Product Overview

The XBD-W horizontal multistage high-pressure fire pump features a horizontal, single-suction, multistage, segmented design. It is a new-generation energy-saving multistage centrifugal pump series meticulously developed by our company specifically for the unique environments in which fire pumps are used. Its performance and technical specifications comply with the mandatory national standard GB6245-2006 “Fire Pumps.” Thanks to the adoption of an excellent hydraulic model, this pump series fully meets user requirements and boasts high efficiency, a wide performance range, and outstanding energy savings. Equipped with premium bearings and high-quality motors, the pump operates more safely and reliably, with low noise levels and minimal vibration. Moreover, by employing hydraulically balanced axial forces and eliminating the need for balance drums, the pump achieves even smoother operation.

Meaning of XBD Multistage High-Pressure Fire Pump Model Designations

Application of the XBD-W Horizontal Multistage High-Pressure Fire Pump:

The XBD high-pressure fire pump is suitable for supplying domestic water in high-rise buildings, fire-fighting water in high-rise buildings, water supply for factories and mines, enterprise water use, drainage, and circulating water for low-pressure boilers. The medium temperature ranges from 0℃ to 80℃, and the pump is designed to convey clean water or liquids with physical properties similar to water.

Introduction to the Structure of the XBD-W Horizontal Multistage High-Pressure Fire Pump:

The shaft of the XBD horizontal fire pump rotates driven by the electric motor, doing work on the liquid and increasing its energy. As a result, the required amount of liquid is continuously conveyed from the suction sump, through the pump’s inlet section, forward impeller, forward guide vanes, middle section, horizontal discharge outlet at the discharge section, transition pipe, secondary inlet section, reverse impeller, reverse guide vanes, and finally out through the vertical discharge outlet at the discharge section.

● The pump primarily consists of the following components: the suction section, the middle section, the discharge section, the secondary suction section, the forward guide vanes, the reverse guide vanes, the forward impeller, the reverse impeller, the shaft, the throttling and pressure-reducing device, the sleeve, the bearing housing, the transition pipe, and other parts. The middle section is connected to the suction and discharge sections via high-strength through-bolts. The sealing surfaces between the pump’s suction section, middle section, and discharge section all employ a hard metal seal lubricated with molybdenum disulfide grease. The rotor comprises the forward impeller mounted on the shaft, the throttling and pressure-reducing device, the reverse impeller, the shaft sleeve, and the bearing sleeve, among other components. The bearings adopt a “fixed-floating” dry-lubrication design: the drive end uses cylindrical roller bearings, while the tail end employs angular-contact ball bearings. The pump’s working chamber is composed of the suction section, the middle section, the discharge section, the secondary suction section, the forward guide vanes, the reverse guide vanes, and the transition pipe.
●The rotor assembly is sealed against the stationary parts by means of sealing rings, guide vane sleeves, and other components. When the wear on the sealing rings and guide vane sleeves has begun to affect the pump’s operational performance, they should be replaced promptly.
● There are two types of shaft seals: mechanical seals and packing seals. When a pump is equipped with a packing seal, the packing rings must be properly positioned, and the packing should be tightened to an appropriate degree—just enough to allow liquid to seep out drop by drop. All sealing components of the pump are housed within a sealed cavity, which is supplied with water at a certain pressure to serve as a water seal, provide water cooling, and offer water lubrication. A replaceable shaft sleeve is installed at the shaft seal area to protect the pump shaft. The pump allows bearing and seal replacement without dismantling the inlet and outlet pipelines.
● The pump is directly driven by the prime mover via an elastic pin coupling or a diaphragm coupling. When viewed from the direction of the prime mover, the pump rotates clockwise.
● The standard motor configuration is the Y3 series motor; in environments with flammable and explosive gases, the YB3 series explosion-proof motor is used.

What is your typical delivery time?

Models in stock can be shipped the next day at the latest. All others are custom-made, with lead times generally ranging from 7 to 90 days depending on the product size and project specifics. Please contact our sales manager for details: 0731-88632200 。

Do you have centrifugal pumps in stock?

Centrifugal pumps come in numerous models and configurations. Except for a small number of high-volume, standard models that are in stock, the vast majority are not stocked and are customized products. We need to select a pump based on your site's flow rate, head, media temperature, pH value, and installation conditions, etc., to determine the pump model and configuration before we can submit an order to the factory for production.

What information should I provide when requesting a quote?

Generally, to obtain an accurate quotation, we recommend providing us with the following information: pump flow rate, head, on-site operating voltage and frequency, temperature, pH value, and solid particle content of the fluid being conveyed, and on-site installation conditions (horizontal or vertical installation), etc.

If you are not sure, don't worry, our business managers will assist you in determining this.

What products do you mainly produce?

Zhonglian Pump Industry manufactures various large industrial centrifugal pumps. Main products include: self-balancing multi-stage pumps, multi-stage centrifugal pumps, single-stage centrifugal pumps, split-case pumps, chemical pumps, submersible pumps, pipeline pumps, long-shaft pumps, condensate pumps, etc.

Could you help me with the selection?

Certainly! If the water pump model is not selected accurately, there will be big problems. If you choose a smaller one, it won't meet your needs; if you choose a larger one, it will waste electricity and fuel, increasing your costs.

Why is it so slow to get a price quote?

Because centrifugal pumps are non-standard customized products with many models, the price range is also very large. Even for the same model, the price difference is also very large due to different materials and configurations. Taking the most common water pump accessory—the impeller—as an example, the price of a stainless steel impeller is several times that of a cast iron impeller. Therefore, we need to clarify the relevant information to give you an accurate price. Normally, if you provide relatively comprehensive information, we can quote within 5 minutes.
