The design of the mechanical seal consists mainly of two parts: a movable part and a fixed part. The fixed part is usually a ring that is fixed in the pump housing. The movable part is mounted on the shaft and is pressed against the fixed part by means of a spring.

Mechanical sealing is achieved using secondary seals (bellows, rubber rings) and a friction pair. When choosing a mechanical seal, it is important to choose the material of the secondary seals and friction pairs.

Seals with shaft size 0.97, 1, 1.375, 1.813, 1.875, 2, 3, 4.5, 10 mm, 11, 12 mm, 14 mm, 15 mm, 17, 21, 22 mm, 23, 26 mm, 27, 30 mm, 34, 35 mm, 42 mm, 48 mm, 50 mm, 53 mm, 55 mm, 57, 58 mm, 60 mm, 63 mm, 65 mm, 67, 68 mm, 72, 73, 74, 75 mm, 76, 80 mm, 85, 95, 110, 120, 190, 200, 242, 260, 270, 275, 300, 335, 385

Mechanical seals are available in a variety of sizes, including 0.97 or 1 or 1.375 or 1.813 or 1.875 or 2 or 3 or 4.5 or 10 mm or 11 or 12 mm or 14 mm or 15 mm or 17 or 21 or 22 mm or 23 or 26 mm or 27 or 30 mm or 34 or 35 mm or 42 mm or 48 mm or 50 mm or 53 mm or 55 mm or 57 or 58 mm or 60 mm or 63 mm or 65 mm or 67 or 68 mm or 72 or 73 or 74 or 75 mm or 76 or 80 mm or 85 or 95 or 110 or 120 or 190 or 200 or 242 or 260 or 270 or 275 or 300 or 335 or 385. Selecting the right size mechanical seal is important for optimal performance and reliability. A mechanical seal with the correct shaft size ensures an accurate and secure fit on the pump shaft, distributing pressure correctly and preventing leakage.

Mechanical seals specifically suited for pumps can make a significant difference in the performance and reliability of your system. Mechanical seals from brands such as Allweiler are designed to meet these challenges, providing a reliable and durable seal for pumps in a wide range of applications. Whether conveying chemicals, water, oil or other liquids, Allweiler mechanical seals are tested and proven to provide high performance under various conditions. Plus, these seals are easy to install and maintain, which means you can spend less time on maintenance and more time doing what you do best.

Mechanical seals are essential to the operation of rotating devices, such as pumps. When selecting the right mechanical seal for a specific pump, it is important to consider factors such as pressure, temperature, and speed. Type number NB 32-160/01 U3.1D is specifically designed for use in pumps and provides the necessary performance and specifications to prevent leakage and extend pump life.
