APV® (SPX®) MECHANICAL SEALS

HWS

  • Single or Flushed Seals
  • Suits Rosista W Range
  • Outphased APV® W Pumps

HWS (single) and HWS-F (flushed) are designed to replace the mechanical seals fitted to outphased APV® W or "World" Series centrifugal pumps. Based on Rosista's "W" range prior to acquisition. Not to be confused with newer, W+ range.

 

HWS & HWS-F share the same inboard o-ring mounted rotary, driven by a legged spring. The HWS stationary is of a monolithic block-type designed to be clamped-in with additional sealing gaskets.

  • Flushed Seal

The HWS-F stationary is double-sided, allowing for an additional external cyclam seal (H) with port hole allowing running of a lubricating fluid.
