USED John Crane 1-09878

The John Crane / Flowserve / Ingersoll 1-09878 Type 1 Mechanical Seal is a general-purpose elastomer bellows shaft seal designed to prevent leakage in rotating equipment such as pumps and compressors. This Type 1 style seal is widely regarded as an industry-standard “workhorse” due to its versatility, durability, and ability to handle a broad range of fluids including water, chemicals, and light slurries. It operates by creating a tight sealing interface between the rotating shaft and stationary housing, minimizing leakage while maintaining smooth shaft rotation.
Engineered with a flexible elastomer bellows and single-spring design, this seal automatically compensates for shaft misalignment, wear, and vibration, helping extend equipment life and reduce maintenance. Mechanical seals like this are critical components in industrial systems, as they protect equipment, improve efficiency, and prevent fluid loss in applications such as process pumps, mixers, compressors, and agitators across industries like chemical processing, water treatment, power generation, and manufacturing.
