The necessity of shaft seal water flow switches

Packing and mechanical seals used in fluid applications, which both require constant cooling and lubrication. Clean and reliable gland seal water supply is a critical utility in any oil sands mining facility. Pressurized gland water is pumped into the seals of slurry pumps in order to keep them clear of bitumen, sand and fines. This gland seal water serves three important functions: enables the pump shaft to rotate within its sleeve with minimum friction, prevents the slurry from back-flowing into the seals and damaging the shaft, and allows for a small amount of cooling of the pump shaft, which heats up as it rotates at high speeds.

The most important factor in designing a gland seal water system is to ensure the system is reliable and has sufficient pressure. If gland water pressure is too low, it will not be able to overcome back-pressure from the pump and cause the slurry to back-flow into the sleeve. So, a Gland Seal Water Flow Switch will be a necessary part of the seal water system.

If user ask for a shaft seal flow switch, we always recommend the below products:
