layflat hose and an electric control panel.

The Slurry Blaster units are available for

medium or long term rental, outright pur-

chase and on a full turnkey project basis.

pany are numerous and

will give the local opera-

tion’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 contri-

bution 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 includes 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 exchanger which converts

water to steam and effectively makes up

the conventional steam cycle.

HTF pumps specifically are manufac-

tured for high temperature applications

that include thermal transients and sealing

of flammable and hazardous fluids under

extreme cyclic operating conditions. With

Sulzer provides pumping solutions for solar plants

A growing number of solar plants are making use of Sulzer Pumps’

engineered solutions.

experience in HTF pumps dating back

to 1985, Sulzer Pumps has an in-depth

understanding of the requirements and

operating philosophies involved to pro-

duce pumps that can perform under such

strenuous conditions.

HTF and solar heat transfer pumps will

be based on the company’s newHZB range

which is able to pump liquids at tempera-

tures in excess of 400 deg C, pressures of

more than 50 bar and flows in the region of

4 000 m³/h. In order to provide fully engi-

neered pumping solutions covering entire

solar power plants, the company is also

supplying feed water pumps, HTF overflow

pumps and water 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 countries and

regions such as Spain, India, Israel, the

Middle East and the USA – a growing

number of plants is 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.
