I’ve been in the millwright business for many years. In all that time, I never heard anyone blame a dial indicator for not getting repeatable alignment results. But I have […]
Why do we need to align a coupling in the first place? If you ask the mechanic, maintenance manager, reliability technician, or plant engineer, you might get four different answers! […]
Explosive decompression (ED), also referred to as rapid gas decompression (RGD), is a failure mechanism of elastomer seals which is due to the rapid decompression of gaseous media. When elastomer seals are exposed […]
You hear about it everywhere – design optimization. The world requires more and more efficient and reduced emissions products, as with the U.S. Environmental Protection Agency Engine Testing Regulations and European Commission Ecodesign […]
Concerns regarding the amount of energy that is consumed – and potentially wasted – by industrial facilities in the United States officially reached the highest levels of the federal government on Aug. 30, […]
Pump engineers have a wide range of sealing options available to them which cater for the diversity of pump applications. In designing pumps and other associated equipment like compressors and […]
Precision Polymer Engineering (PPE) is pleased to present technical data on measuring the Sour Gas resistance of their range of high performance EnDura and Perlast elastomers.
Most centrifugal pumps today have mechanical seals. However, those pump that still use packing glands instead of mechanical seals require frequent maintenance and are more likely to show up in […]
Aggressive pumping environments can be problematic for pump engineers. On the one hand it’s impossible to design the pump to be resistant to every kind of chemical, while on the […]
On rotating machinery, runout is defined as the degree to which a shaft or coupling deviates from true circular rotation. Every shaft or coupling has a center or rotation, or […]
When it comes to expensive rotating machinery, there is often a need to identify a problem before it occurs, as catastrophic failures are often orders of magnitude more costly than […]
