HiPerLip^® - Elevating Equipment Performance with Rotary Shaft Seals

In numerous industrial applications, maintaining the integrity and performance of equipment in challenging environments is paramount. If your machinery operates in high-dust, potentially corrosive atmospheres that demand reliable and long-lasting sealing solutions, HiPerLip^®, also known as rotary shaft seals, is your ultimate answer. Parjet’s HiPerLip^® offers advanced sealing technologies designed to deliver exceptional performance, even under adverse conditions.

At the core of HiPerLip^®'s advantage is the integration of innovative features such as dual sealing lips, wiper designs, and specialized materials engineered to combat the harsh realities of industrial environments. The flexibility of these seals is vital, as they can accommodate a variety of challenges from temperature extremes to high pressures, ensuring operational efficiency remains uncompromised.

Advantages of Metal Casing

The incorporation of a metal casing with HiPerLip^® enhances their performance and durability. The metal casing not only provides structural integrity but also assists in maintaining optimal sealing performance in challenging environments. It is particularly useful for applications involving high lateral loads, as it helps stabilize the rotary seal against potentially damaging forces. For industries that demand reliability, such as automotive, aerospace, and manufacturing, utilizing HiPerLip^® can drastically improve operational efficiency.

Wiper Design for Enhanced Protection

One of the standout features of HiPerLip^® is the optional wiper design. If your equipment is frequently exposed to high levels of dust and particulates, implementing a seal with a wiper will significantly enhance its protective performance. The wiper acts as a barrier, preventing contaminants from entering the sealing zone, thus reducing the risk of wear and tear on the primary lip. This is particularly crucial in applications involving hydraulic motors or oil components, where maintaining low leakage is essential.

For instance, consider the Dual primary lips seal with special design on metal backup washer (with wiper). This design focuses on low leakage systems and is particularly suitable for hydraulic applications where the risk of fluid contamination is high. The wiper not only assists in keeping the sealing area clean but also enhances the longevity of the seal, allowing your equipment to maintain peak performance for extended periods, even in high-dust environments.

Adaptability to Diverse Conditions

In various machinery sectors, adaptability is critical. The Primary lip energized with spring and wiper configuration is another exemplary feature worth noting. This design option is specifically tailored for scenarios where the shaft's roundness may be inconsistent or when the operational environment presents challenges such as vibration and misalignment.

The energizing spring applies consistent pressure on the sealing lip against the shaft, maximizing the seal's effectivity even in less-than-ideal conditions. This not only mitigates leakage but also safeguards against wear that is often exacerbated by harsh external factors. With the inclusion of the wiper in this design, it ensures that dust and debris are consistently kept at bay, thus preserving the integrity of the sealing interface.

Robust Material Properties

HiPerLip^® ’s sealing lip is formulated from advanced PTFE (Teflon) compounds that inherently possess impressive low friction characteristics. This contributes to a significant reduction in heat generation during operation, preventing oil carbonization and enhancing the overall durability of the sealing solution. Compared to traditional rubber seals, HiPerLip^® exhibits a coefficient of friction that is three times lower, marking a considerable improvement in performance, especially after prolonged periods of inactivity.

Moreover, HiPerLip^® is designed to operate efficiently under a wide range of pressures and speeds. HiPerLip can manage speeds up to 10.2 m/s (2000 fpm) at pressures of 35 bar (250 psi), and even up to 30 m/s (6000 fpm) in low-pressure applications. This incredible versatility makes it an ideal choice for dynamic environments where operational conditions can change rapidly yet necessitate consistent sealing performance.

Chemical Resistance and Temperature Tolerance

In addition to their mechanical advantages, HiPerLip^® exhibits exceptional resistance to a variety of corrosive media. They are compatible with environments where the PH lies between 4 and 12.5, remaining steadfast even under extreme temperatures and pressures. Should your applications involve exposure to highly corrosive substances, opting for seals with a metal casing crafted from erosion-resistant materials, such as high nickel alloys like Hastelloy^®, could provide the added protection needed.

Furthermore, the temperature tolerance of HiPerLip^® is remarkable, serviceable in environments reaching as high as 200°C (392°F) without risk of deformation or failure. The seal continues to perform efficiently even in extreme cold, down to -40°C (-40°F). This resilience in temperature fluctuations makes HiPerLip ® an invaluable choice for applications in sectors like aerospace, automotive, and heavy machinery where thermal conditions can vary dramatically.
