Customer benefits
Alstom Power’s Concrete
Volute Pumps offer exceptional
efficiency, often in excess of 90%
maintained over the machine life.
Our Concrete Volute Pumps are
already installed in many of the
world’s most modern nuclear
power plants, including the 59
plants in the French fleet.
They offer a number of
advantages over conventional
solutions using all metal pumps:
• nmatched reliability with
U
over 30 years proven operation
in thermal or nuclear power
stations, with an average
reliability in excess of 99.9%
Technical specifications
• The suction duct (different shapes
t may be adopted)
• he volute, shaped and designed
T
for hydraulic efficiency and easy
installation
• The mechanical parts embedded in
t the concrete
• emovable parts (wear rings,
R
impeller, shaft, bearings, thrust
bearing, shaft seal)
• nit flow rate can be as high
U
as 40 m3/s – that offers the
possibility of installing fewer
pumps for the same service,
increasing reliability of the
pumping plant

several applications, Alstom has
references in power projects (both
fossil and nuclear), drainage and
irrigation as well as marine works
for ports and harbours.
