Product Overview

The XBD-L Series Vertical Single-Stage Fire Pressure Stabilizing Pump is a compact vertical single-stage centrifugal pump designed specifically for fire protection pressure stabilizing applications. This integrated electromechanical pump unit maintains system pressure within the fire water network during standby conditions, preventing unnecessary activation of the main fire pumps due to minor pressure fluctuations.

The vertical inline design offers a compact footprint with straightforward installation directly in the pipeline, making it ideal 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 Single-Stage Fire Pressure Stabilizing Pump or XBD-LFire Pump.

Key Features

• High operating efficiency with optimised single-stage impeller design for reduced energy consumption during standby operation
• Integrated electromechanical design minimises installation footprint and simplifies pipeline integration
• Compact vertical inline arrangement suitable for direct pipeline installation
• Stable operating performance with rational structural design for long-term reliability
• Extended service life with quality materials and robust construction
• Reliable pressure maintenance for fire protection systems during standby conditions

Applications

• Hospital fire protection system pressure stabilising
• Commercial building fire hydrant and sprinkler system pressure maintenance

Customer Benefits

Energy-Efficient Standby Operation

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

Space-Saving Integrated Design

The integrated electromechanical vertical inline design enables direct pipeline installation with minimal additional space requirements, making the XBD-L Series ideal for installations with confined pump rooms.

Stable Pressure Maintenance

The single-stage impeller configuration 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.

Extended Service Life

The rational structural design and quality materials reduce component wear and extend maintenance intervals, lowering total cost of ownership over the pump service life.

Reliable Fire System Readiness

With flow rates from 1 to 120 L/s and pressures up to 1.52 MPa, the XBD-L Series provides dependable pressure stabilisation to ensure fire protection systems remain ready for immediate activation.

Wide Operating Range

With pressures from 0.32 to 1.52 MPa and outlet diameters from DN32 to DN250, the XBD-L Series covers a broad range of fire protection pressure stabilizing requirements across diverse building types.

Selection Guidance

To select the appropriate XBD-L 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

Installation and Maintenance

Installation Guidance

The pump should be installed directly in the pipeline 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. The integrated electromechanical design enables straightforward inline installation.

Pre-Start Inspection

Before starting the pump, confirm the following:

• Pump is securely mounted and properly aligned in the pipeline
• Pipeline connections are complete and properly sealed
• 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 120 L/s
• Pressure range from 0.32 to 1.52 MPa
• Motor powers from 0.75 to 200 kW
• Rotational speed: 2900 r/min
• Outlet diameters from DN32 to DN250
• Integrated control panels with automatic pressure monitoring and pump cycling
