Product Overview

The XBC-type diesel-engine fire pump unit is a newly developed product independently researched and manufactured in response to the market demand and usage characteristics of fire pumps for building fire protection in China. This series of products features high efficiency, long service life, and high reliability (with no risk of seizing upon startup after prolonged periods of inactivity). It is currently the preferred choice for fire pumps used in construction projects and sprinkler systems across China. The product’s performance complies with the performance requirements and test methods specified in GB 6245-2006 “Fire Pumps.” This product is suitable for conveying clean water or liquids with physical and chemical properties similar to water, provided that the temperature does not exceed 80°C and the liquid contains no solid particles. While meeting the requirements of fire-fighting conditions, it also takes into account the operational needs of domestic and industrial water supply. The product can be used either in stand-alone fire-water supply systems or in shared fire and domestic water supply systems. It is applicable to a wide range of scenarios, including building, municipal, industrial and mining, water supply and drainage, marine, and field operations. An important advantage is that when the power supply suddenly fails and the electric fire pump cannot start, the diesel-engine fire pump will automatically activate and take over emergency water supply.

Product Parameters

The XBC-type diesel-engine fire pump consists of a diesel engine and a fire pump. The pump unit is a horizontal, double-suction, single-stage centrifugal fire pump characterized by high efficiency, a wide performance range, safe and stable operation, low noise, long service life, and ease of installation and maintenance. It is designed for conveying clean water or other liquids whose physical and chemical properties are similar to those of water. By modifying the materials of the pump’s wetted parts, changing the sealing configuration, and adding a cooling system, the pump can also be used to convey hot water, oils, corrosive media, or media containing abrasive particles.

The new-generation product also features an LCD display. Compared to traditional instrument monitoring, it enables remote monitoring, making it much easier to modify the equipment’s operating parameters and significantly boosting work efficiency while reducing the physical strain on staff. With its comprehensive performance and forward-thinking design, this equipment far surpasses other similar products on the market.
 

 

Main features of fire-fighting diesel engine pump units:

1. The electric pump serves as the primary fire pump and can automatically start based on the fire situation.

2. Equip with a constant-pressure pump to maintain stable network pressure;

3. The diesel engine pump serves as a backup fire pump and will automatically start in the event of a power failure to the fire protection system.

4. When the electric pump fails, the diesel engine pump starts up.

 

Working principle of fire-fighting diesel engine pump units:
The XBC-type diesel-engine fire pump features both its inlet and outlet located on the pump body. During maintenance, only the pump cover needs to be lifted off; the rotor assembly can then be moved for inspection and repair without having to disconnect the piping. This makes the maintenance process extremely convenient. Depending on the application requirements, the diesel engine can be installed either on the left or right end of the pump, facilitating on-site installation. Structurally, the axial dimension of the rotor assembly has been shortened, resulting in high shaft rigidity and ensuring more stable and reliable operation. The pump is equipped with a pump-body sealing ring, while the impeller sealing ring is available as an optional feature.

Working conditions: The allowable working pressure is 2.5 MPa. Based on the maximum pressure that the pump casing can withstand, the pump body and pump cover are made of ductile iron (2.0 MPa) or cast steel (2.5 MPa), among other materials.

1) Ambient temperature ≤ 50℃, medium temperature ≤ 80℃,

2) The medium’s specific gravity shall not exceed 1240 kg/m³.

3) The liquid level must be higher than the pump’s inlet; running the pump dry without liquid is strictly prohibited.

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.
