API 610 Cargo Pump Arrangement with Eureka BB2
Eureka’s API 610 Cargo Pump Systems are engineered for high-efficiency cargo transfer in FPSOs, chemical plants, and industrial applications. Based on the robust BB2 pump design, the system offers long service intervals, reliable operation, and full compliance with API 610 and API 682 standards. With multiple configuration options, pressurized barrier-fluid sealing systems, and integrated control solutions, this cargo handling package delivers safe, efficient, and fully optimized pump room performance.
Main Features & Benefits
- Single pump design meets discharge pressure requirements on its own
- API 610-compliant for high-pressure cargo transfer
- Wide material selection in accordance with API 610
- Supports high nozzle loads for structural integrity
- Low NPSH operation prevents cavitation and increases pump life
- Variable speed operation via hydraulic coupling or frequency converter
- Fully integrated system with cargo, stripping, ballast, and tank-washing pumps and drivers
- Eureka control system for full monitoring and control
- Pressurized API 682 double mechanical seal prevents hydrocarbon leakage
- Safe FPSO offloading with speed control to match tank level and NPSH
Description
The system consists of one or more API 610 BB2 centrifugal pumps driven by fixed or variable speed motors, typically arranged in horizontal or vertical configurations, depending on the layout. The motor and pump can be installed in separate compartments, requiring a gas-tight transmission or coupling. Each system is engineered to deliver optimized flow, pressure, and control during cargo transfer operations.
Key Design Features:
- Pump type: Single-stage, double-suction, double volute, radially split BB2 design
- Drive options: Fixed speed, hydraulic coupling, or VFD (variable frequency drive)
- Mechanical seal: API 682 double mechanical seal system with pressurized barrier fluid (Plan 53B)
- NPSH control: Pump speed reduces as tank empties to avoid cavitation
- Possible configuration: 3 × 50% or 4 × 33% pumps, one standby always available
- Optional: Priming system on suction side
