CR819 vs CR819S Common Rail Injector Pump Test Bench: Detailed Comparison and Upgrades

When selecting a professional Common Rail Injector Pump Test Bench, customers often ask about the difference between the classic CR819 and the upgraded CR819S. While both machines share excellent functionality and the same sleek appearance, the CR819S is designed for heavy-duty performance with specific hardware enhancements.

1. Size and Dimensions

The most visible difference is the physical footprint. The CR819S is significantly larger, with dimensions of 201*121*194cm. This larger chassis allows for better internal airflow, easier maintenance access, and a more robust presence in your workshop compared to the standard CR819.

2. Six Key Hardware Upgrades in CR819S

The CR819S incorporates six specific improvements designed to increase durability and testing precision:

• Cooling System: Adopts a larger industrial fan for superior heat dissipation during long testing cycles.
• High-Pressure Pump: Equipped with a brand new CP3 pump ensures stable rail pressure generation.
• Injector Mounting: Uses an improved, heavy-duty injector holder for faster and more secure clamping.
• Instrumentation: Features a higher quality pressure gauge for precise mechanical readings.
• Power Management: Includes an upgraded power distributor for electrical stability.
• Pressure Control: Added pressure regulating valve (DRV) for finer control over the fuel system.

3. Shared Technical Functions

Both the CR819 and CR819S deliver the comprehensive testing capabilities Beacon is known for:

• Standard Functions: Testing common rail pumps (Bosch, Denso, Delphi, Siemens), Piezo injectors, and Denso HP0 pump function. Includes Injector Coding.
• Optional Functions: EUI/EUP testing (with cam box), HEUI testing (CAT C7/C9, C3126), CAT 320D pump testing, and VP37/VP44 pump testing options.
• Power: Available in 11kW, 15kW, 18.5kW, and 22kW motor options.
• Control: Precise pressure control from 0-2400bar.

Whether you choose the standard CR819 or the enhanced CR819S, you are getting a top-tier diagnostic tool. However, for workshops requiring extended operation times and maximum component durability, the CR819S is the recommended choice.
