CDLK Immersion Multistage Coolant Pump

The CDLK is a vertical immersion stainless steel multistage centrifugal pump (with the matching derivative model CDLKF). It belongs to the category of non-self-priming immersible pumps, where the electric motor is located on top and the multistage pump body operates vertically immersed inside a water tank or liquid vessel. Engineered as a high-pressure coolant pump, it provides reliable liquid circulation specifically tailored for machine tools and industrial cleaning operations.

Key Features

• Immersion Installation: The pump body is directly submerged into the coolant tank for self-cooling, requiring no external cooling lines. Features a minimal footprint that easily fits narrow water tanks on machine tools.

• Adjustable Head & Stable Pressure: The number of impeller stages can be adjusted to cover a head range from 6 m to 305 m, perfectly matching high-pressure cleaning and deep circulation water supply requirements.

• Durable & Easy Maintenance: Stainless steel construction resists corrosion from industrial coolants and cutting fluids. Optional dry-running, phase-loss, and overload protectors prevent motor damage from idling. Simple disassembly allows individual impeller replacement without dismantling the entire coolant pumpunit.

• Energy Saving & Low Noise: Optimized hydraulic design and multistage stamped impellers ensure high efficiency, reduced vibration, and low noise levels during multistage centrifugal pumpoperation.

Main Applications

• CNC Machining Industry: Coolant circulation and lubricant delivery for CNC machine tools, lathes, grinding equipment, machining centers, and EDM (Electrical Discharge Machining) systems.

• Industrial Cleaning: High-pressure washers, automated spray cleaning lines, and fluid filtration circulation systems.

• General Industrial Circulation: Chiller condensate loops, compact cooling units, hydraulic station oil supply, and small-scale water treatment filtration systems utilizing an immersible pump design.
