Product Description
I. Product Overview
The BB4 pump is a horizontal, radially split, single-casing, multistage between-bearing centrifugal pump manufactured in strict accordance with API 610 (ISO 13709) latest standard. Featuring a ring-section (sectional) casing structure and dual-bearing support on both shaft ends, the BB4 design delivers exceptional mechanical rigidity, ultra-high pressure resistance, and stable rotor operation for long-cycle continuous industrial service.
Different from single-stage OH series pumps and double-barrel BB5 pumps, BB4 is a cost-effective high-pressure multistage solution optimized for medium-to-extreme head working conditions. It is widely adopted for high-pressure fluid transportation in petroleum refining, petrochemical, power generation, and water injection projects, trusted for zero-failure continuous operation under harsh process environments.
II. Product Features
- Fully compliant with the latest API 610 industrial heavy-duty standards for high-pressure process systems
- Ultra-high head and high-pressure resistance, stable performance for 24/7 long-cycle continuous operation
- Diversified material solutions for high temperature, corrosion and slight abrasion working media
- Advanced thrust balance system and dual-bearing structure for low vibration and high mechanical stability
- Standardized modular design, high versatility of spare parts and low life-cycle maintenance cost
- Optimal cost-effective high-pressure multistage pump, ideal for replacing expensive BB5 barrel pumps in medium high-pressure scenarios

IV. Structural Description
- Standard BB4 Between-bearing Multistage Structure
Horizontal radially split ring-section casing design with symmetric dual-bearing support at both shaft ends. This structural layout minimizes shaft deflection and vibration, ensuring excellent dynamic stability under ultra-high pressure and variable load conditions. - Multi-stage Superimposed Pressurization
Multiple impellers are arranged in series to realize step-by-step pressurization, achieving ultra-high lift with stable hydraulic performance. Optional back-to-back impeller arrangement effectively balances residual axial thrust and improves operation stability. - Professional Axial Thrust Balance System
Equipped with high-precision balance drum or balance disc device, which automatically offsets most axial hydraulic thrust generated by multistage pressurization. It reduces bearing load and greatly extends the service life of bearings and mechanical seals. - High-pressure Resistant Casing Design
Integral sectional casing with thick-wall structure and standard API corrosion allowance. Reinforced through-bolt connection ensures tight sealing and no deformation under extreme high-pressure working conditions. - Full API Mechanical Seal Compatibility
Supports all standard API seal flush plans (11, 13, 21, 23, 32, 52, 53, 62). Multiple seal configurations including single seal, tandem seal and double seal are available for high-temperature, flammable, toxic and corrosive media to achieve zero leakage operation. - Heavy-duty Lubrication & Bearing System
High-strength precision rolling bearings with optional grease lubrication or forced oil lubrication. It supports long-term high-speed and high-load operation with low noise and low wear. - Standardized & Maintainable Structure
Modular stage structure with highly interchangeable spare parts. Reasonable disassembly procedure simplifies daily maintenance without integral pipeline removal, reducing equipment downtime and operation costs. - Full API 610 Compliance
Complete with vent ports, drain ports, wear protection rings, anti-rotation devices, and standardized cooling & flushing auxiliary pipelines, fully meeting the strict requirements of petrochemical and power heavy-duty working conditions.
