Dynamic Seal
On some tough pumping services like paper stock and slurries, mechanical seals require outside flush and constant, costly attention. Even then, seal failures are common, resulting in downtime. We offer a Dynamic Seal which, simply by fitting a repeller between the stuffing box and impeller, eliminates the need for a mechanical seal.

BENEFITS OF DYNAMIC SEAL:

  • External seal water not required.
  • Elimination of pumpage contamination and product dilution
  • Reduces utility cost
  • No need to treat seal water
  • Eliminates problems associated with piping from a remote source
HOW IT WORKS

At start-up, the repeller functions like an impeller, and pumps liquid and solids from the stuffing box. When pump is shut down, packing (illustrated) or other type of secondary seal prevents pumpage from leaking.
