Wipers and Scrapers
Protecting Systems by Reducing Contamination
- Used in reciprocating and rotary applications
- Prevent contamination and premature system failure
- Protect rod seals from environmental contamination
- High wear resistance materials ensure long service life
Typical Healthcare & Medical Applications:
Wipers and scrapers are most commonly found in cylinder or rotary applications. When used in conjunction with a rod seal they can extend the service life of your life sciences equipment. Typical applications are prosthetic knees, patient lifts, hospital beds, surgical drills and other powered hand tools.
Materials Specific to Healthcare & Medical
Our Medical wipers and scrapers come in a wide variety of materials including metals, elastomers, Turcon® and Zurcon®. Many of these compounds are compliant with FDA CFR177.2600, 3-A, USP Class VI, Cytotoxicity (USP 87), NSF, KTW, WRAS etc.
About Wipers and Scrapers
Wipers and scrapers are used in a variety of medical, pharmaceutical and biotechnology applications, generally in reciprocating cylinder or rotary applications. Their seal lips are designed to scrape foreign particles or moisture from the piston rod, thus preventing contamination of the media being sealed. In doing so, the wipers or scrapers extend the service life of the other sealing and bearing components in the device.
Both single- and double-acting designs of wipers and scraper are available. Not intended to seal pressure on their own, they work in conjunction with a rod seal to achieve the optimum sealing configuration for an application.
