High Pressure Double-Pass Split Design Rotary Joint Cast Iron Housing with Positive Spherical Seal

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • High-Pressure Fluid Transfer: Designed for rotating systems to transfer fluids (e.g., oil, water, gas) under high-pressure conditions, ensuring seamless operation in dynamic environments.
  • Dual-Pass Rotary Functionality: The double-pass split design enables simultaneous bidirectional fluid flow (e.g., in/out) in rotating machinery, enhancing efficiency in industrial and commercial applications.

Key features

  • 1. Corrosion-Resistant Material Composition

    • With a cast iron and carbon steel body reinforced by zinc plating, you can ensure long-lasting durability in corrosive environments. ~30% more corrosion-resistant than uncoated alternatives.*

  • 2. Advanced Double-Pass Split Design & Spherical Seal

    • With the Double-Pass Split Design and Positive Spherical Seal, you can achieve seamless rotation and leak-proof performance in high-pressure systems. Reduces maintenance needs compared to standard rotary joints with flat seals.*

  • 3. High-Pressure Tolerance

    • With a cast iron housing engineered for high-pressure applications, you can operate reliably in demanding industrial systems. Supports pressures exceeding 200 bar, outperforming conventional low-pressure rotary joints.*

  • 4. Versatile Mounting & Integration

    • With threaded ends and multiple mounting points, you can easily integrate this component into pumps, pipelines, or machinery. Compatible with ~50% more system configurations than non-modular rotary joints.*

  • 5. Industrial-Grade Compliance

    • With materials and construction meeting ISO industrial safety standards (e.g., corrosion resistance, pressure ratings), you can ensure compliance with global manufacturing regulations. Verified by third-party testing for commercial use.*

Product details

High Pressure Double-Pass Split Design Rotary Joint Cast Iron Housing with Positive Spherical Seal

Supplier's note

  1. Technical Breakthroughs:

    • The positive spherical seal reduces friction by 20% compared to flat seals, extending service life.
    • The split design cuts installation time by 40% versus traditional rotary joints.
    • Cast iron housing provides 30% higher pressure tolerance than aluminum alternatives.

  2. Version Selection Guide:

    • Base Model: Ideal for standard industrial pumps and low-rotation systems (e.g., HVAC).
    • Advanced Model: Recommended for heavy machinery with moderate pressure fluctuations (e.g., construction equipment).
    • Pro Model: Best for high-pressure applications like oil drilling or aerospace, where durability and rotational speed are critical.

    Example: The Pro version’s 6500 PSI rating exceeds industry benchmarks by 30%, enabling safe use in deep-sea drilling systems. Paired with its zinc-plated surface, it withstands saltwater corrosion while maintaining precision rotation.
