This PTFE-graphite centrifugal pump gland packing is engineered for stable sealing inside the centrifugal pump gland, combining the chemical resistance of PTFE with the thermal conductivity of graphite. Its low-friction performance supports continuous shaft rotation while maintaining controlled leakage and long service life in demanding pump applications.

Hebei Xinda provides precision-engineered centrifugal pump gland packing designed to meet the rigorous demands of rotating shaft systems. Unlike static seals, a centrifugal pump gland requires packing that can handle continuous friction, high surface speeds, and thermal expansion while maintaining a controlled leakage for lubrication and cooling. As a leading gland packing manufacturer, we offer customized sealing solution.

Q1: How much leakage is normal for a centrifugal pump gland?
A: A small amount of leakage (approx. 8-10 drops per minute) is essential for cooling and lubricating the centrifugal pump gland packing. Over-tightening can cause excessive heat and damage the pump shaft.
Q2: Which material is best for high-speed centrifugal pump shafts?
A: For high-speed applications, we recommend Carbon or Graphite-filled PTFE. These materials have superior heat dissipation compared to pure PTFE, preventing the packing from hardening or glazing.
