Purpose and characteristics
GN, N, and NB condensate pumps have better cavitation performance than general pumps. Mainly used for pumping condensate water from the condenser of the steam turbine generator unit in thermal power plants. It can also be used in other places where the medium is similar to condensed water.
Scope of use
The temperature of the transported liquid is below 80 ℃ (if a cooling chamber with a cooling structure is used, the temperature of the transported liquid can be below 150 ℃);
Head range: 32 meters to 150 meters;
Flow range: 5 cubic meters per hour to 120 cubic meters per hour.
