Product Applications:
Pipeline transport systems for waterworks, circulating water systems in power plants and industrial facilities, irrigation and drainage pumping stations, building water supply systems, heating systems, and cooling systems.
Specifications:
Size: DN150–DN1400 mm; flanges comply with the GB/T17241.6 standard (customization available).
Rotational Speed: 740, 990, 1480, and 2960 r/min (speed varies by model).
Flow Rate: 65–13,600 m³/h.
Head: 9–320 m.
Notes: 1. Regarding Net Positive Suction Head (NPSH), factors such as local altitude (atmospheric pressure) and medium temperature (saturated vapor pressure) must be considered.
2. When selecting motor power, the impact of local altitude must be taken into account (especially at altitudes exceeding 1,000 meters).
Product Overview:
The KQSN-X series single-stage double-suction centrifugal pump is an upgraded product that integrates Kaiquan's advanced hydraulic model research while enhancing structural reliability, versatility, and configuration optimization.
This series utilizes superior hydraulic models and features an optimized overall structure to improve operational reliability and performance. The rotor offers high rigidity and low moment of inertia, resulting in low starting current and minimal impact on the power grid. The optimized external dimensions reduce foundation loads and save installation space. The bearing assembly is designed for easy disassembly and on-site maintenance, preventing bearing damage caused by excessive heat that could otherwise lead to unstable pump operation. Performance parameters for this series are planned based on years of market demand data; through the matching of various casing and impeller models, the pumps are better suited to diverse site requirements, ensuring high efficiency and reliable operation.
