KQL Series Type Centrifugal IN-line Pump For Cooling Tower
● Utilizes a direct-drive structure, ensuring stable operation, reduced vibration and noise, and easy maintenance.
● The impeller and pump body are designed with an excellent hydraulic model, resulting in higher efficiency.
● Castings such as the pump body, pump cover, and impeller are manufactured using coated sand and precision casting processes, resulting in a smooth surface and excellent appearance and quality.
● Cast iron flow parts are fully covered with electrophoretic paint, significantly reducing the impact of corrosion on pump performance and lifespan.
