While it is obviously a better decision to keep water out of your boat than let it in, the majority of engines built today use a system of dripping to allow seawater into the engine and cool the components. This seawater corrodes or contaminates many parts of the engine, meaning the choice between overheating and slow destruction of an engine presented a lose-lose scenario to boat owners. Pss dripless shaft seals remedy this problem by using a fitting to cover the passage to the interior of the engine. This brand is the most well-used in today's marine market. Many of the best boat construction companies and shipping yards utilize this simple seal, and it has been certified by numerous different companies that construct nautical machinery.
Whether you own a boat, rent a boat, or plan to start a nautical hobby, you should know about what a pss dripless shaft sealer can do for a boat's engine. A seal can take out the process of repair, adjustment, and price that comes into packing type gland units that allow small quantities of water to enter into the engine. The standard rate of one drip per minute may seem entirely harmless, especially since the heat of the engine keeps the moisture from accumulating, but the chemicals and saline within the water do far more to harm an engine than the water itself. Using pss dripless shaft seal technology to eliminate this water completely -- the seal makes the unit entirely water tight -- helps to keep the propeller shaft from further wear and tear. What's more, the unit can be retrofitted in order to accommodate shafts that vary from twenty to one hundred fifty millimeters.
The seal itself sits between a steel rotor and a carbon flange. While the rotor turns, the flange does not, and a seal is needed to prevent movement from harming either part. The rotor works to exert force on the bellows and the pss dripless shaft seal compensates for the constant movement. Instead of requiring fluid to cool it, the polish of the gears keeps water from passing through and reduces the friction that causes more heat. Attaching a stainless steel collar to the shaft keeps the rotor, the shaft, and the rings itself from wear and tear during a motor's shelf life. Indeed, many owners report that this dripless seal can keep moisture out of their boat years after it has been installed.
