Common Causes of O-Ring Leakage and Key Installation Considerations
O-rings are one of the most common sealing solutions in pumps, especially those made from rubber. Their simple shape makes them easy to manufacture, cost-effective, and widely applicable. Regardless of the overall size of an O-ring, its cross-sectional diameter is typically just a few millimeters, making it lightweight and material-efficient. O-rings are easy to use, install, and replace, and they are known for their excellent sealing performance in a wide range of applications. O-rings are versatile enough to be used in both static and dynamic seals. In static seals, they can withstand pressures exceeding 100 MPa, while in dynamic applications, they can handle up to 30 MPa. They are suitable for a broad temperature range of -60°C to 200°C, making them effective for sealing against various media. As a result, O-rings are increasingly used in pump designs. How O-Rings Work in Sealing O-rings are typically installed between a groove and the sealing surface. A certain amount of compressi
