High-Lift Pump for Building Water Supply & Mine Drainage

Our CDL Multistage Pump is a high-pressure, high-efficiency centrifugal pump
specifically engineered for medium and high-pressure fluid transportation
scenarios. Integrating advanced multistage impeller design, precision
manufacturing technology, and intelligent control systems, this pump is tailored
to meet the high-head fluid supply demands of industrial process systems,
municipal water supply, high-rise building water boosting, boiler feed water,
and reverse osmosis (RO) water treatment. With its compact modular structure and
optimized hydraulic circulation system, it can deliver stable and continuous
high-pressure fluid output, ensuring reliable operation even in long-term
continuous working conditions. Whether used for high-rise building secondary
water supply, industrial boiler feed water, RO system high-pressure water
supply, or municipal water pipeline pressure boosting, our CDL Multistage Pump
delivers exceptional performance, energy-saving efficiency, and long service
life, making it an ideal choice for medium and high-pressure fluid
transportation projects.

One of the core characteristics of our CDL Multistage Pump is its advanced
multistage impeller cascading design. The pump adopts a vertical multistage
centrifugal structure, with multiple precision-machined impellers cascaded in
series. Each impeller is optimized through computational fluid dynamics (CFD)
simulations, featuring a streamlined blade profile that maximizes energy
conversion efficiency. The cascading design enables the fluid to gain kinetic
energy step by step as it passes through each impeller, achieving high head
output (up to 400 meters) while maintaining stable flow. The impellers and pump
shafts are made of high-quality stainless steel (304 or 316L), which not only
ensures excellent corrosion resistance but also enhances the overall rigidity
and wear resistance of the rotating components. Additionally, the pump adopts a
modular design, allowing for flexible adjustment of the number of impeller
stages according to actual head requirements, greatly improving the adaptability
of the product to different project needs.

Excellent energy efficiency and stable high-pressure output are the key
advantages of our CDL Multistage Pump. The pump is equipped with an IE5
ultra-high efficiency motor that complies with the latest international energy
efficiency standards. The matching between the motor and the multistage
hydraulic system is precisely optimized, ensuring that the pump operates in the
high-efficiency zone under various working conditions. Compared with ordinary
multistage pumps, our product can reduce energy consumption by 15-25%,
significantly lowering long-term operational costs for users. The pump's
internal flow channel is designed with a smooth transition structure, minimizing
hydraulic losses and pressure fluctuations, thus ensuring stable high-pressure
output. Moreover, the vertical compact structure of the pump occupies a small
footprint (only 30-50% of that of horizontal multistage pumps), making it
suitable for installation in narrow spaces such as machine rooms of high-rise
buildings and industrial workshops with limited space.

Reliability and corrosion resistance are fundamental to the design of our CDL
Multistage Pump. The entire pump body, including the pump casing, impellers, and
suction/discharge pipes, is made of 304 or 316L stainless steel, which can
effectively resist corrosion from various media such as clean water, softened
water, and weak chemical solutions. The mechanical seal adopts a high-precision,
wear-resistant double mechanical seal structure, combined with an independent
lubrication chamber, which effectively prevents fluid leakage and ensures
long-term stable operation. The bearing assembly uses high-precision, low-noise
rolling bearings, which are lubricated with lifelong grease, eliminating the
need for regular lubrication maintenance. Furthermore, the pump is equipped with
multiple intelligent protection functions, such as overheating protection,
overload protection, dry-running protection, and voltage fluctuation protection.
These protection mechanisms can promptly detect abnormal operating conditions,
trigger alarms, and shut down the pump automatically, avoiding equipment damage
and ensuring the safety of the entire fluid supply system.

In terms of technical parameters, our CDL Multistage Pump offers a diverse
range of models to meet the specific requirements of different medium and
high-pressure fluid transportation projects. The flow rate ranges from 2 m³/h to
200 m³/h, and the head is adjustable from 10 meters to 400 meters, covering the
high-head transportation needs of various applications. The rated voltage is
available in 220V, 380V, 400V, 480V, etc., to match the power supply standards
of different regions and industries. The motor power ranges from 0.75 kW to 160
kW, and the frequency is 50 Hz or 60 Hz. The pump's operating temperature range
is -10℃ to 120℃, adapting to the temperature conditions of different transported
fluids. The pump's inlet and outlet diameters range from DN25 to DN150, and the
connection flange standards comply with GB, DIN, ANSI, and other international
standards, ensuring compatibility with different pipeline systems. Additionally,
the pump supports multiple control modes, including local manual control, remote
control, and automatic control (integratable with DCS or PLC systems),
facilitating centralized management and intelligent operation of the fluid
supply system.

Our CDL Multistage Pump boasts strong technical capabilities supported by
years of research and development in multistage centrifugal pump technology and
fluid dynamics. We have a professional R&D team consisting of hydraulic
engineers, electrical engineers, and structural designers, who are dedicated to
optimizing the pump's multistage hydraulic performance, energy efficiency, and
operational reliability. The pump undergoes rigorous testing before leaving the
factory, including hydraulic performance testing, energy efficiency testing,
durability testing, sealing performance testing, and electrical safety testing.
These tests ensure that the pump meets international quality standards (such as
ISO 9001, GB/T 5657) and can operate stably and efficiently in various complex
working conditions. Furthermore, we continuously adopt advanced manufacturing
technologies, such as CNC precision machining, automatic welding, and
intelligent assembly lines, to improve the precision and consistency of product
components, ensuring the reliability and service life of each pump.

The application scope of our CDL Multistage Pump is extensive, covering
industrial, municipal, commercial, and water treatment sectors. In the
industrial field, it is widely used for boiler feed water in thermal power
plants and industrial boilers, high-pressure process water supply in chemical
plants and pharmaceutical factories, and circulating water pressure boosting in
steel mills and electronics factories. In the municipal sector, it is applied

boosting, and water supply for urban public facilities (such as hospitals,
schools, and shopping malls). In the water treatment field, it is used for
high-pressure water supply in reverse osmosis (RO) systems, ultrafiltration (UF)
systems, and water purification plants, providing stable high-pressure fluid for
the water treatment process. In commercial and residential buildings, it is
