  Do you know the most common issue in rotating machinery? It’s pressure instability. It starts with vibration, noise, and seal failures, and may look controllable. But pressure instability is often the result of mechanical component problems hidden inside the system. Whether it's an  Ebara pump , HVAC systems with an  Armstrong pump seal , or a  compressor control valve , it is essential to understand the root causes of pressure instability. This helps  to save time, money, and equipment life. In this guide, we will explore the most common causes of pressure instability and how to prevent them. Let’s begin.       1. Worn or Damaged Pump Sleeves A  pump sleeve  protects the pump shaft from wear caused by seals, corrosion, and abrasive fluids. When the sleeve becomes worn or scored, the shaft no longer runs true. How this causes pressure instability: ·          Shaft eccentricity caus...

  Shafts play a crucial role in fluid handling systems. All important components, such as pumps, compressors, mixers, and agitators, rely on a rotating shaft to move fluids. For successful operations, proper sealing is essential to prevent leakage, energy loss, and equipment failure.  This makes effective shaft sealing a safety, performance, and cost issue. If you are working with a  mechanical seal , a  pump seal , a  Grundfos seal , or a  dry gas seal , the quality of shaft sealing directly impacts how well your entire system performs. In this blog, we will discuss why shaft sealing is critical in modern fluid-handling systems.                      1. Shaft sealing prevents leakage and product loss Shaft sealings act as a wall that stops fluid from escaping along the rotating shaft. Even minor leakage can cause serious problems and affect the ent...
