Our Products
Mechanical Seals
The scope of our mechanical seal product range far exceeds that of any other seal manufacturer. John Crane has the right product for any application — from small elastomer bellows seals used in millions of domestic water pumps and double mechanical seals that ensure maximum sealing safety to large, highly customized dry-running gas seals for mission-critical, high-speed turbo compressors.
Seal Support Systems
The right seal support system is critical to promoting seal reliability and overall energy efficiency. John Crane customizes support systems to meet a variety of seal specifications, contributing to safe, cost-effective, reliable operations that reduce harmful environmental effects. Our support systems comply with constantly changing design codes and standards, equipping end users to meet increasingly stringent demands.
Seal Face Technologies
Our comprehensive suite of seal face technologies is 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. These innovations improve seal face lubrication to optimize the performance of rotating equipment in all process industries.
Power Transmission Couplings
For more than 50 years, John Crane’s flexible couplings have helped rotating equipment operate at optimum levels and with maximum availability. As a result, John Crane’s couplings have become the first choice of many of the world’s leading companies. Our policy of continuous innovation and product development ensures that we satisfy the changing demands of the market while fully complying with all relevant industry standards.
Bearing Isolators
Isomag’s advanced magnetic face technology delivers unparalleled performance. The lapped flat faces create a positive liquid-tight seal that prevents 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, Isomags are capable of running at shaft speeds well above average (up to 15,000 feet per minute), effectively sealing the bearing housings on a wide variety of applications.
Equipment Filtration
John Crane offers a comprehensive range of filtration products to significantly reduce contamination and increase 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 remove both liquids and solids within a single unit. Our replacement elements incorporate John Crane's patented design features, ensuring maximum filter performance.
Process Filtration
Your method of production often introduces contamination into your process, whether from imperfect ingredients, necessary reagents or process equipment. Delivering an end product free from impurity and contamination requires inhibiting filtering action.
Packing
Do you want to minimize leakage from your pumps in an effective manner? Operators and maintenance managers face this costly challenge on a daily basis. John Crane offers a wide selection of compression packing, automatic packing, floating packing and injectable packing materials. Learn more about our packing, which is equipped to handle the vast majority of sealing solutions across nearly all applications.
