Kaiyuan QDL/F Vertical Multistage Pump is a high-performance, energy-efficient solution designed for various industrial and commercial applications. This pump features a compact structure, making it easy to install in limited spaces while ensuring stable operation and simple maintenance. Constructed from 304 stainless steel, it guarantees durability and corrosion resistance, offering a reliable alternative to older pressure-compensated pumps.
The pump is ideal for handling clean water, including cold or hot fluids without solid particles or fibers. It is not suitable for flammable or explosive liquids. The operating temperature range of the fluid is from -15°C to +120°C, with ambient working temperatures not exceeding +40°C.
This model is widely used in municipal water supply systems, industrial circulation, boiler feed, home water supply, environmental treatment, agricultural irrigation, and more. The stainless steel version is particularly suitable for brackish water, mineral water, distilled water, and swimming pool water, but the fluid temperature must be lower than that of the standard version.
Key specifications include a flow rate of 0.8–120 m³/h, head ranging from 5.6–330 meters, working pressure below 4.0 MPa, and motor power between 0.37–45 kW. The pump is certified under ISO9001, GSG, and TUV standards, manufactured in Shanghai, China, with HS Code 8413709990.
