It is essential if all boats and other marine machines can be careful while on the sea or oceans to ensure that water does not get into their boat engines, especially where the water has corrosive contents. However, the crafts using stuffing boxes or conventional parking glands on the propeller shaft exit have been continuously experiencing a water drip, so they need to lubricate them regularly. Most people do not like the idea of lubricating the surfaces after every few days, and thus, to avoid this, you can consider using the PYI shaft seals from the PYI Inc.
A dripless marine shaft seal uses two primary seals to attain a dry bilge: face seals or lip seals. The lip seal has its inside made from a rubber sleeve and a metal housing fixed in the shaft where it rotates. However, it has one main disadvantage: it quickly causes tears and wears to itself and the shaft.
PYI shaft seals manufactured by PYI Inc uses the face seal instead of the lip seal, where a supported rubber bellow tool is attached to a carbon graphite flange on one side while the shaft log is attached to the other side. The bellow forces the flange against the polished steel rotor, mounted to the shaft rotating over the flange. Water is not allowed to pass through the rotating surfaces because they are high polished, even when the engine produces the highest vibrations.
People who have tried the PYI shaft seals have come back explaining how better and more beneficial the seals are than the previous stuffing boxes. Among the reasons why boat owners love it is that you can set it and forget about it because it is free from maintenance as it does this by itself. The nitrile O-rings put between the rotor and the shaft are responsible for this. Nitrile is a long-lasting material that resists even the highest vibrations and temperature, unlike rubber which is easily damaged by high vibrations and temperature.
A significant percentage of boat operators have agreed that the PYI shaft seals are better than the stuffing boxes. They are durable in that they can be used for over six years without any complaints or water getting into the craft. Moreover, there is no shaft wear, maintenance, or adjustments. Propeller Depot is an industry leader when it comes to supplying PYI marine shaft seals across the World.
