Overview:
N and NL type condensate pumps are used in thermal power plants to convey condensate water and other liquids similar to condensate water. This series of pumps features exceptionally excellent suction performance.
Performance range:
Flow rate Q = 8–720 m³/h
Head H = 38–183 m
Temperature T: <80℃
(Special requirements can reach 120℃)
Structural features:
The N-type condensate pump comes in three configurations: horizontal cantilever single-stage, horizontal cantilever single-stage with an inducer, and horizontal cantilever two-stage. The NL-type condensate pump is available in two vertical mid-opening single-stage designs with an inducer and two vertical mid-opening two-stage designs with an inducer.
The horizontal condensate pump features an axial, horizontal suction inlet and a vertical discharge outlet. The vertical condensate pump has a horizontal suction inlet and a horizontal discharge outlet. Depending on user requirements, the shaft end seal can be either a packing seal or a mechanical seal.
The horizontal condensate pump is connected to the motor via a claw-type flexible coupling, while the vertical condensate pump uses a pin-type flexible coupling. From the perspective of the transmission direction, the pump rotates counterclockwise.
