Hydrowype D-Series Rod Scrapers

 

The D-Series wiper line including the Style-DS and accompanying Style-DP elastomeric wiper, is intended for use primarily where the following conditions are to be encountered:

  • direct contact of the wiper with ultra-heated or molten materials
  • severely adhered contaminants (baked into or fused with the rod surface)
  • significant shock loading and side-loadings
  • existing rod damage, where a tool-steel grade wiper is required to scrape off deflected (dislodged) rod material
 
Heavy duty snap non-constrained floating scraper design in a range of base metals including stainless steel and copper alloys and with optional titanium nitride coating.

In the first part we have the standard urethane wiper in the wiper groove of the glad to another cylinder. The contamination easily goes right past the wiper and seal, contaminating the cylinder. In the second part we have placed a Gadjets Hydrowype D-Series scraper on the outside of the glad so you can see exactly what is happening.

By customer request we melted a plastic garbage bag on the rod and used the Gadjets Hydrowype D-series to remove it. We tried many times to just use the torch to melt the bag onto the rod, but could never achieve adherence. We learned that we had to get the rod hot enough to melt the bag.
