Overhung-type pumps for clean water
Rated-flow water supply pumps
Etanorm 
KSB manufactures overhung-type pumps Etanorm for water supply,
about 100 000 pieces per year. In addition to a classical overhung-type pump, the so-called block-type pump Etabloc is manufactured.
As materials, gray cast iron, malleable cast iron, bronze, and acid-resistant steel are used.
Capacity (Q) | max. 660 m³/h |
Head (H) | max. 102 m |
Temperature | max. 140ºC |
Pressure rating | PN 16 |
For larger flows, KSB has Etanorm-R of Omega and RDL-series.
Etanorm-R is the so- called ’’bigger brother’’ of Etanorm-series.
All models are provided with a double volute chamber, the efficiency and NPSH are as possible brought to perfection.
Capacity (Q) | max. 2300 m³/h |
Head (H) | max. 90 m |
Temperature | max. 140ºC |
Pressure rating | PN 16 |
As materials, gray cast iron, malleable cast iron, bronze, and acid-resistant steel are used.
For larger flows, KSB has pumps with a double volute chamber of Omega and RDL-series.
Pumps manufactured from moulded stainless steel
Etachrom
In addition to cast pumps, rated-flow water supply pumps are manufactured from
moulded acid-resistant steel - Etachrom.
In addition to water supply, owing to the material Etachrom pumps can be used
for pumping neutral chemicals as well.
Capacity (Q) | max. 110 m³/h |
Head (H) | max. 104 m |
Temperature | max. 110ºC |
Pressure rating | PN 12 |
Pumps with a double volute chamber. Omega, RDLO, RDL, RDLP
RDLO
Pumps of Omega and RDL series are pumps with a double volute chamber.
They are suitable for places where it is necessary to pump particularly large flows
and a higher reliability of operation and low NPSH values are required.
Capacity (Q) | max. 23 000 m³/h |
Head (H) | max. 700 m |
Temperature | max. 175ºC |
Pressure rating | PN 25-100 |
As materials, gray cast iron, malleable cast iron, bronze, and acid-resistant steel are used.
Propeller pumps
They are mainly suitable for places where it is necessary to pump large flows at a low head.
Main places of use are single-stage pumping units, cooling water pumps of power plants and polder pumps for larger settlements.
Wastewater pumps with special hydraulics are also manufactured, see wastewater pumps, Amacan K.
Amacan P
This is a submersible pump with an axial-flow impeller to be installed in the pipe.
Capacity (Q) | max 7000 l/s |
Head (H) | max. 12 m |
Temperature | max. 40ºC |
Amacan S
This is a submersible pump with a semiaxial-flow impeller to be installed in the pipe.
Capacity (Q) | max. 6000 l/s |
Head (H) | max. 55 m |
Temperature | max. 60ºC |
SEZ, SNW
It is a submersible pump with a dry motor, an axial-flow impeller or a mixed-flow impeller.
Capacity (Q) | max. 18 000 l/s (100 000 l/s)* |
Head (H) | max. 80 m |
Temperature | max. 80ºC |
* Pumps of this type, manufactured by KSB, with the highest capacity in the world have been supplied to Zaohe Pumping Station at the Jiangtsu River, in China. Each pump pumps 100 m³/s at the head of 7 m, the revolutions velocity is 175 r/min, the impeller diameter is 6 m and the motor power is 7000 kW.
Pumps PHB, PBY, SEB, SPB with a concrete body
These are high-capacity pumps with a concrete body, with an axial-flow impeller or a mixed-flow impeller.
Capacity (Q) | max 100 000 m³/h (standard sizes) |
Head (H) | max 25 m |
