Contact SupplierThe John Crane Type 2100 is a robust, unitized elastomer-bellows mechanical seal engineered for demanding fluid-handling applications.
At the heart of its design is a non-clogging, single-coil spring that maintains face loading under all operating conditions. The innovative bellows is pressure-supported, preventing collapse or folding at high pressures.
A positive drive mechanism using interlocking tangs ensures the rotary face tracks accurately with the shaft, avoiding slippage during system upsets.
The Type 2100 excels in centrifugal, rotary, and turbine pumps, as well as compressors, chillers, and similar rotating equipment.It is widely used in water-based processes—water treatment, HVAC systems, potable water, wastewater, pool/spa services, and general industrial fluid ’s also suitable for pulp/paper, food processing, and marine systems.
