We just discovered that one of the seals on our pumping system is leaking. Do you have any ideas as to what could have caused this, and can you offer some advice for selecting a good seal?
Modern engine concepts, like higher engine speeds and oil temperatures, longer intervals between oil changes and lubricants with modern additives, require new solutions for dynamic seals. They have to withstand the high loads lastingly. PTFE technology is the answer, since it perfectly meets these demands.
Overall, hard rubber gaskets are an indispensable component in various industrial applications. Their durability, flexibility, compression resistance, and chemical resistance make them a reliable choice for sealing solutions. Whether used in pipelines, machinery, engines, or automotive equipment, hard rubber gaskets play a crucial role in ensuring the efficiency and safety of operations. With their long-lasting performance and versatile properties, it is no wonder that hard rubber gaskets are a preferred choice for sealing applications worldwide.Most effective sealing is obtained with optimum shaft surface finishes. The sealing efficiency is affected by the direction of the finish tool marks and the spiral lead. Best sealing results are obtained with polished or ground shafts with concentric (no spiral lead) finish marks. If you must use shafts with spiral finish leads, they should lead toward the fluid when the shaft rotates.
Some disadvantages of NBR are poor ozone, sunlight and weather resistance as well as limited high temperature and flame resistance. For higher temperature resistance, a much better material to use is Silicone.

The aerospace sector also heavily relies on rubber edge gaskets for sealing aircraft components, such as fuel tanks, air conditioning systems, and hydraulic linesDoes it mean the seal stops the leakage completely? Well, on the practical grounds yes because there is no ‘visible leakage’.
In conclusion, PU oil seals are a testament to the power of material innovation in solving engineering challenges. Their superior properties, resistance to harsh environments, and adaptability make them a go-to choice for engineers seeking reliable sealing solutions. As technology continues to evolve, we can expect further advancements in the design and application of PU oil seals, contributing to increased efficiency and reliability in industrial operations.Mark the position of the rotor arm by lightly scratching a line on the distributor body.
