Product Overview:

The GDL vertical multistage centrifugal pump is a modern and advanced solution designed for high efficiency, compact structure, and easy installation. It features a casing made from high-grade stainless steel (1Cr18Ni9Ti) and a mechanical seal that offers excellent wear resistance, zero leakage, and long service life. The hydraulic balance system effectively manages axial forces, ensuring stable operation and low noise levels. Compared to traditional DL pumps, the GDL model can be easily installed in the middle of a horizontal pipeline, making it more convenient for various applications. It is ideal for water supply and drainage in high-rise buildings, deep wells, mines, and fire protection systems. This pump is suitable for transporting cold or hot water, general media, or other liquids with physical and chemical properties similar to water across major industries. Type Designation:
