Description
Inquiry

Kenda KLS series single-stage double-suction split-case pump is a new generation of products developed by integrating advanced international double-suction pump technology with high-efficiency hydraulic models. Designed for municipal water supply, HVAC cooling systems, and industrial irrigation. Its axially split casing allows for easy access to internal components without disturbing piping—perfect for reducing downtime in critical applications.

Technical Advantages

Easy Maintenance: Featuring a horizontally split-case design, it allows for internal inspections and parts replacement without dismantling the inlet/outlet pipelines or the motor.

Smooth Operation: The symmetrical double-suction impeller design theoretically balances axial forces automatically, resulting in low vibration and noise during operation.

Flexible Configuration: Supports both horizontal and vertical installation (for small models); sealing options include packing seals or mechanical seals; the direction of rotation can be customized upon request.

Long Service Life: The shaft is completely sealed and does not come into contact with the medium, effectively preventing corrosion and significantly extending the operating life.

Product Classification

Based on the medium being transported, the KLS series offers three professional configurations:

Standard Type: Designed for clean water and pure liquids with physical and chemical properties similar to clean water.

Wear-resistant Type: Specially engineered for silty rivers and water with high sand content (solid particles ≤ 80mg/L), offering higher efficiency and enhanced wear resistance.

Corrosion-resistant Type: Utilizes specialized corrosion-resistant materials and mechanical seals, suitable for transporting various chemically corrosive liquids.

Applications

The KLS Series is engineered for high-flow water transfer across diverse sectors:

Municipal: Urban water supply, boosting stations, and flood control.

HVAC: Cooling tower circulation and district heating systems.

Industrial: Process water for power plants, steel mills, and fire-fighting.

Agriculture: Large-scale irrigation and drainage projects.

FAQ

Q1: What are the maintenance benefits of the split-case design?

A: The axially split casing allows for easy access to internal components (impeller, bearings, seals) without disturbing the piping, significantly reducing downtime and maintenance costs.

Q2: Can this pump be installed vertically?

A: Yes. While horizontal is standard, the KLS series supports both horizontal and vertical configurations to suit your pump room layout.

Q3: What materials are available?

A: Beyond standard cast iron, we offer ductile iron, stainless steel (304/316), and bronze to handle corrosive or abrasive fluids.

Q4: Is it suitable for wastewater?

A: It is designed for clean water or liquids with similar properties. For fluids with minor solids, please contact us to customize the seal and material selection.
