How it works
A stainless rotor on the shaft spins against a stationary carbon flange. Bellows preload keeps the precision-lapped faces in constant contact, creating the seal and accommodating minor movement, misalignment, and vibration.

Suits shaft sizes ~20 mm to 150 mm (3/4"–6-1/2")
Ovlov Marine can measure, specify, and supply ancillaries (vent/bleed lines, hose, clamps, spares)
