High water-based gland packing material for seawater pump

 Gland Packing Material Data Sheet 

It mainly operates in harsh media such as water, oil, weak acids, alkalis, and salts.

Gland packing material for seawater pump applications is engineered using a high-water-content formulation that provides exceptional lubricating ability and thermal stability in marine environments. The water-based composition significantly lowers friction at the shaft interface, preventing excessive heat buildup and ensuring smooth operation even during prolonged pumping cycles. Unlike traditional fiber or grease-impregnated packings, this high-water-content structure minimizes crystallization, prevents hardening, and maintains consistent compression under fluctuating loads. Its resistance to chloride-induced corrosion makes it especially suitable for seawater, brackish water, and other saline fluid systems where conventional packings often degrade.

The packing adapts well to shaft movement, forming a controlled leakage film that protects both the packing and the shaft sleeve. This controlled moisture layer also reduces wear, extending service intervals and lowering the overall cost of maintaining seawater pump equipment. Widely used in marine circulation pumps, ballast systems, coastal desalination plants, seawater cooling pumps, and offshore water transfer units, this high-water-content gland packing material delivers stable performance in environments where salt exposure, constant rotation, and temperature variations challenge conventional sealing materials.
