Model 20 / High Pressure – For use in most high pressure applications. Pressure-balanced design withstands high pressure while maintaining low face contact pressure. Model 20 Magseals can be manufactured for shafts up to 5 inches in diameter. Consult factory for information.
Note: Magseals cannot be ordered by size alone. Even in standard configurations materials must be matched to the fluids involved. Please contact our Engineering Department at the earliest practical time during your project, and we will design a seal with materials and features suited to your operating conditions.
