**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 by our company, 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 series of pumps follows the latest versions of industry standards and specifications during design, production, and testing. Key standards include:
- **Executive Standard:** API 610 – "Centrifugal Pumps for Industrial Use in Petroleum, Petrochemical, and Natural Gas"
**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:**
Example: **APS200-420**
- **APS:** Single-stage, double-suction, split-case centrifugal pump designed according to API 610 standard
- **200:** Outlet diameter (in mm)
- **420:** Impeller diameter (in mm)
**Technical Advantages:**
1. The pump is designed for a service life of over 20 years (excluding wearing parts), with continuous operation life exceeding 3 years.
2. When using a larger impeller or different hydraulic model, the pump head increases by more than 5% at rated driver speed.
3. The pump can operate continuously at 105% of the rated speed and can run at higher speeds for short periods under emergency conditions.
4. The pump features an NPSH safety margin to reduce cavitation damage, fluid return flow, and separation flow across all operating ranges.
5. The working flow range is between 70% to 120% of the impeller’s best efficiency point, while the rated flow point lies within 80% to 110% of that point.
**Maintenance-Friendly Design:**
The axial split case structure allows for easy maintenance and disassembly. The middle coupling section between the pump and motor makes it possible to replace seals and bearings without opening the pump casing. Additionally, internal pump components can be inspected without removing the piping or motor.
**Comprehensive Monitoring System:**
To ensure safe and efficient operation, the APS series pump can be equipped with optional monitoring systems based on user requirements. These include:
- Bearing temperature monitoring
- Vibration monitoring
- Leakage detection system
