Jiangsu Haifa Machinery Manufacturing Co., Ltd.

I. Product Overview

The BA Series BB5 pump is a high-pressure, multistage, radially split chemical process pump developed by Jiangsu Haifa Machinery Manufacturing Co., Ltd. in accordance with API 610 11th Edition. It features a single casing, radial split, segmental or barrel construction, and is suitable for conveying liquids under high-temperature, high-pressure, and severe operating conditions.

The BB5 pump is characterized by high head, high pressure resistance, and smooth operation, making it an ideal choice for critical applications in petrochemical, coal chemical, power generation, and other industries (e.g., high-pressure boiler feed, hydrogenation feed, lean/rich liquid service).

V. Performance Advantages

1. High Head Capability
   Multistage design achieves heads exceeding 1000 meters with a single pump, replacing multistage boosting solutions.

2. High-Pressure Stability
   Radially split casing ensures reliable sealing in high-pressure zones with no risk of leakage from a horizontally split joint.

3. High-Temperature Adaptability
   Centerline support structure prevents thermal distortion from affecting shaft alignment, suitable for continuous high-temperature operation.

4. Low Maintenance Cost
   Wear rings, hard-faced alloy bearings, and high-performance mechanical seals extend maintenance intervals.

5. API 610 Compliance
   Design, manufacturing, and testing meet international petrochemical industry requirements; directly interchangeable with imported products.
