HSH seals are built for extended reliability in high pressure, high speed and highly viscous services such as mainline crude oil pipeline pumps. HSH seals are balanced, flexible stator cartridge seals with drive mechanisms and seal face geometries engineered for high torque loads and long-term performance. The HSH seal is fully compliant with API 682 Type A requirements.
A single balanced seal designed to mount outside the seal chamber. No wetted metal parts (RA-C) reduce seal costs for highly corrosive services, especially on non-metallic pumps. Installs easily on the outside of the seal chamber and is suitable for metallic and nonmetallic equipment such as plastic, glass, and lined designs.
A simple, proven and rugged design with dependability that has made it a favorite choice of maintenance personnel to seal ANSI chemical pumps. Heavy cross sections of the rotary components resist high levels of corrosion. Utilizing a simple rugged open rotary unit design, aggressive, abrasive and viscous fluids can be sealed easier than with other ANSI seal types that incorporate shrouded spring rotaries.
UC Series seals are balanced pusher seals with a substantial single coil spring that provides exceptional performance in the most demanding services including refineries, pipelines, and petrochemical services. UC seals are fully compliant with API 682, Type A requirements.
D Series seals are based on the UC Series, and add a pumping ring built into the rotating seal face body that establishes an exclusive Plan 23 cooling chamber around the seal faces. D Series seals excel in high temperature boiler feed water and hot hydrocarbon services.
