• Precision Lapping: The ceramic face is lapped to within 2 light bands of flatness, ensuring a tight seal with the carbon rotary face immediately upon startup.

• Bonded or Booted: Available in both bonded cup and O-ring mounted seat configurations to match the specific Roten housing style (L1k or L4 dimensions).

• Monolithic Design: We use solid (monolithic) SiC faces rather than inserted rings, providing superior heat dissipation and mechanical strength.

• Chemical Inertness: SiC offers broad chemical resistance, allowing standard water pumps to be repurposed for light chemical transfer duties when paired with FKM bellows.

• Fatigue Resistance: We use a high-density welding process for the bellow leaflets, increasing fatigue strength against the vibration and pressure pulsations of boiler feed pumps.

• Exact Dimensional Match: Replicates the working length (L1k) of the Roten original for a drop-in fit.

• Shaft Protection: The rubber bellow covers the shaft completely in the seal area, protecting it from corrosion and eliminating fretting wear.

• Robust Spring: Uses a sturdy single coil spring that resists clogging in wastewater applications better than multi-spring designs.

• High-Torque Drive: We use premium elastomer bellows that provide strong torque transmission to the TC face, ensuring it doesn't slip under load.

• Solid Face Construction: Unlike some competitors who use thin inserted faces, our TC faces are solid or securely shrink-fitted for maximum durability.

• Unitized Mini-Seal: The spring, bellow, and drive ring are integrated into a single unit, preventing parts loss during repair.

• Soft Face Seating: The carbon face conforms quickly to the mating seat, ensuring a tight seal almost immediately after installation.

• Chemical Inertness: The switch to a PTFE wedge allows standard Roten-style seals to operate in fluids that would destroy NBR or EPDM rubber.

• Short Working Length: Designed to fit shallow stuffing boxes without modification to the reactor flange.
