Set Up of Plan 52 Reservoirs Seal Pots

Piping Plan 52 Set Up (Graphics Courtesy of Hydraulic Institute, www.pumps.org) Dual mechanical seal with reservoirs can be used with good effect in implementing Plan 52 to provide buffer fluid resulting in no direct leakage of process fluid to the atmosphere. Circulation between the reservoir and outer seal is maintained by tangential flow porting [...]

Silicon Carbide vs. Tungsten Carbide Hard Sealing Surfaces

How Silicon Carbide Outperforms Tungsten Carbide Silicon Carbide out performs Tungsten carbide as hard faces in most seal applications. It's tribological properties allows for lower coefficient of friction and longer life. In heavy slurry or other extreme pumping conditions the properties are enhanced when you match silicon carbide with a silicon carbide impregnated with [...]

Why Use A Flush Port

Why Use a Flush Port? It may seem like common sense, however, many users simply plug the port Most applications (ANSI pumps), a line from discharge to seal flush provides circulation to cool seal and flush solids away from the seal. For dirty applications, use a clean liquid flush from an outside source. This [...]
