Product Overview

The XBD-CDL Series Vertical Multistage Fire Pressure Stabilizing Pump is a compact vertical multistage centrifugal pump designed specifically for fire protection pressure stabilizing applications. This pump maintains system pressure within the fire water network during standby conditions, ensuring immediate water availability when the main fire pumps are activated.

The multistage impeller configuration delivers high pressure from a compact vertical footprint, making it suitable for installations with limited pump room space. Depending on regional terminology, it may also be referred to as a Fire Jockey Pump, Fire Pressure Maintenance Pump, Vertical Multistage Fire Stabilizing PumpXBD-CDL.

• Low-noise operation suitable for installations in or near occupied buildings
• Multistage impeller arrangement delivers high pressure within a compact vertical unit
• Stable operating performance with rational structural design for long-term reliability
• Straightforward maintenance access with simplified service procedures
• Reliable pressure maintenance for fire protection systems during standby conditions

Applications

• Fire hydrant system pressure stabilisation in residential and commercial buildings
• Automatic sprinkler system pressure maintenance in office complexes and hotels
• Water mist fire suppression system pressure stabilisation
• Fire protection water network pressure maintenance for factories and industrial facilities
• Hospital fire protection system pressure stabilising
• Commercial building fire hydrant and sprinkler system pressure maintenance

Customer Benefits

Energy-Efficient Standby Operation

The hydraulically optimised impeller design and efficient motor selection reduce power consumption during continuous standby operation, lowering utility costs over the pump service life.

Low-Noise Performance

The vertical multistage design and precision-balanced rotor assembly minimise operational noise, making the XBD-CDL Series suitable for installations in or near occupied buildings and sensitive environments.

Compact Space-Saving Design

The vertical arrangement requires significantly less floor space than equivalent horizontal multistage pumps, making the XBD-CDL Series suitable for pump rooms with limited installation area.

Stable Pressure Maintenance

The multistage impeller arrangement provides consistent pressure output to maintain the fire water network within the required pressure range during standby conditions, preventing unnecessary activation of the main fire pumps.

Easy Maintenance Access

The rational structural design and accessible component layout simplify routine inspection and servicing procedures, reducing maintenance time and costs.

Reliable Fire System Readiness

With flow rates from 1 to 5 L/s and pressures up to 1.58 MPa, the XBD-CDL Series provides dependable pressure stabilisation to ensure fire protection systems remain ready for immediate activation.

Selection Guidance

To select the appropriate XBD-CDL Series fire pressure stabilizing pump, please provide the following information:

• Required standby flow rate (L/s)
• Required system pressure (MPa or bar)
• Fire protection system type (hydrant, sprinkler, water mist)
• Building type and occupancy classification
• Available installation space and pump room dimensions
• Available voltage and frequency
• Applicable fire protection standards and codes

Final model selection should be confirmed according to the actual system pressure requirements and applicable fire protection standards.

Installation and Maintenance

Installation Guidance

The pump should be installed on a level, stable foundation with adequate clearance for inspection and maintenance. The inlet and outlet pipelines must be properly supported so that no external load is transferred to the pump connections.

Pre-Start Inspection

Before starting the pump, confirm the following:

• Pump is securely mounted and level
• Pipeline connections are complete and properly aligned
• Inlet and outlet passages are unobstructed
• Motor wiring is correct and terminals are secure
• Rotational direction matches the arrow indicated on the pump casing
• All fasteners are properly tightened

Routine Maintenance

Regular inspection should include:

• Checking mechanical seals for leakage
• Monitoring motor bearing temperature and vibration levels
• Verifying that the pump maintains the required system pressure
• Cleaning strainers and filters when necessary
• Inspecting all pipeline connections for signs of wear or leakage

Available Configurations

• Flow rates from 1 to 5 L/s
• Pressure range from 0.30 to 1.58 MPa
• Motor powers from 0.75 to 18.5 kW
• Rotational speed: 2900 r/min
• Different stage configurations for varying pressure requirements
• Integrated control panels with automatic pressure monitoring and pump cycling

FAQs

What is a fire pressure stabilizing pump?

A fire pressure stabilizing pump (also known as a fire jockey pump) maintains the required pressure in the fire water network during standby conditions, preventing unnecessary activation of the main fire pumps due to minor pressure fluctuations or small leaks.

What is the flow range of the XBD-CDL Series?

The XBD-CDL Series offers flow rates from 1 to 5 L/s, suitable for fire protection pressure stabilizing applications.

What is the pressure range?

Available pressures range from 0.30 to 1.58 MPa.

What fire protection systems can this pump serve?

It is suitable for fire hydrant systems, automatic sprinkler systems and water mist fire suppression systems in residential, commercial, industrial and institutional buildings.

Why use a multistage design for pressure stabilizing?

The multistage impeller arrangement achieves the required high pressure from a compact vertical unit, making it suitable for installations with limited pump room space while maintaining efficient standby operation.

What maintenance is required?

Regular maintenance includes checking mechanical seals for leakage, monitoring motor bearing temperature and vibration, verifying system pressure maintenance, and inspecting pipeline connections.
