Water Pumps
Shaft sealing for clean water, river water and general industrial water pumps.
Natural ramie fiber gland packing for pumps, valves, marine equipment and low-pressure water service. Available with optional tallow, PTFE or silicone impregnation for different operating requirements.
Natural ramie fiber packing with different braid styles and impregnation options for water, marine and general industrial sealing applications.
Ramie gland packing is a braided compression packing made from natural ramie fiber. It is commonly selected for water pumps, marine equipment, irrigation systems, low-pressure valves and general utility applications.
Ramie fiber provides good water absorption and conformability. Depending on the application, the packing can be supplied with tallow, PTFE or silicone treatment to improve lubrication and sealing performance.
We supply ramie packing for overseas distributors, pump manufacturers, marine equipment suppliers, maintenance companies and industrial buyers, with custom sizes, braid styles and packing rings available.
Ramie packing is particularly suitable when economical sealing, water compatibility and natural fiber content are important selection factors.
Manufactured from natural ramie fiber, providing a renewable material option for suitable industrial sealing applications.
Ramie fiber naturally absorbs water and can swell to improve contact with the sealing surface.
The flexible fiber construction can provide relatively low shaft wear in appropriate water-service applications.
A cost-effective option for low-pressure water, marine and general utility sealing applications.
Tallow, PTFE, silicone oil and other treatment options can be selected according to application needs.
Suitable for distributors, OEM manufacturers, marine suppliers and industrial maintenance buyers.
Performance depends on fiber construction, braid style, lubricant treatment and actual operating conditions. Confirm the final specification before ordering.
