Hydrowype M-Series Rod Scrapers
Hydrowype M-Series wipers are intended for use in applications where a wide range of containment particle sizes are anticipated and where gland space is ample.
This is a relatively wide and deep profile which incorporates a rubber or polymer "Seat" that under compression, holds the scraping elements in place behind a rigid lip or keeper ring (such as a retaining ring).
Slits extending from the ID of the scraping elements permit the inner copper alloy Scraping Elements to flex to accommodate rod diameter variations and ovality and to allow the transmission of scraping load to the rod by permitting an interference fit.
A secondary (usually polymer) wiper and encapsulating "can" are available as options. Hydrowype M-Series Scrapers are available to address high or low heat environments. In these models, the default Nitrile elements are replaced with Viton or Teflon for the Seat and secondary Wiper and provide resilience through a wide temperature range to allow the wiper to perform without the non-metal elements "relaxing."
An all-metal version is also available on request.
