Among marine shaft seals, no other type sells better across the world than PSS shaft seals.  These marine mechanical seals are even included by default by many of the world’s finest boatyards, whose expert craftsmen consider them to be standard equipment.  PSS stands for “Packless Sealing System,” which is an excellent description of the technology that makes these seals so exceptional.  These marine shaft seals function without as much constant attention as other kinds of sealing systems.  In particular, PSS marine shaft seals do not need to be adjusted often and they free boating enthusiasts from the need for frequent maintenance.

In addition, a PSS Shaft Seal is completely watertight, which means that water will not accumulate in the bilge.  This feature also helps to cut down on wear and tear to the shaft of the propeller so that boating enthusiasts can enjoy a trouble-free watercraft experience for a long while to come.

PSS Shaft Seals are simple to install, even in retrofit situations, and can fit shafts as small as ¾ inch and as large as six full inches or 150 mm across.  In essence, the PSS marine shaft seal consists of a face seal between the two flat surfaces provided by a carbon flange, which remains stationary, and a rotor, which rotates.  The shaft seal serves to compensate as the propeller produces thrust.  This helps to eliminate not just problems caused by vibration, but also those that are a result of small misalignments.  A key part of these seals is the use of O-rings that rotate along with the shaft so that they will not wear down over time.
