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 conveying 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 in industrial and mining water supply and drainage. 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 for installation, with the center of gravity aligning 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 a horizontal direction, simplifying pipeline connections.

3. The multi-level design can be configured to suit requirements, with the inlet and outlet options for installation in the same direction or at 90, 180, or 270 degrees 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 offered by other types of pumps.

5. The pump rotor features a smaller degree of curvature, ensuring smooth operation, low vibration, minimal noise, and a long service life.

● Main Application

The XBD-L(W) type fire pump is mainly used for boosting water pressure in fire system pipelines. It is also suitable for industrial and urban water supply and drainage, boosting water pressure in high-rise buildings, long-distance water supply, heating, bathrooms, boiler water circulation for heating and cooling, air conditioning refrigeration system water supply, and equipment matching in various applications.

Structural Description

The XBD-L(W) single-suction, single-stage fire pump consists of two parts: the motor and the pump, both of which are coaxial. The pump structure includes the pump body, impeller, pump cover, and mechanical seal. The pump's inlet and outlet are on the same horizontal axis and have the same diameter, making installation and removal extremely convenient with minimal floor space required. The pump is equipped with a mounting base for easy installation and enhanced stability during operation. The pump uses mechanical seals 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 matching.

The XBD-L(W) single-suction multi-stage segmented 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, with a rigid overall connection that requires no adjustment during operation. The pump is composed of a stator section and a rotor section. The stator section includes an inlet section, a middle section, guide vanes, an outlet section, and a stuffing box, among other components. To prevent stator wear, sealing rings and balancing sleeves are installed on the stator, which can be replaced with spare parts upon wear. The rotor section is made up of a 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 borne by the balancing drum, with the remaining small portion of residual shaft downward force being supported by the angular contact ball bearings. The junction surfaces of the inlet, middle, and outlet sections are sealed using paper gaskets that are tightened for a secure fit, which can be selected according to the user's needs.
