Product Overview

The XBD-L vertical multistage fire pump is a single-suction, multistage vertical centrifugal pump. It is a new type of fire-fighting product designed and developed in response to market demands, intended for conveying clean water or liquids with physical and chemical properties similar to water (but without corrosive substances) at temperatures below 80℃. This pump is specifically designed for fire-fighting water supply applications. It is suitable for various settings, including residential buildings, hotels, office buildings, commercial complexes, factories, hospitals, and other similar locations.

 Meaning of the XBD-L Vertical Multistage Fire Pump Model

 
 
Structural features of the XBD-L vertical multistage fire pressure stabilization pump:
 
The XBD-L vertical fire pump features a vertical, multistage, sectional design. The suction section, middle section, and discharge section are joined together using four bolts. The suction port is located on the suction section at the lower end of the pump, while the discharge port is situated on the discharge section at the upper end of the pump. Depending on installation and operational requirements, the discharge section can be rotated in four different orientations—90°, 180°, or 270°. Unless otherwise specified by the user, the discharge section is typically installed at the 180° orientation.
 
The main components of the pump include: the suction section, the middle section, the discharge section, guide vanes, impeller, shaft, balance drum, balance sleeve, and sealing rings. The majority of the pump’s axial force is borne by the balance drum, while the remaining residual axial force is supported by the radial thrust ball bearing located at the upper end. According to user requirements, the pump seal can be either a packing seal or a mechanical seal.
 
Viewing the pump from the motor end, the pump rotates counterclockwise. The entire rotor assembly of the pump is supported by a radial thrust ball bearing at the upper end and a hydrodynamic bearing at the lower end. The radial thrust ball bearing is lubricated with calcium-based grease.
 
The installation steps for the XBD-L type multistage fire pump include placing the pump on the foundation, aligning it, and connecting the pump piping.
 
       Installation precautions:
 
1. The axis lines of the motor and the pump must lie in the same plane and be aligned in a straight line.
 
2. A certain gap should be maintained between the motor coupling and the pump coupling; this gap should be 3–5 mm.
 
3. The pressure gauge on the inlet and outlet pipelines should ideally be installed at a location that is twice the diameter away from the flange. It must not be installed next to bends or valves to avoid interference from unstable flow.
 
4. The inlet and outlet pipes should be equipped with supports to reduce the additional forces exerted on the pump by the piping and to minimize vibrations in the piping system.

Q

What is your typical delivery time?

A

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 。

Q

Do you have centrifugal pumps in stock?

A

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.

Q

What information should I provide when requesting a quote?

A

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.

Q

What products do you mainly produce?

A

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.

Q

Could you help me with the selection?

A

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.

Q

Why is it so slow to get a price quote?

A

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.
