Refrigeration Compression Components
John Crane compressor seals and metal bellows seals, among others, are designed to meet the demands of today’s refrigerants and prevent leakage in accordance with stringent industry standards. We have a wide range of products specific to the refrigeration industry, including:
Type 285: Gas-lubricated, non-contacting single seal for cryogenic pumps
Elastomer Bellows Seals
Type 2: Multi-purpose, non-pusher elastomer bellows seal available in single, double and balanced arrangements
Seal Support Systems
GR1/1C: General duty reservoir that can withstand pressure up to 16.3 bar while providing buffer/barrier fluid to a dual-seal arrangement
GR2/2C: General duty reservoir that can withstand pressure up to 30 bar while providing buffer/barrier fluid to a dual-seal arrangement
GR3/3C: General duty reservoir that can withstand pressure up to 73 bar (stainless steel) or 62 bar (carbon steel) while providing buffer/barrier fluid to a dual-seal arrangement
GP-S/GP-D: Non-API gas control panel for filtering, regulating and monitoring gas supply to gas-lubricated pump seals
Cyclone Separators: Typically used in an API Plan 31 arrangement and incorporated in the seal flush line (API Plan 11 ) from the discharge of the pump
Safeunit™ Ultima: Specially designed to control seal water flow and pressure in extreme conditions
Safeclean: Removes impurities and particles, providing clean seal water for stuffing boxes and mechanical seals
Fixed Geometry Thrust Bearings: Offers extreme running precision and stability; energy-efficient under low to medium loads
