Mechanical Seal Style 59A
API Heavy Duty Rotating Multi-Spring Single Cartridge Seal
For API 682 Applications
The Flexaseal Style 59A is designed specifically to conform to API 682 Category 2 Applications for Midstream and Downstream Oil and Gas Applications. Standard design features include:
- Oversized Monolithic Seal Faces for superior heat dissipation and durability.
- Circumferential Flush System to evenly distribute cooling flush flow around the seal faces.
- Convertible Outboard Bushing for fixed, floating and segmented designs to allow for all types of secondary leakage capture.
- Tang Drive System for reliable face torque transfer and reduced O-Ring hang up.
- Heavy Duty Springs to mitigate process debris clogging and reduce spring quantity.
The 59A is also available with contacting and noncontacting secondary sealing. The Flexaseal FC seal (Available as 59A/FC) provides decades of proven operational reliability as a contacting secondary seal. The Flexaseal FGSA (Available as 59A/FGSA) is our newest lift-off design for API applications that require a noncontacting secondary seal.
