Soft-face Mechanical Shaft Seals

Soft-face Mechanical Shaft Seals

Soft-face mechanical shaft seals utilize relatively soft, malleable face materials for components that rotate with the shaft. They are typically in full contact against a fixed opposing seal face orientated perpendicular to the shaft. This differs from how traditional, hard-face, mechanical seals operate where fluid film or boundary lubrication is needed, as is commonly found on centrifugal or lobe pumps, where Soft-face mechanical shaft seals are not used.
