1. Featuring of variable speed control by inverter

Ebara-Booster-UN-FSAVariable speed drives are used since they can adjust the
motor’s power to fit specific needs, resulting in reduced
energy consumption and in increased savings.

2. Constant estimated terminal pressure control

The controller provides CETP (Constant estimated
Terminal Pressure) control that adjusts pump discharge
pressure in relation to pressure loss caused by pipe
resistance according to water flow. Thus, it can hold
down electric power consumption compared to constant
discharge pressure control with variable speed operation


3. Stable water supply

Pumps are in parallel operation for high demand and In
the event of pump/inverter fault, the controller
automatically activates another pump to assure water
supply without stopping system operation.


4. Compact layout

Ebara-Booster-UN2SLayout is very compact. All components are integrated on a
rugged steel base. It is ready for use by only connecting
with supply piping and to the power source. It occupies
lesser space and requires easier installation than
conventional units.

5. Extend the life of pump

Pumps are operation in automatic alternate parallel to
extend the life of the pumps.

6. Simple and compact inner control panel

Simple wiring by using RS485 digital communication can
reduce control panel dimension to be a compact design.

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.

less expensive low chrome cast iron with three to five times
the wear resistance of ordinary cast iron

Grundfos-DPK are Submersible pumps for dewatering and draining applications



Grundfos-DPK-ModularGrundfos DWK and DPK are submersible pumps designed for dewatering and drainage applications. The cast-iron construction and the hydraulic design contribute durability and high efficiency.

The differences between the DWK and DPK pump ranges lie in the discharge arrangement and the installation type.

The DWK is designed with a top discharge pipe and suction strainer, and is thus more suitable for temporary installation, whereas the DPK has a side discharge and a ring-stand or auto coupling (as accessories), and is suitable for permanent installations.





General description

To ensure reliable and optimum operation, Grundfos
drainage pumps, type DPK, are designed with two
types of impeller:
• 0.75 – 15 kW models have semi-open impeller
• 19 and 22 kW models have closed impeller.
DPK pumps are used for removal of surface and
underground water in small and medium systems



DWK/DPK are excellent pumps for dewatering and draining applications. The combination of compact design with high-pressure capability makes the pumps suitable for use in pits, whether for temporary or fixed installation. The installation design options provide the flexibility needed to cover many needs. Applications include:

  • Construction sites
  • Excavations
  • Tunnels
  • Fish ponds
  • Drainage pits.


Operating conditions

The DPK pump range is suitable for two operating
• continuous, submerged operation, S1, with min.
liquid level above the pump
• intermittent operation, S3, with the pump partly
See fig. 1

pH value
DPK pumps in permanent installations can cope with
pH values ranging from 4 to 10.

Liquid temperature
0 °C to +40 °C.


Density of pumped liquid
Maximum 1000 kg/m3.
In the case of higher densities, contact Grundfos.

Installation depth
Maximum 25 metres below liquid level.

Operating pattern
Maximum 30 starts per hour.




Features and benefits

  • Durability
  • High efficiency
  • Installation flexibility
  • High-pressure capabilities, cost-effectiveness.
