HY6000 Injected Sealant is a putty-like product made from fibers and sealant. As an advanced sealing technology with superior performance, it has been widely adopted in mining, metallurgy, petrochemical, fertilizer, power generation, papermaking, and wastewater treatment industries. It is the ideal replacement for traditional packing and mechanical seals.

Today, energy conservation, environmental protection, and innovation-driven development are global priorities and critical challenges for all businesses.

Water is essential in daily life and industrial processes, giving rise to a wide variety of pumps. Pump sealing is a critical concern for both manufacturers and users, as experience has shown that leakage issues are far more complex than they appear.

Water leaks from pump seals can reduce the lifespan of the pump and other components. Leaked water entering the bearing housing along the shaft can contaminate the bearing lubricant and oil film, causing premature bearing failure. Data shows that even 0.002% moisture in the lubricant can shorten bearing life by 48%, and 51% of motor failures are caused by bearing failure.

Issues with traditional packing used as shaft seals for 1 pumps

1.1 packing in direct contact with the shaft or sleeve can cause wear, so the sleeve must be replaced on a scheduled or as-needed basis.

1.2 Lubrication cooling packing rubs against the shaft or sleeve. The packing seal requires a certain amount of leakage that is difficult to control.

Friction between the 1.3 packing and the shaft or sleeve reduces motor shaft power and consumes electricity. Data shows that power loss can reach an alarming 5%-10% in some cases.

Replacing the packing on 1.4 requires stopping the pump, which disrupts continuous production.

1.5Due to the wide variety of packing specifications, inventory levels are high, making spare parts management difficult.

Issues with mechanical seal at the pump shaft end for 2

Replacing 2.1 requires disassembling the pump, which not only creates significant work but also reduces the precision of the equipment and other components, thereby shortening the overall service life.

The presence of 2.2 water scale and solid particles can damage sealing surfaces and clog springs.

Most mechanical seals for 2.3 require flush or cooling water, which increases the number of potential leak points.

2.4 installation requires a certain level of technical expertise; otherwise, it may affect performance.

3 Injection Pump Seal Packing, Online Repair Technology

3.1 supports online maintenance without downtime, saving time and effort while reducing repair costs.

3.2 has a low coefficient of friction and does not wear the shaft or bushing.

3.3 saves energy, reduces consumption, protects the environment, and lowers packing inventory.

4: Initial Installation and Ongoing Maintenance

4.1 Remove the packing or mechanical seal from the original pump, install a valve at the flushing water port, keep the valve closed, and retain it for future maintenance.

Clean the pump shaft or sleeve, and install 1 gaskets on both the inner and outer sides of the packing chamber. Then add the packing material.

4.3 allows refilling packing during operation without shutdown. When packing wear or seal leakage occurs, connect a hydraulic gun to the reserved valve port, open the valve, and inject a small amount of fresh packing until leakage stops.
