As a result of this design principle the seal can be run with a very small operation gap. Self-adjusting of the seal rings during operation is guaranteed. The seal's gas consumption is 5 to 10 times less than that of rigid labyrinth units. The Espey WDKS-Eco is designed for dry running and requires no additional lubrication. The shaft seal seals radially to the smooth and cylindrical machine shaft. As a further advantage there are no sealing components mounted on the shaft and hence no additional shaft vibrations will be caused.<br/>\nThe service intervals of Espey WDKS-Eco are 3 to 4 years. These units represent a reliable sealing solution, even when put to tough use.<br/>\nThe radial split housing guarantees quick assembly and disassembly, also in case of seal ring maintenance, without having to dismantle the machine. The individual seal components are easy to handle and are not subjected to any extreme risk of breakage. The housing is equipped standardly with a gas port for connecting up either buffer gas supply or a vacuum extraction line, depending on the mounting arrangement.<br/>\nAlternatively, the gas port can be used to create a grease buffer.<br/>\nThe contact-less running seal rings raise no additional friction and hence no additional power consumption of the machine.", u'ApplicationMedia': '<ul class="SGBulletList">\n<li>(Solids containing) 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<br/>\nTension spring / detent: 1.4571', u'ProductVariant': 'None', u'ProductName': 'Espey WDKS-Eco', u'ArticleNumber': '', u'SupplyForm': '', u'IDSealDrawing': '', u'PageHeader': 'Espey WDKS-Eco', u'DescriptionList': '<ul class="SGBulletList">\n<li>Easy installation by split housing design (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>'}
