Wipers
Wipers
For dirt and contaminants exclusion
The primary function of a wiper is to keep contaminants such as dirt, dust and moisture from entering the fluid power system.
Contaminants can cause significant damage to the rod, cylinder wall, seals, valves and other components. One of the primary causes of premature seal and component failure in a fluid power system is contamination. It should be noted that rod seal failure is normally a swift result of wiper failure. Particular attention should be drawn to the selection of the wiper, and the following should be taken into consideration:
Wiper Design Considerations:
• Groove Geometry…
• Lip Geometry…
• Working Environment…
Our Wipers are classified as follows:
– Highly-Contaminated Environment Wipers & Scrapers
– Dust and Particle Exclusion Wipers
– Dry Rod Operation Wipers
– Low-Friction System Wipers
Highly Contaminated Environment Wipers & Scrapers
Typical Application
For heavy dirt, mud and moisture exclusion or equipment that is exposed to all-weather conditions, including applications with a vertical or upward orientated rod of the cylinder.
Operating Range
Surface Speed: up to 13ft/s (4m/s)* depending on wiper type and material
Temperature: -40°F to 400°F (-40°C to 200°C)* depending on seal material
Materials: high-performance polyurethanes, PTFE, PTFE, engineered thermoplastics, NBR, Nitrile, FKM, Viton®, H-NBR, EPDM, FDA-compliant food grades, low- and high-temperature grades, including proprietary Duralast™, Duraloy™, and Permachem™ compounds.
