Using Split Seals for Leak Free Turbine Shaft Sealing

Sealing devices for Kaplan and Francis hydropower turbines are critical components that assure reliable operation and environmental compliance. Those working with these turbines in the hydropower industry are discovering that using mechanical split seals for main shaft sealing can make significant advances in their operations. In today’s post, we interview John Sousa, a Chesterton expert […]

Fugitive Emissions: Understanding API Standards for Valves & Packing


Since the introduction of the U.S. Clean Air Act in 1963, the U.S. Environmental Protection Agency (EPA) and individual states have set increasingly stringent consent decrees for fugitive emissions from industrial facilities. Many companies have implemented Leak Detection and Repair (LDAR) programs, and industry groups have focuses efforts on helping member companies decrease valve emissions.  Most recently, […]




Pump Sealing Basics: Mechanical Seals vs. Packing


Mechanical seals vs. packing? Which is the best and most effective sealing technology for your pump or agitator application? Long ago, companies didn’t want to switch to mechanical seals because of the complicated installation and need to completely disassemble the equipment.  The invention of cartridge and split mechanical seals effectively eliminated those dilemmas, but many operations have […]




Stepping Up Your Chain Lubrication Program for Best Performance


Chains are the workhorses of many industrial production processes. But as important as chains are in the day-to-day functions of many plant operations, chain lubrication and maintenance is often an afterthought. The reality is that internal chain wear (especially in the popular metal-pin-and-bushing chain type) can put a real kink in production up-time if not […]




5 Key Features of Good Mechanical Seal Design


Mechanical seals come in a wide variety of designs. These designs differ in the way they are driven, the choice of secondary seals, and the location of the springs. Mechanical seals have all been designed to meet certain criteria in terms of application, cost, fit, ease of installation, and capability to seal. There are, however, a […]




Mechanical Seals & Equipment Conditions—Basic Rules


Does the condition of the equipment affect the life and performance of the mechanical seal? The answer is yes. Equipment conditions play a very important part in determining overall seal life and reliability. Typically: Mechanical seals are installed onto a rotating shaft and designed to prevent visual leakage Two highly polished, spring-loaded “seal faces” come in […]




The Basics of Industrial Lubricant Selection


There are several factors to consider when selecting the right industrial lubricant. A manufacturer’s recommendation is a great starting point, but it doesn’t have to be the only option. Most manuals are written for ideal conditions, but these guidelines don’t address the real environment in which the equipment is being used. What if your equipment manufacturer […]
