How to Choose EN853?

Understanding EN853 Specifications

When it comes to hydraulic hoses, understanding the European Standard EN853 is crucial for ensuring the right application and performance. EN853 specifically focuses on the specification for wire-reinforced hydraulic hoses and outlines different types based on their construction and performance characteristics. Here’s how to choose the right EN853 hose for your application:

1. Identify the Application Requirements

Before selecting an EN853 hose, it is essential to understand the specific requirements of your application:

• Fluid Types: Identify the fluids that the hose will be conveying. Different fluids may require different hose materials.
• Operating Pressure: Determine the maximum pressure the hose will be subjected to during operation.
• Temperature Range: Check the temperature limits of both the fluid and the environment where the hose will be installed.
• Flexibility Needs: Consider how much flexibility is needed for installation and operation.

2. Determine Hose Construction Types

EN853 hoses come in various constructions. Familiarize yourself with the different types:

• EN853 1SN: Single wire reinforced hose suitable for medium-pressure applications.
• EN853 2SN: Double wire reinforced hose designed for high-pressure applications, providing greater strength and flexibility.
• EN853 1ST: A single layer textile reinforcement hose, typically used for low-pressure applications.
• EN853 2ST: Double layer textile reinforcement hose, ideal for low to medium-pressure applications.

3. Assess the Hose Diameter

The diameter of the hose affects both the flow rate and the overall efficiency of your hydraulic system. Here are important factors to consider:

• Nominal Bore: Check the nominal diameter required for your system to ensure proper flow and pressure maintenance.
• Compatibility: Ensure that the hose diameter is compatible with existing fittings and connectors.
• Space Constraints: Measure available space for installation; a larger diameter may not fit in confined areas.

4. Review the Manufacturer’s Specifications

Different manufacturers might provide hoses that slightly vary in quality and performance. Make sure to:

• Check Certifications: Ensure the hose complies with EN853 standards and any other relevant certifications.
• Evaluate Material Quality: Consider hoses made from high-quality materials for better durability and operational life.
• Look at Testing Information: Manufacturers should provide testing info regarding pressure and temperature performances.

5. Seek Expert Advice

If you’re unsure which EN853 hose is suitable for your application, seeking expert advice can save you time and costs:

• Consult with Professionals: Speak to hydraulic specialists or engineers for tailored recommendations.
• Utilize Vendor Services: Many suppliers offer technical services to help select the right hose.
• Ask for Revisions: If your system changes or upgrades, ask for revised recommendations to maintain performance.

By following these steps, you will be well-equipped to choose the right EN853 hose for your hydraulic application.
