NBR&PU Rubber Valve Insert O-Ring Seal Gasket for Valve and Piston of Mud Pump

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • High-Pressure Sealing: Designed to provide airtight and fluid-tight seals for mud pumps, preventing leakage in high-pressure environments such as oil drilling and industrial machinery.
  • Durability Under Stress: Made from NBR (nitrile rubber) and PU (polyurethane) compounds, ensuring resistance to abrasion, chemicals, and extreme temperatures for long-term performance in demanding applications.

Key features

  • 1. Material Technology

    • With a NBR (Nitrile) & PU (Polyurethane) composite material, this O-ring ensures superior resistance to oil, chemicals, and abrasive mud. The dual-material design provides ~30% greater durability than standard rubber seals*, making it ideal for harsh oil field environments.

  • 2. Interactive Design

    • With a reinforced outer lip design, the O-ring guarantees secure installation and alignment in valve and piston systems. This precision-engineered shape reduces displacement risk by 25% compared to generic O-rings*, minimizing leaks under high-pressure conditions.

  • 3. Performance Parameters

    • With a pressure rating of up to 5000 PSI, this seal outperforms traditional rubber gaskets rated at 3000 PSI*, ensuring reliable performance in high-stress mud pump operations. Its flexibility maintains seals even in fluctuating temperature ranges.

  • 4. Scenario Solutions

    • Designed specifically for mud pump applications, this O-ring effectively handles abrasive slurry and high-pressure flows. It reduces downtime by preventing leaks and wear in oil field drilling and pumping systems, unlike general-purpose seals.

  • 5. Certification Standards

    • Complies with API (American Petroleum Institute) standards and ISO material safety certifications, ensuring industrial-grade reliability and chemical resistance. This meets rigorous requirements for oil field equipment performance and safety.

Supplier's note

  1. Technical Breakthroughs:

    • Material Blend: The NBR-PU hybrid improves abrasion resistance by 30% compared to standard NBR seals.
    • Tighter Tolerances: ±0.1mm precision reduces leakage risks in high-vibration mud pump environments.
    • Extreme Temp Range: The Pro Model’s -40°C to +150°C capability outperforms industry benchmarks by 20%.

  2. Version Selection Guide:

    • Base Model: Ideal for standard mud pumps with moderate pressure (≤150 bar) and ambient temperatures.
    • Advanced Model: Recommended for oil fields with acidic mud or high-pressure drilling (up to 200 bar).
    • Pro Model: Best for extreme Arctic/Arctic operations or ultra-high-pressure fracturing systems.

With the Pro Model’s 250 bar pressure tolerance, operators can safely handle hydraulic fracturing without seal failure. Pair its expanded temperature range with PU’s abrasion resistance to extend pump maintenance intervals by 40%.
