KSB - HGM-RO High-pressure pumps for reverse osmosis systems



KSB-HGM-RO high-pressure pump – reliable drinking water treatment in reverse osmosis systems



Drinking water production in RO systems requires a high-pressure pump of top reliability which provides continuously economical operation. KSB responds to this need with an ideal solution: the HGM-RO high-pressure pump.







High-pressure pumps  HGM-RO High-pressure pumps for reverse osmosis systems need to be able to handle the harsh conditions which prevail in seawater desalination plants.



KSB has opted for radially split high-pressure pumps.

Their radially split design makes HGM-RO high-pressure pumps particularly robust, enabling them to cope with the extreme conditions of drinking water treatment in seawater desalination.




Benefits of using KSB’s radially split high-pressure pumps in reverse osmosis systems:

HGM-RO-Radially-split-designMinimum energy input, low operating costs

Excellent NPSH value thanks to axial inflow with suction stage impeller. Continuously high efficiencies.


Compact design

Internal, product-lubricated plain bearings with a short bearing span ensure smooth running and therefore high pump availability and reliability as well as a long service life of wear parts.


Corrosion-resistant design

The HGM-RO high-pressure pump is made of duplex or super duplex stainless steels. Its corrosion-resistant design (e.g. dry shaft) translates into a long service life.


Low monitoring requirements

There is no need for an additional lubrication system, and the pump does not require any vibration or bearing temperature monitoring. This saves both initial and operating costs for the pump set.

Minimum maintenance costs

Because of its axial inlet, the HGM-RO high-pressure pump has just one mechanical seal, which minimises spare parts costs. The ring section design ensures top reliability in the extreme conditions of reverse osmosis systems. No lubrication systems are required. The mechanical seal is easy to replace.

Reduced construction costs

The pump’s compact design, low weight and smooth running lower the requirements to be met by the foundation. Flexible connection branches facilitate connection to the system piping.


Easier to install and dismantle than axially split pumps

The pump can be dismantled and reassembled from either side. The wear parts are easily accessible.
