**General Description of Split Case Pump for Petrochemical (API 610 Standard)**
The APS series single-stage double-suction split case centrifugal pump is a newly developed product designed in accordance with the American Petroleum Institute standard API 610. It is widely used in the transportation of crude oil, refined oil, and other liquid chemical products across various industrial applications.
This pump series follows the latest versions of industry standards and specifications during its design, manufacturing, and testing phases. The primary standard it adheres to is:
**Executive Standard:**
API 610 – *Centrifugal Pumps for Industrial Use in Petroleum, Petrochemical, and Natural Gas Industries*
**Technical Parameters of APS Split Case Pump:**
| Inlet and Outlet Size (mm) | Capacity (m³/h) | Head (m) |
|----------------------------|------------------|-----------|
| 80–400 | 22–3200 | 7–216 |
**Pump Model Description:**
For example, **APS200-420**
- **APS** – Single-stage, double-suction, split-case centrifugal pump designed according to API 610
- **200** – Outlet diameter (in mm)
- **420** – Impeller diameter (in mm)
**Key Technical Advantages:**
1. **Long Service Life:** Designed for over 20 years of service (excluding wear parts), with continuous operation designed for more than 3 years.
2. **High Performance:** When using a larger impeller or different hydraulic model, the pump head increases by more than 5% at rated speed.
3. **Over-speed Capability:** Can run continuously at 105% of rated speed and briefly at higher speeds in emergency situations.
4. **Cavitation Protection:** Features an NPSH safety margin to reduce damage from cavitation, fluid return flow, and separation.
5. **Efficiency Range:** Operates within 70–120% of the impeller’s best efficiency point, with the rated flow between 80–110%.
**Maintenance-Friendly Design:**
The axial split case structure allows easy access for maintenance without disassembling the entire pump. Seal and bearing replacements can be done without opening the casing, and internal components can be checked without removing the motor or piping.
**Comprehensive Monitoring System:**
To ensure safe and efficient operation, the APS pump can be equipped with optional monitoring systems such as:
- Bearing temperature monitoring
- Vibration monitoring
- Leakage detection system
