Product Overview

The XBD-L(W) fire pump is available in two types: single-suction single-stage and single-suction multi-stage segmented. It is designed for transporting clean water and liquids with physical and chemical properties similar to water, free of solid particles. Primarily used for boosting water pressure in fire protection systems, it can also be applied for drainage and water supply in factories and mines. The flow rate range is 5~80L/s, the pressure range is 0.2~2.25MPa, the power range is 1.5~200kW, and the diameter range is Φ50~Φ250mm.

Product Features

The pump features a compact structure, small size, and attractive appearance. Its vertical design ensures minimal footprint and its center of gravity aligns with the center of the pump base, thereby enhancing the pump's operational stability and lifespan.

2. Both pump suction and discharge ports are in the horizontal direction, simplifying pipeline connections.

3. The multi-stage model can be customized as needed, with the inlet and outlet capable of being installed in the same direction or at 90°, 180°, or 270° to accommodate various connection scenarios.

4. Pump pressure can be adjusted by increasing or decreasing the number of pump stages and cutting the impeller's outer diameter to meet requirements, without altering the installation footprint – a feature not available in other types of pumps.

5. The pump rotor features minimal eccentricity, ensuring smooth operation, low vibration, minimal noise, and a long service life.

● Main Application

XBD-L(W) fire pumps are primarily used for increasing water pressure and supply in fire system pipelines. They are also suitable for industrial and urban water supply and drainage, high-rise building water pressure supply, long-distance water supply, heating, bathrooms, boiler hot and cold water circulation, air conditioning refrigeration system water supply, and equipment matching.

● Model Significance

● Structural Description

The XBD-L(W) single-suction single-stage fire pump consists of two parts: the motor and the pump, which are coaxial. The pump structure includes the pump body, impeller, pump cover, and mechanical seal, among other components. The pump's inlet and outlet are on the same horizontal axis and have the same diameter, making it extremely easy to install and dismantle, with minimal floor space required. The pump is equipped with a mounting base for easy installation and increased operational stability. The pump features mechanical sealing for reliable sealing and zero leakage. The axial force of the pump is balanced by a balancing ring on the impeller. The pump's inlet and outlet flanges are designed for a pressure of 1.6 MPa, facilitating pipeline installation.

The XBD-L(W) type single-suction multi-stage fire pump consists of two parts: the motor and the pump. The motor is a Y, Y2 type three-phase asynchronous motor. The pump and motor are connected by a coupling, forming a rigid assembly that does not require alignment during operation. The pump is composed of the stator part and the rotor part. The stator part includes the inlet section, middle section, guide vanes, outlet section, stuffing box, and other components. To prevent stator wear, sealing rings and balancing sleeves are installed on the stator, which can be replaced with spare parts if worn out. The rotor part is made up of the shaft, middle wheel, and balancing drum. The lower end of the rotor is equipped with a water-lubricated bearing, while the upper end features angular contact ball bearings. The majority of the pump's axial force is carried by the balancing drum, with the remaining small portion of residual shaft downward force being supported by the angular contact ball bearings. The joint surfaces of the inlet section, middle section, and outlet section are sealed using paper gaskets, which are tightened for sealing. Users can select these as needed.
