Products
Mechanical Seals
Mechanical seals are critical components used to prevent leakage between a rotating shaft and stationary parts in equipment such as pumps, compressors, and agitators. By creating a secure seal, they play a vital role in industries such as Oil and Gas, Chemical Processing, Clean Water Management, and Pharmaceuticals, where reliability, efficiency, and environmental protection are paramount.
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 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. Available for different seal types, dependent on the unique challenges faced by the application, John Crane delivers the right face technology for the right application.
