CDL/CDLF Stainless Steel Vertical Multistage Centrifugal Pump

The CDL series is a non-self-priming vertical multistage centrifugal pump, engineered for handling thin, non-explosive liquids. Unlike horizontal pumps, its vertical inline design allows the suction and discharge ports to be positioned on the same horizontal plane (base level), significantly reducing the installation footprint.

CDL/CDLF Stainless Steel Vertical Multistage Centrifugal Pump Key technical configurations include:

Wetted Parts: High-grade AISI 304 or 316L stainless steel, formed via advanced welding and stamping processes to ensure smooth hydraulic surfaces and minimal friction loss.

Motor Connection: Standardized block design. The pump head and motor are coupled via a split-type sleeve, allowing for easier maintenance without dismantling the entire pipework.

Shaft Seal: A cartridge-type mechanical seal is standard. This design simplifies replacement and protects the shaft from wear during high-pressure cycles.

Engineers typically specify CDL/CDLF pumps for systems where pressure consistency is more critical than high flow volume.

Boiler Feed Systems: Capable of handling high-temperature condensate return and providing the necessary head to overcome boiler backpressure.

Reverse Osmosis (RO) Filtration: Used as high-pressure booster pumps in water treatment skids, ensuring the permeate flow remains stable across membranes.

Industrial Wash-Down: Ideal for high-pressure cleaning systems in food processing or automotive assembly lines where detergent compatibility is required (CDLF version).

HVAC Pressure Boosting: Maintaining constant pressure in high-rise building secondary water supply and cooling towers.

Hydraulic Precision: The impellers are laser-welded, not cast. This results in a much higher MEI (Minimum Efficiency Index) compared to traditional cast iron pumps, leading to direct energy savings on 24/7 operations.

Space-Saving Geometry: In tight mechanical rooms or containerized treatment plants, the vertical orientation saves up to 70% of floor space compared to horizontal multistage units.

Modular Pressure Stages: We can customize the number of impellers (stages) to meet your exact Duty Point (Flow vs. Head), preventing the common issue of "over-specifying" which wastes power.

Low Vibration Stability: The pump base is heavy-duty cast iron (with SS internals), providing a low center of gravity that minimizes pipework vibration and extends bearing life.
