Hydraulic seals are critical components in fluid-power systems, preventing leaks and contamination while maintaining pressure in cylinders and machinery. Proper hydraulic seals classification and material selection are essential for system reliability. Seals can be classified by their function, by the direction of pressure they handle, and by whether they operate dynamically or statically Types of Hydraulic Seals 1. Function classification: Common seal types include rod seals (which prevent...

Hydraulic seals and oil seals are both important parts that stop fluids from leaking out of machines. They may look the same, but they are made for different reasons and are used for different things. This article explores hydraulic seals vs oil seals in terms of structure, materials, performance, and industrial applications, as well as how to choose the right one for your machinery.  Key Differences Between Hydraulic Seals and Oil Seals Primary Function:  Oil seals keep lubricants in and...

The Role of Well Packing in Hydraulic Fracturing Hydraulic fracturing, or pressure pumping, is a well stimulation method used to extract oil and gas from tight formations such as shale and sandstone. In this process, a high-pressure pump—commonly known as a fracturing pump—injects a slurry mixture of water, chemicals, and proppants (sand or ceramics) into the reservoir to create fractures that release hydrocarbons. At the heart of the pump’s fluid end, which handles this high-pressure slurry,...

Nordson® hot melt and fluid dispensing systems, such as the popular ProBlue® series, are widely used in packaging, labeling, and product assembly. However, like all precision equipment, their performance heavily depends on the integrity of internal seals. A failed seal can lead to downtime, product contamination, and costly repairs. In this article, we’ll cover the top 5 seal failures in Nordson® systems, what causes them, and most importantly, how to prevent them with proper maintenance and...

Introduction The mining industry operates in one of the most demanding environments on earth—exposure to abrasive dust, high pressure, shock loads, and extreme temperatures is the norm.

Common Machine Failures Often Caused by Bad Seals If you’ve ever faced these issues:Glue leakage or dripping at the glue pot Inconsistent band feed or trimming Pressure drops or air leaks Melting chamber overheating Reduced machine precision over timeYou might blame the glue, the operator, or even the machine brand. But the real issue? Worn-out or chemically incompatible seals and O-rings. Seals in edge banders operate under harsh conditions: high temperature, hot-melt adhesives, rotating...

Skeleton oil seals, also known as skeleton seals or seal skeleton structures, are essential components in rotating equipment. These seals play a critical role in preventing oil leakage and blocking external contaminants, ensuring the stable operation of machinery across a wide range of industries. What Is a Skeleton Oil Seal?A skeleton oil seal is a rotary shaft seal composed of two main parts: a flexible sealing lip (usually rubber-based) and an embedded metal skeleton. The skeleton of the...
