N Series Condensate pump

Condensate pump is an industrial device used in thermal power plants to transport condensate and other similar liquids. It belongs to the horizontal centrifugal pump category, featuring single-stage, two-stage, and inducer wheel configurations. The flow components are made of cast steel or stainless steel, and the driving method is electric motor.

N-type condensate pump has a flow rate range of 5-137 m³/h and a head range of 22-170 m. Models such as 100N130 and 150N110 can achieve water drainage via cooling water. It features a soft packing seal and a cantilever bracket bearing structure, with operating temperatures categorized into two scenarios: 120°C (for condensate water) and 80°C (for steam condensate). This pump is suitable for steam turbine generator units ranging from 750 to 3000 kW. During installation, it is essential to ensure independent pipeline support and maintain an alignment error of ≤0.1 mm between the pump shaft and motor shaft. Some power plants employ variable frequency speed regulation technology to adjust flow rates, thereby reducing energy consumption and improving operational efficiency.
