CAPI™ Type A, B and C Category I Single and Dual Seals

CAPI™ Type A, B and C Category I Single and Dual Seals

• Employs Qualification Tested API 692 Technology
• Thin cross-section (TXS) seal designs for mature asset installation including API 610, 5th Ed. with a 0.500″ (12mm) radial cross-sectional space between the shaft and seal chamber
• Robust and reliable seal face drive (Patented floating drive technology) reduces high stress points at equipment start-up
• Probably the most compact single and dual API cartridge seals on the market which employ API 682 technology
• All sizes available from 1.000″ to 5.000″ (24mm – 125mm)

CAPI™ Type A Category II and III Single and Dual Seals

• Qualification Tested to API 682
• Stationary flexible element offered as standard for improved pusher design performance as outlined in API 682 Section 6.1.1.5.
• Rotary design is available on request
• Multi-port Flush design offered as standard for optimum seal face cooling
• World-leading bi-directional pumping ring performance with 0.062” (1.5mm) radial clearance between rotor and stator; conforming with API 682 Section 8.6.2.3 without compromise
• All sizes available from 0.750” to 4.375” (20mm – 110mm)

CAPI Type B Category II and III Single and Dual Seals

• Qualification Tested to API 682
• Effective seal-face heat dissipation achieved by a directed barrier fluid flow path, irrespective of shaft rotational direction
• Multi-port Flush design offered as standard for optimum seal face cooling
• 12 edge-welded bellows convolutions as standard
• All sizes available from 0.750” to 4.375” (20mm – 110mm)

CAPI™ Type C Single and Dual Seals
