Customer benefits
Applications
Alstom Power’s Condensate Extraction Pumps are specifically designed for the severe
operating conditions of conventional and nuclear power plants.
Alstom Power pumps are specially
designed and manufactured to
optimise the steam and water loop
on the turbine island using the very
latest Alstom turbine generator
technology.
The pumps are vertical multi-stage bowl
diffuser type, arranged inside a suction
barrel. The condensate water is drawn
from the condenser by the extraction
pumps and sent to the low pressure
feed heaters.
The pumps many benefits include:
In the nuclear power plants, three
pumps are generally installed - two
running and one in stand by. Variable
speed drives are possible and the
pump is made to operate safely and
economically at full speed under
partial load conditions.
Outstanding suction capacities
The design is centred around double
suction impellers, allowing very reduced
pump lengths but very high efficiency
Reliability
The Condensate Extraction Pumps have
been in operation at some sites for over
25 years with minimum servicing
Low maintenance costs
These very sturdy pumps only require
occasional servicing to check the thrust
bearing and shaft seal
