Description
The Serie CLC represents an evolution in centrifugal pumping technology, specifically designed for applications that require higher heads and greater structural rigidity. As a “Close-Coupled” (CLC) unit, the pump is directly mounted to the motor, resulting in a more compact footprint and eliminating the need for complex shaft alignment. This makes the Serie CLC an excellent choice for skid-mounted systems and tight industrial installations.
From a technical standpoint, the Serie CLC features a reinforced casing and a heavy-duty impeller capable of sustaining higher discharge pressures than standard models. The internal geometry is precision-machined to reduce vibration and noise, contributing to a quieter work environment and a longer service life for the motor bearings and mechanical seals. It is built to withstand the “water hammer” effects and thermal shocks common in industrial steam and cooling cycles.
The Serie CLC is also highly customizable. Depending on the chemical nature of the fluid, it can be equipped with various mechanical seal faces—such as Silicon Carbide or Tungsten Carbide—and specialized elastomers like Viton or EPDM, ensuring total compatibility with aggressive industrial fluids.
Key Features of the Serie CLC
- Close-Coupled Design: Compact, space-saving construction with no alignment required.
- High-Pressure Capability: Reinforced housing for superior head performance.
- Vibration Damping: Precision balancing for smooth and quiet operation.
- Robust Shaft Construction: Minimizes deflection to protect the seal integrity.
- Industrial Finish: Durable coatings or polished options for various environments.

Uses and Applications of the Serie CLC
- Industrial HVAC: Circulation of chilled water and heating fluids.
- Process Engineering: Moving chemicals and solvents in manufacturing plants.
- High-Pressure Cleaning: Feeding industrial pressure washers and spray balls.
- Petrochemicals: Transfer of light oils and refined petroleum products.
- Boiler Feed: Pumping condensate and feed water in steam systems.
Usage and Maintenance Recommendations for Serie CLC
- Regularly check the motor cooling fan for obstructions to prevent overheating.
- Monitor the discharge pressure gauge to ensure the pump is operating on its intended curve.
- Use the integrated drain ports to empty the pump during long shutdown periods in cold climates.
- Inspect the connection between the pump and motor for any signs of seal leakage.
Frequently Asked Questions about Serie CLC
Does the close-coupled design make it harder to repair?
No, it actually simplifies the process as there are no external couplings or guards to manage. The back-pull-out design allows for easy maintenance of the liquid end.
Can it be used for flammable liquids?
Yes, provided it is equipped with the appropriate ATEX-certified motor and non-sparking mechanical seals. Always consult the safety data sheet of the fluid.
What is the advantage of the CLC over the standard CL?
The CLC is generally more robust for higher pressure applications and its compact design makes it much easier to integrate into machinery or tight spaces where alignment is difficult to maintain.
