HGM-RO. Multitec-RO.Trusted Power in Seawater Desalination.

Introduction2

Quality that performs.

Drinking water is vitally precious. In

many parts of the world, the only way

to provide sufficient affordable supplies

is by extracting it from salt water.

For decades, KSB has led the way

in innovative and efficient seawater

desalination by reverse osmosis.

Our high-pressure ring-section pumps

meet the demands of non-stop operation

in plants of all sizes.

KSB provides solutions for the entire

desalination process – from seawater feed

right through treatment and on to piping

the extracted water.

Applications4

We’ve done it before, and we keep on innovating.

Innovative technology from KSB has generated decades of efficient

solutions in RO. And as you’d expect, we’re on call for customers

with comprehensive service and a broad range of products in

this area, too.

n  All-in pressure boosting and energy recovery systems:

- High-pressure pump, pressure exchanger, booster pump

- High-pressure pump, motor, turbine

n  Engineering package combines pump and intake

structure optimisation

n  On-site service

n  Test field, engineering and model testing to customer specs

at our headquarters in Frankenthal

n  All pumps and valves required for the desalination

process, such as:

- Pumps for pre-treatment, post-treatment and purification

processes

- Pumps for water transport

- Valves for all shut-off and control duties

The hydraulic SalTec® N System increases pressure and recovers energy. It efficiently rounds off the KSB range of components for RO desalination. And significantly reduces the cost of water.

Components that match each other perfectly: n  KSB’s HGM-RO/Multitec-RO high-pressure pumpsn  KSB’s SalTec® N pressure exchangern  KSB’s RPH-RO booster pump

Membranes are not included in the scope of supply.

Good value, effective, unique: SalTec® N System – desalination that makes special sense.

The individual solution to the toughest demands: HGM-RO.

Our high-pressure HGM-RO pump is top of the range – and on

top of even the toughest conditions.

We developed the HGM-RO specifically for reverse osmosis.

This pump stands up to all the demands which that process

puts on it.

As seawater is such a difficult medium, we planned its con-

struction with duplex and super duplex steel. And we gave

the HGM-RO a compact design that perfectly masters huge

osmotic pressures. Starting the pump puts minimum demands

on membrane and material.

Top HGM-RO quality enables round-the-clock production of

more than 30,000 m3/day per desalination train. Continuous

optimisation ensures the best possible efficiency and low energy

consumption. Very smooth operation, increased service lives and

easy maintenance are further hallmarks of this premium pump.

HGM-RO meets the highest demands – and is top choice for

seawater desalination.

Design:

Horizontal, radially split, medium-lubricated ring-section pump

with radial impellers and plain bearings, axial or, on option, radial

single-entry inlet, duplex steel design.

The standard solution for small and medium sized plants: Multitec-RO.

Practice, they say, makes perfect. KSB has years of experience

in small- or medium-scale RO plants as well. And provides an

economic standardised solution for their special needs.

Multitec-RO is ideal for stationary or floating installations in

hotels, large ships, transportable containers and medium-sized

plants. Optimum efficiency keeps energy costs down. And with

a wear-resistant plain bearing and just one discharge-side

shaft seal, easy servicing is guaranteed as well.

Multitec-RO pumps are economical, reliable and corrosion-

resistant – the individual standard for demanding customers.

And they’re usually available immediately!

Design:

Horizontal, multistage ring-section pump. Axial suction nozzle.

Discharge nozzle can be turned in steps of 90 °. Closed radial

impellers. Duplex or super duplex design also for chilled water

applications.

First-class results demand first-class materials.

What really matters in high-pressure pumps? As designers, makers

and suppliers, we know it’s the quality of the materials. We have

over 30 years’ experience in this area, and invest more than

¤ 20 million annually in Research & Development. Which is why

we lead the way in innovative duplex design.
