Chemical Application Products
Specialized applications such as aggressive acids, dewatering chemicals and high-pressure, high-speed polymerizing fluids require extensive materials research and proven designs. John Crane products are specifically developed to meet the unique needs of customers in the chemical processing industry:
Non-Contacting Seals
Type 2800EX Cartridge Seal: Capable of handling up to 20% by volume solid in suspension
Type 2800 Series: Polymerization-mitigating seal that eliminates frictional heat and reduces emissions by up to 92%
Metal Bellows Seals
Type 670 Metal Bellows: Extremely durable in aggressive environments
Type 680 Metal Bellows: Provide corrosion resistance in low-temperature applications
GL1B Metal Bellows: Made with Inconel 625 for strength and corrosion resistance
Type 609 Metal Bellows with Grafoil: Heat transfer-specific; ideal for pumps with limited seal chamber clearance
Type 2609 Dual Metal Bellows and Grafoil Cartridge Seal: Provides superior seal face stability at elevated temperatures
Slurry Seals
Type 5860 Slurry Seal: Heavy duty for the harshest abrasive slurry environments
O-ring Pusher Seals
Type 48SC: Provides emissions compliance with reduced cost of ownership
Type 5600 Cartridge Seal: Modular design that allows unmatched versatility and reduced inventory
Vessel and Agitator Seals
Type 32 Mixer and Agitator Seals: Cleaning-in-place or sterilization-in-place (CIP/SIP) seal; excellent for operation in vacuum conditions
Seal Support Systems
WCH/WCV/K2S: Water-cooled heat exchangers for use where water is readily available
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
Power Transmission Couplings
A Series: Urethane element couplings known for quick installation without moving prime mover or driven equipment
L Series: Designed for demanding industrial applications with a scalloped hub for the shaft
H Series: High-performance couplings designed for unspared machines
TSKS/TSCS: Designed to give the most flexible solution for high-torque and misalignment conditions. Ideally suited to meet the pumping, motor, and turbine drive power transmission needs of the chemical industries.
Packing
Style C1065: Chemlon Graphite Fiber, ideal for controlled leakage and extrusion resistance at high pressures and shaft speeds
Style 387I: A special high-temperature/pressure and corrosion-inhibited valve stem packing
Style 1625G: High-temperature graphite braided packing that offers dimensional stability, reduced process contamination and ease of use
Style 1335: Cost-effective, general-service packing constructed of the highest-quality synthetic fibers and lubricants
Style 1340: Cost-effective, general-service graphited packing designed to handle a wide range of fluids at moderate to high temperatures, pressures and shaft speeds
Style CVU/CVH: Automatic packings containing no lubricants or dispersions, well suited for non-contaminating services
MLS Series: Cartridge seals designed for rotary positive displacement pumps handling high-viscosity fluids
Filtration Systems
Liquid Filtration: Filters designed for almost any liquid application, from lubrication, hydraulic or bearing oil systems to water injection systems
Seal Gas Filtration: Removes liquid and particle contamination to allow continuous supply of clean, dry gas
Fuel-Gas-Filtration: Individually tailored for maximum reliability, regardless of the condition of the supply gas
Fuel Oil Filtration: Patented elements that remove water and particle contamination for maximum reliability
Double 3-way and 6-way Transfer Valves: Provides continuous operation while one side receives maintenance
Filter Elements: Patented design for maximum performance and running time between change outs
John Crane’s Seebach Filtration Systems, Elements and Customized Filtration Solutions are used in the chemical industry for processing reagents, such as separating impurities or undissolved substances from solutions, and for processing reaction mixtures.
