John Crane customizes support systems to meet a variety of seal specifications, contributing to safe, cost-effective, reliable operation and reducing harmful environmental effects. Our support systems comply with constantly changing design codes and standards, and meet the increasingly stringent demands on end users. Learn more SEAL FACE TECHNOLOGIES Our comprehensive suite of seal face technologies are designed to overcome rigorous sealing challenges, including limited seal face lubrication and severe-service duties that adversely affect reliability, operational costs and seal life. Designed by our engineering experts, John Crane’s face treatment options help your equipment power through low-lubricity and dry-running conditions by using advanced micromachined patterns and features to improve seal face lubrication to optimize the performance of rotating equipment in all process industries Learn more POWER TRANSMISSION COUPLINGS John Crane’s flexible couplings have provided a rugged and reliable service to the industry for over 50 years, helping rotating equipment operate at optimum levels and providing maximum availability. As a result, John Crane couplings have become the first choice of many of the world’s leading companies. John Crane’s policy of constant innovation and product development ensures that we continue to satisfy the changing demands of the market while fully complying with all relevant industry standards. Learn more BEARING ISOLATORS 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 Learn more EQUIPMENT FILTRATION 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 Learn more PROCESS FILTRATION 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. Learn more PACKING 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.
