Product Overview of the CDL/CDLF Vertical Multistage Stainless Steel Stamped Pump

The CDL/CDLF vertical multistage stainless steel stamped pump is a next‑generation, multifunctional product designed and manufactured by our company based on superior overseas pump models and tailored to meet users’ operational requirements. It can handle a wide range of media, from tap water to industrial liquids, and is suitable for various temperature, flow rate, and pressure conditions.

The product’s main body is fabricated by stamping and welding stainless steel sheets. Compared with the sand‑casting pumps commonly used in China today, it offers advantages such as a compact footprint, light weight, high efficiency, low noise, minimal vibration, easy installation, and an aesthetically pleasing appearance. Its bearings and shaft seals are made of highly wear‑resistant hard alloy, ensuring long service life and reduced maintenance requirements. It is a new energy‑saving, environmentally friendly product that is strongly promoted by the national government.
