Product Overview

The XBD-CDS Series Horizontal Split-Case Fire Pump is a high-performance fire protection solution featuring a horizontal split-case double-suction impeller design. this pump delivers flow capacity and pressure for comprehensive fire suppression systems.

Engineered with a horizontally split casing that allows the upper half to be removed without disturbing suction and discharge piping, the XBD-CDS Series provides maintenance accessibility. The double-suction impeller design ensures balanced hydraulic forces, minimizing axial thrust and extending bearing life while delivering smooth, vibration-free operation.

Key Features

1. Horizontal Split-Case Design – The casing splits horizontally along the centerline, allowing complete access to internal components without removing the pump from the pipeline.
2. Double-Suction Impeller – The balanced double-suction impeller design eliminates axial thrust, reducing bearing load by up to 80% compared to single-suction pumps.
3. High Flow and Pressure Capacity – Engineered to deliver flow rates from 10 to 120 L/s with discharge pressures up to 2.4 MPa (350 psi), meeting the most demanding fire protection system requirements for large facilities and high-rise buildings.
4. Premium Material Construction – Available in cast iron, bronze-fitted, or all-bronze configurations to suit various water quality conditions and corrosion requirements.
5. Compliance with International Standards – Designed and tested in accordance with NFPA 20, UL/FM listing requirements, GB 6245, and EN 12845 standards, ensuring global acceptance and compliance with local fire codes.
6. Flexible Drive Options – Compatible with electric motors, diesel engines, and steam turbines to provide redundancy and ensure fire pump operation during power outages or emergency scenarios.

Applications

1. Fire Hydrant Systems
2. Automatic Sprinkler Systems
3. Water Mist Fire Suppression

Selection Guidance

Selecting the right XBD-CDS Horizontal Split-Case Fire Pump requires careful consideration of system requirements and application specifics:

1. Determine System Flow Requirements – Calculate total fire water demand based on the most demanding scenario: simultaneous operation of fire hydrants, sprinkler systems, and water mist systems. Consider the hazard classification and occupancy type per NFPA 13, NFPA 14, or local fire codes.
2. Calculate Required Pressure – Determine the total dynamic head including static elevation, friction losses in piping, and residual pressure required at the most remote hose connection or sprinkler. Include a 10-15% safety margin for system degradation over time.
3. Select Appropriate Materials – For standard freshwater applications, cast iron construction is suitable. For corrosive water sources or seawater applications, specify bronze-fitted or all-bronze pumps. Consider water quality analysis when selecting materials.
4. Choose Drive Configuration – Electric motor drive is standard for reliable power supply. Diesel engine drive provides redundancy during power outages and is required by many fire codes for critical facilities. Consider dual-drive configurations for maximum reliability.
5. Evaluate Space Constraints – The horizontal split-case design requires adequate clearance for motor removal and maintenance access. Ensure sufficient space for piping connections, valve operation, and future maintenance. Consider the pump room layout and access routes for equipment installation.
6. Consider Future Expansion – Select a pump with capacity for potential system expansion. The XBD-CDS Series offers flexibility for future increases in fire protection demand without requiring pump replacement.

FAQs

Q1: What is the difference between a horizontal split-case pump and an end-suction pump?

A horizontal split-case fire pump (also called split case fire pump or double suction fire pump) has a casing that splits horizontally along the shaft centerline, allowing the top half to be removed for maintenance without disturbing the piping.

Q2: Why choose a double-suction impeller design?

The double-suction impeller design provides balanced hydraulic forces that eliminate axial thrust, reducing bearing load by up to 80% compared to single-suction impellers.

Q3: What is the expected service life of the XBD-CDS Series?

With proper installation, operation, and maintenance, the XBD-CDS Series Horizontal Split-Case Fire Pump provides 20-25 years of reliable service.

Q4: Can the XBD-CDS Series be used with seawater or corrosive water sources?

Yes, the XBD-CDS Series is available in all-bronze construction specifically designed for seawater and corrosive water applications.

Q5: What certifications does the XBD-CDS Series have?

The XBD-CDS Series is UL/FM listed for fire pump service, CE marked for European markets, and compliant with NFPA 20, GB 6245, and EN 12845 standards.

Q6: How do I select the right pump size for my application?

Pump selection requires calculation of system flow demand and total dynamic head.
