• California Residents: PROPOSITION 65 WARNING
• Seal faces are installed using a patented heat shrink process ensuring correct, distortion-free face alignment at all recommended temperatures.
• The springs are located in the stationary body of the seal in the seal water (barrier fluid). The seal water washes the springs, preventing process chemical corrosion and reduces the risk of the springs becoming clogged. Shaft misalignment does not vibrate or wear out the O-rings.
• PTFE slot rings replace the traditional O-rings in places where they are exposed to the product, preventing sticking.
• Protected faces, the seal face carriers are driven by machined fits, preventing metal stress from distorting the face.
• Patented double-balanced design allows the use of both pressurized and unpressurized seal water (barrier/buffer fluid) and prevents face overload.
• SB2 series seals will accept ± 0.080"/± 2.0mm axial movement (shaft end play) during normal operation due to their piston design. Impeller adjustments do not affect face stress or spring strength.
