Product Description
Model Code Explanation
Ⅰ. Overview
XBD Series (Vertical Long Shaft) Deep-Well Fire Pump Units are independently developed and manufactured by our company. They strictly comply with GB 6245-2006 and have passed the China Compulsory Certification for Fire Protection Products (3C Certification). They are specially designed for various fire-fighting water supply systems.
Based on the RJC Series Long-Shaft Deep-Well Pump platform, this pump adopts advanced hydraulic models from overseas, a brand-new structural design, and multiple advanced processes (including Ashland core-making and epoxy coating on flow channels). The product is manufactured in accordance with Hydraulic Institute (HI) Standards, achieving internationally advanced performance levels. All models are classified as energy-efficient deep-well fire pump units.
Ⅱ. Product Features
- Advanced Hydraulic Model + New Manufacturing Technology
Uses a high-efficiency hydraulic model combined with new processes such as Ashland core-making and epoxy coating of impeller flow channels. Features optimized structure, excellent performance, and longer service life. - High-Efficiency Multistage Pump, Significant Energy Savings
Efficiency is 2–8% higher than similar domestic pumps; the efficiency curve is flatter with a wider high-efficiency zone, expanding the operating range by 10–20%. For the same flow and head, power consumption is lower, reducing electrical control investment and operating costs. - Labyrinth-Type Sand Prevention Structure
The labyrinth-style sand-proof ring effectively prevents sand particles from entering the bearing, improving reliability. - Double Bronze Bearing Support for Smoother Operation
Both impeller shaft and motor shaft use bronze bearings, keeping shaft radial runout within 0.13 mm, ensuring smooth and low-noise operation. - Reasonable Pump Base Design, Easy Maintenance
The pump base has a wide opening, an aesthetic appearance, and allows convenient inspection and packing replacement. - Integrated Connection Structure – Small Footprint, High Stability
Vertical long-shaft integrated connection design enables easy installation, small footprint, convenient commissioning, and low failure rate. - Multiple Stainless Steel Materials Available
Materials such as ASTM 304, 316, 416 can be selected according to operating conditions, suitable for various media and special requirements.
Ⅲ. Applications
The XBD (Vertical Long Shaft) Deep-Well Fire Pump Unit is suitable for:
- Industrial and mining enterprises
- Urban buildings and high-rise buildings
- Large engineering fire-fighting systems
- Fire hydrant systems
- Automatic sprinkler systems
Capable of handling clean water and liquids with similar chemical properties to water. It is also applicable to domestic & industrial water supply systems, municipal water supply and drainage systems.
Ⅳ. Main Component Description
1. Motor: Special motor for deep-well pumps (YLB type) or solid-shaft motor.
2. Pump base assembly: Connects the discharge pipe, supports the motor, and changes the flow direction.
3. Discharge pipe assembly: Flanged structure; upper short pipe connects to the pump base, lower short pipe connects to the pump bowl assembly.
4. Pump bowl (working) assembly: Converts mechanical energy into kinetic and potential energy of the liquid.
5. Strainer assembly: Prevents large solid particles or floating debris from entering the pump suction inlet, avoiding blockage of the pump flow channel.
