KQSN-X Double Suction Pump

Caliber: DN150-DN1400mm, flanges comply with GB/T17241.6 standard (customization available for special requirements).
Rotational speed: 740, 990, 1480 and 2960 r/min (corresponding to different models).
Capcity: 65-13,600 m³/h.
Head: 9-320 m.
Notes: 1. Regarding the net positive suction head available (NPSH) of the equipment, the influence of local altitude (atmospheric pressure) and medium temperature (saturated vapor pressure) should be taken into account.
2. The selection of the motor power to be used should take into account the influence of the local altitude (especially when it is over 1000 meters).

The KQSN-X single-stage double-suction centrifugal pump is an upgraded product that integrates the advanced hydraulic model research results of Kaiquan, upgrades the structural reliability, and optimizes the universality and configuration.
This series of products comprehensively adopts excellent hydraulic models and, by optimizing the overall structure, enhances operational reliability and overall performance. The rotor has good rigidity and a small moment of inertia, resulting in a low starting current and minimal impact on the power grid. The dimensions have been optimized, reducing the base load and saving installation space. The bearing components have a convenient disassembly and assembly structure for on-site maintenance, avoiding bearing damage caused by excessive heating and ensuring stable pump operation. This series of products are designed based on the parameters of market demand over the years. Through the matching of various casings and impeller models, it is more suitable for various on-site parameter requirements and ensures efficient and reliable operation.
According to the user's requirements, different choices can be made. It is suitable for steam-water heat exchange, water-water heat exchange and other working conditions. It is a heat exchange equipment for centralized heating in thermal power plants, regional heating in boiler areas and industrial production. It can be widely applied in heating and hot water supply for residential areas, office buildings, commercial buildings, hotels and enterprises and institutions, as well as winter heating in air conditioning systems, domestic hot water supply and industrial closed-loop water cooling and other special working conditions.
