PDL Vertical multi-stage centrifugal pump

Feature：

• This CDL pump adopts a vertical mounting structure with the inlet and the outlet both arranged horizontally. It can be designed with additional stages to meet different head requirements. Designed with a compact structure, low noise, and space-saving installation, it is ideal for environments with limited space such as high-rise buildings. The pump and motor are equipped with a single-face seal, while the fixed flange uses an O-ring for radial sealing. The pump is suitable for conveying thin, clean, non-flammable, non-explosive liquids free of solid particles or fibers.
