In the processing industry, all stirring units, pumps and gear motors are used to keep process materials in motion for the sake of production. In this case, lots of shafts seals placed at drive shafts protect liquids from getting leaked out of the equipment or contaminated with dirt and grease. But when the pressure gets too high, leaks are more likely to happen. So, a wave-shaped rotary seal and ACE SEAL KIT have been introduced into the market to overcome this problem and it has been a great success so far. This sort of seal supports the maximum level of pressure that is applied on the machine. It has a sine wave contact path that decreases friction and allows self-cleaning. As a result, the seal elongates operating life.
1. Why Make a Switch from the Shaft Seals
Shaft seals, which are often used in the processing business especially the food and beverage industry, come with a rotation-symmetrical seal lip. This contains a groove-like contact path. When a machine runs wet, it can displace the medium at the contact surface. As a result, the seal runs in a dry condition and causes higher temperature and friction. As the friction increases, the machine loses its efficiency. The rise of temperature is very much unfavorable for temperature-sensitive process media. In fact, the seal lip coming in proximity with high temperature at high rotational speed can cause leakage and even damage the equipment.
2.Benefits of Using Wave-shaped Seals
Considering the failure of rotational sealing lip design, the modern technologists have developed a wave-shaped NAK Oil Seal. The sinusoidal pattern, present in this sort of seals, support wet-running applications in various machines. While the shaft of the seal rotates, every point of the sealing lip coats a different place of shaft repeatedly and moistens it with the medium. This, as a result, lowers temperature rise and friction at the sealing place. Even the wave-like pattern of the contact path offers self-cleaning advantage. If any small dirt particle comes under the sealing lip, they are quickly removed from the contact area. It reduces the chance of tearing down and expands operating life of the equipment and the CASE SEAL KIT.
