Isomag’s advanced magnetic face technology delivers unparalleled performance. The lapped flat faces create a positive liquid tight seal preventing lubricant leakage and the ingress of contaminants in both static and dynamic conditions on horizontal and vertical equipment alike. By optimizing the magnetic energy loading, Isomag’s are capable of running at shaft speeds well above average (up to 15,000 feet per minute) providing the ability to effectively seal the bearing housings on a wide variety of applications
John Crane offers a comprehensive range of filtration products to significantly reduce contamination, increasing the efficiency of your operation. Our products are designed to work together in complex systems to ensure optimum filter performance. Patented filtration technologies provide filter elements that are able to remove liquids in addition to solids within a single unit. Our replacement elements incorporate John Crane's patented design features, ensuring maximum filter performance
Often your very method of production will introduce contamination to your process, whether from imperfect ingredients, necessary reagents or process equipment, and to deliver an end product free from impurity and contamination, inhibiting, filtering action is required. Filtration is typically an imperfect process - some fluid remains on the feed side of the filter and fluid and particulates become embedded in the filter media.
Do you want to minimize leakage from your pumps in an effective manner? This is a challenge operators and maintenance managers face on a daily basis, which can prove costly. John Crane offers a wide selection of packing materials in compression packing, automatic packing, floating packing, and injectable packing.
