Designed in strict accordance with international firefighting equipment standards, this back-pull-out centrifugal pump offers maximum efficiency, easy maintenance, and long-term durability.

Product Application

The pump is suitable for fire protection in:

– Commercial buildings (offices, malls, and other commercial spaces)

– Industrial facilities (manufacturing plants and warehouses)

– Residential complexes (apartments and residential buildings)

– Municipal fire protection (public spaces and infrastructure)

Product Description

The CS Series (Bare Shaft Centrifugal Pump) and CSM Series (Electric Motor-Driven Pump Set) are industrial-grade fluid handling solutions engineered for global commercial, industrial, and municipal infrastructure projects. Utilizing an advanced single-stage, end-suction, top-centerline discharge configuration, these pumps combine superior hydraulic efficiency with heavy-duty structural integrity.

The CSM Series pumps are designed to meet the rigorous demands of fluid handling systems, offering both versatility and reliability across a range of applications. They are single-stage, end-suction, back pull-out pumps with a top centerline discharge.

  • Optimized Hydraulic Design: Engineered to achieve higher efficiency, reducing energy consumption and operating costs.

  • Smooth Operation: Dynamically balanced impeller ensures smooth, vibration-free operation, leading to extended service life and reduced noise.

  • Easy Maintenance: The back pull-out design allows for quick and easy maintenance without disrupting the pipe connections, minimizing downtime. Available in both gland-packed and mechanically sealed configurations, offering options for different operational environments.

Why Choose Our CS/CSM Series? (Our Advantages)

    • Standardized Modular Architecture: This ensures seamless integration into existing pipeline infrastructures and guarantees global interchangeability of components.

    • Advanced Back Pull-Out Design: Optimizes operational uptime. Maintenance teams can inspect or replace the impeller, shaft, and bearings without disconnecting the suction or discharge piping, significantly reducing maintenance overheads.

    • Heavy-Duty Reliability: Precision-cast components combined with a dynamically balanced rotating assembly minimize mechanical stress, ensuring stable, continuous S1 duty operation under high-pressure conditions up to 14 bar.

Product Application

Our heavy-duty centrifugal pumps are fully optimized for fire protection and liquid transfer in:

    • Fire Fighting Systems: Compliant with strict firefighting infrastructure needs for residential complexes, industrial plants, and public infrastructure.

    • Commercial Building Services: Reliable hot and cold water circulation, pressure boosting, and infrastructure HVAC support.

    • Agricultural & Primary Industries: Large-scale irrigation networks and clean water supply for modern livestock farming.

Packaging & Support

    • Flexible Drive Matching: The CS bare shaft model comes standard with a keyed shaft extension, ready to be paired with local electric motors or diesel engines. The CSM series arrives pre-aligned on a robust steel baseplate with an IP55 Class F motor.

    • Export Compliance: All units are securely packaged in international export standard wooden crates to ensure zero-damage transit. Full performance curves, CAD drawings, and test reports are available for project submittals.
