Espey shaft sealing systems work with moving beared floating seal rings. These segmented seal rings largely are made of carbon and adapt radially to shaft movements. As a result they enable a very small and extremely uniform sealing gap, which is reflected in correspondingly low leakage rates.<br/>\nThe split housing guarantees a simple and speedy installation and deinstallation. The seal can be fitted directly at the sealing point without necessitating and disassembly of machine components such as bearing and drive unit. Preferred applications for Espey WD200 are those in which process gases to the atmosphere or processes to the atmosphere have to be prevented.<br/>\nThe hardness of the carbon seal rings often makes it necessary for the shaft to be given a hard coating or to employ a hard-coated shaft sleeve to counter premature wear. In applications involving condensate formation shaft or shaft sleeve should additionally be fitted with a splash rim to enable directed throwing off to the outside of the housing.', u'ApplicationMedia': '<ul class="SGBulletList">\n<li>Gases</li>\n<li>Fumes and exhaust,solids containing, flammable (Atex), acid containing and toxic gases</li>\n<li>(Solids containing) steams / liquid mist</li>\n<li>Oil mist / penetrating oil</li>\n<li>Water</li>\n</ul>', u'MaterialCombination': 'Seal ring: Carbon, PTFE compound<br/>\nHousing: 1.4021, 1.4571, Hastelloy\xc2\xae, Titanium, Inconel\xc2\xae, others<br/>\nTension spring / detent: 1.4571, Hastelloy\xc2\xae, Titanium, Inconel\xc2\xae', u'ProductVariant': 'None', u'ProductName': 'Espey WD200', u'ArticleNumber': '', u'SupplyForm': '', u'IDSealDrawing': '', u'PageHeader': 'Espey WD200', u'DescriptionList': '<ul class="SGBulletList">\n<li>Easy installation by split housing design<br/>(shaft removal not required)</li>\n<li>Long-term operation time</li>\n<li>Maintainability</li>\n<li>Segmented seal rings for easy replacement</li>\n</ul>'}
