Mechanical Seal Style HPPD
High-Pressure Face-To-Face Dual Stationary Multi-Spring Cartridge Seal
For high-pressure process duties and zero-emission requirements
The Style HPPD seal is designed for exceptional reliability in demanding applications, such as high-pressure, highspeed, and hazardous services. This seal style addresses the challenges of sealing high-pressure process fluids in refinery, pipeline, and power generation industries where zero-emissions are required.
- Versatile across industries: ideal for oil and gas, petrochemical, and power generation.
- Adaptable to process needs: the configurable Arrangement 3 platform can be designed for use with a pressurized API Plan 54 system or a suitable API Plan 53 when equipped with our high-performance pumping ring.
- High torque, high speed: engineered for extreme torque loads and rapid surface speeds, perfect for high-energy pumps where zero emissions are required.
Typical Flush Plans: 54/53B/53C

The Flexaseal Style HPPD provides superior design flexibility with highly adaptable features to meet specific application needs and comes standard with:
- High duty seal face materials
- Premier siliconized carbon/graphite, FlexSiCG, primary ring combines self-lubricating capabilities of carbon/graphite with the rigidity and wear resistance of silicon carbide.
- Reaction bonded silicon carbide mating rings improve lubricity at the interface.
- Laser-etched lubrication-enhancing features on the mating ring amplify film load support and reduce face-generated heat.
- Robust seal rings with FEA-optimized geometry nearly eliminates seal face deformation.
- Unique mating ring key-drive mechanism evenly distributes drive forces, reducing fracture potential.
- Stationary design allows for high-peripheral speeds.
- Metal-to-metal torque transfer to flexible stationary element eliminates wear-induced seal hang-up.
- Metal oxide coated dynamic O-ring surfaces prevent wear from fretting and ensures smooth long-term operation.
- Separate inboard and outboard mating rings improve safety over designs with a common mating ring by isolating inboard and outboard seals.
- Expansive barrier fluid cavity for thermal management in high pressure applications.
Tailored Solutions with Customizable Features for Enhanced Reliability
- Radial or axial pumping ring for barrier fluid circulation without an external pump
