**Application:**
The N-type condensate pump is designed with a lower NPSHr compared to standard water pumps, making it ideal for power plant condensate systems. It can also be used in other applications where suction conditions are prone to cavitation. The pump is suitable for handling liquids at temperatures below 80°C. Additionally, it is commonly used in coal-fired power plants for transferring water and low-pressure heater media at temperatures under 105°C.
**Data Range:**
- **Capacity:** Q = 8–720 m³/h
- **Head:** H = 37.7–186 m
**Pump Structure:**
The N-type pump is a cantilevered, single or two-stage horizontal centrifugal pump. The suction inlet is axial, while the discharge is vertical. To achieve a low NPSHr, certain models like 6N6, 200N65, 200N150, and 200N135 include an idler. The rotor is supported by rolling bearings with thin oil lubrication. From the motor side, the pump rotates counterclockwise. The 8NL-12 model is a vertical, middle-split, idler, single-stage condensate pump, while the 14NL-14 model is a vertical, middle-split, idler, two-stage condensate pump.
**Material:**
- **Casing:** Cast iron or carbon steel
- **Impeller:** Stainless steel
- **Idler:** Stainless steel
