Product Overview

The XBD-GDL Series Vertical Multistage Fire Pump is a vertically arranged multistage centrifugal pump designed for fire protection applications requiring elevated head. The multistage impeller configuration delivers high pressure across multiple stages within a compact vertical footprint, making it suitable for high-rise building fire protection and installations with limited pump room space.

This fire pump provides reliable fire protection water supply for fire hydrant systems, automatic sprinkler systems and water mist suppression systems. Depending on regional terminology, it may also be referred to as a Vertical Multistage Fire Pump, High-Head Fire Pump, Vertical Multistage Fire Pump or XBD-GDLFire Pump.

Key Features

• High operating efficiency with optimised hydraulic design for reduced energy consumption during fire pump test runs
• Compact vertical structure occupies minimal floor space compared to horizontal multistage pumps
• Stable operating performance with rational structural design for long-term reliability
• Rational impeller arrangement delivers high head within a single integrated vertical unit
• Extended service life with quality materials and robust construction
• Suitable for both fire protection and high-pressure water supply applications

Applications

• Fire hydrant fire suppression systems in high-rise residential and commercial buildings
• Automatic sprinkler fire protection systems requiring elevated supply pressure
• Water mist fire suppression systems
• Fire protection water supply for office complexes, hotels and commercial buildings
• Industrial facility fire protection including factories
• Hospital fire protection systems requiring reliable high-pressure water supply

Customer Benefits

Energy-Efficient Operation

The hydraulically optimised impeller design and efficient motor selection reduce power consumption during fire pump test runs and emergency operation, lowering operating costs over the pump service life.

Space-Saving Vertical Design

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

High-Head Capability

The multistage impeller configuration delivers pressures up to 2.2 MPa, making the XBD-GDL Series suitable for high-rise building fire protection and applications requiring elevated supply pressure.

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.

Stable Fire System Performance

The multistage impeller arrangement provides consistent head and flow output across a wide operating range, ensuring reliable fire protection water supply during emergency events.

Wide Operating Range

With flow rates from 5 to 80 L/s and pressures from 0.32 to 2.2 MPa, the XBD-GDL Series covers a broad spectrum of fire protection system requirements.

Selection Guidance

To select the appropriate XBD-GDL Series vertical multistage fire pump, please provide the following information:

• Required flow rate (L/s)
• Required pressure (MPa or bar)
• Fire protection system type (hydrant, sprinkler, water mist)
• Building type and occupancy classification

• Available voltage and frequency
• Required duty point on the pump curve
• Applicable fire protection standards and codes

Final model selection should be confirmed according to the actual duty point, system 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 access. 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 flow and pressure during test runs
• Cleaning strainers and filters when necessary
• Inspecting all pipeline connections for signs of wear or leakage

Available Configurations

• Flow rates from 5 to 80 L/s
• Pressure range from 0.32 to 2.2 MPa
• Motor powers from 4 to 160 kW
• Rotational speed: 2900 r/min
• Outlet diameters from DN50 to DN250
• Different stage configurations for varying pressure requirements
