Desalination and brackish water pumps work under harsh conditions—high salinity, abrasive particles, and constant pressure.
Reliable sealing is critical to prevent leaks, maintain efficiency, and reduce downtime.
حلقات ختم كربيد التنغستن are widely used in these systems because of their durability, مقاومة التآكل, and long service life.
This article explains their advantages, applications, and best practices for decision-makers.
Why Desalination and Brackish Water Pumps Need Strong Seals
Prevent leaks → Protects expensive equipment and prevents contamination.
Maintain pump efficiency → Reliable seals reduce friction and energy waste.
Handle high salinity → Saltwater is corrosive to weaker materials.
Reduce downtime → Avoid unplanned maintenance and expensive repairs.
Protect the environment → Prevents saline leaks that could harm ecosystems.
خصائص حلقات ختم كربيد التنغستن
Tungsten carbide is a composite of tungsten and carbon, bonded with cobalt or nickel. Its properties include:
أقصى صلابة → Resists wear from abrasive particles in seawater.
قوة ضغط عالية → Handles high pressures in desalination systems.
مقاومة التآكل → Protects against saltwater and brackish water corrosion.
الاستقرار الحراري → Performs well under temperature fluctuations.
عمر خدمة طويل → Reduces maintenance and replacement costs.
كربيد التنغستن المرتبط بالكوبالت مقابل كربيد التنغستن المرتبط بالنيكل
1) كربيد التنغستن المرتبط بالكوبالت
Offers higher صلابة for pumps exposed to vibration.
Used in systems where mechanical shock is a concern.
2) كربيد التنغستن المرتبط بالنيكل
أرقى مقاومة التآكل for high-salinity environments.
Best for coastal desalination plants and brackish water systems.
