CDL/CDLF Vertical Multistage Pumps are manufactured using advanced technology. Their key advantages include an optimized hydraulic design for high efficiency and energy savings. The internal impellers, pump casings, and major components are formed from stainless steel stamping, resulting in exceptionally smooth flow channels. Shaft bushings and sleeves are made of wear-resistant hard alloy, ensuring extended service life and preventing secondary contamination. The shaft seal utilizes durable mechanical seals for leak-free operation. The motor features an aluminum housing, imported bearings, and Class F insulation.
These pumps operate smoothly with low noise, offering reliable performance, a compact and aesthetically pleasing design, light weight, and easy transportation and installation. They represent an ideal green, eco-friendly, and energy-saving pump solution.
For example:CDL F 4 – 160
CDL: Stamped light-duty vertical multistage pump
F: (Omitted for standard type) Wetted parts made of stainless steel 304 or 316
4: Rated flow rate (m³/h)
160: Number of stages × 10
The standard type is suitable for liquid transfer, circulation, and boosting of cold/clean hot water and softened water.
The stainless steel type can also handle slightly alkaline water, demineralized water, distilled water, swimming pool water, and liquids containing chlorides (note: allowable liquid temperature must be reduced for these applications).
1.Municipal water supply and pressure boosting
2.Industrial circulation and processing systems
3.Boiler feed water and condensate systems
4.Environmental water treatment and reverse osmosis systems
5.Agricultural irrigation and dewatering
5.Industrial plant cleaning and various washing operations
6.(Others) Many specialized uses
