Description
Tungsten Carbide Check Ring
Product Overview

Tungsten Carbide Check Ring (also known as anti-backflow ring) is manufactured from high-performance tungsten carbide-cobalt (WC-Co) material. It features extremely high hardness, excellent wear resistance, corrosion resistance, and impact resistance. This product is widely used in high-pressure plunger pumps, hydraulic systems, injection molding machines, oilfield equipment, and other applications requiring unidirectional flow control, effectively preventing medium backflow and ensuring stable system operation.

Key Features
  • Ultra-high hardness: HRA 89-92, significantly better than conventional alloy steels or ceramics.
  • Wear & corrosion resistant: Suitable for particle-containing media, acidic/alkaline liquids, and high-temperature & high-pressure environments.
  • Precision fit: End faces and sealing surfaces can be mirror-lapped to ensure reliable sealing.
  • High fatigue resistance: Long-term use under high-frequency pulsating pressure without cracking or deformation.
  • Extended service life: 3-5 times longer than conventional metal check rings.
Typical Applications
  • Valve assemblies of high-pressure plunger pumps
  • Fluid ends of fracturing pumps in oilfields
  • Chemical metering pumps
  • High-pressure cleaning equipment
  • Hydraulic impact tools
