Product Description
Engineered for flexibility, CDL/CDLF pumps deliver reliable performance in diverse liquid transfer applications, from municipal water supply to chemical processing. The CDL model ensures efficient pumping of non-corrosive fluids, while the CDLF version extends durability with corrosion-resistant materials, making it ideal for slightly acidic or alkaline environments.
Water supply: Water filter and transport in Waterworks, boosting of main pipeline, boosting in high-rise buildings.
Industrial boosting: Process flow water system, cleaning system, high-pressure washing system, fire fighting system.
Industrial liquid conveying: Cooling and air-conditioning system, boiler water supply and condensing system,.machine-associated purpose, acids and alkali.
Water treatment: Ultrafiltration system, reverse osmosis system, istillation system, separator, swimming pool.
Irrigation: Farmland irgation, spray irrigation, dripping irrigation.
Thin, clean, non-flammable and non-explosive liquidcontaining no solid granules and fibers.

Centrifugal Pumps
Application
Suitable for use with clean water and liquids that are not chemically aggressive towards the materials from which the pump is made.
As a result of their reliability and the fact that they are easy to use, these pumps are widely used in domestic and civil applications such as the distribution of water in combination with small and medium sized pressure sets, for transferring liquids and for the irrigation of gardens and allotments. The pump should be installed in an enclosed environment, or at least sheltered from inclement weather.

FAQs
1. What is a multi-function centrifugal pump? How does it differ from standard pumps?
Answer: A multi-function centrifugal pump is engineered for enhanced adaptability with these key features:
Media versatility: Handles clean water, mildly corrosive liquids, and fluids with微量 solids (requires special impeller design)
Modular construction: Allows functional adaptation by changing seal types (mechanical/gland packing) or wetted materials (stainless steel/cast iron)
Extended operating range: Covers wider flow/head ranges via VFD control or multi-stage design
Typical applications: Building water supply, industrial processes, HVAC systems, and mild wastewater
2.What are the energy-saving measures for multi-function pumps?
Answer: Key efficiency optimization methods include:
VFD control: Adjusts speed to match demand, eliminating throttle losses
3D-impeller design: CFD-optimized impellers improve efficiency by 5-15%
System matching: Ensure operation within ±10% of BEP (Best Efficiency Point)
Smart controls: Pressure/flow sensors enable PID closed-loop control
3. How to select pump configuration based on fluid characteristics?
