When You Don’t Trust Your Alignment Tool

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?

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 Resistance of Seals and O-rings

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 […]

Q&A on 3D Inverse Design: Pump Efficiency through Optimization

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 […]

Wilden – Shifting Your Perception of AODD Pumps for Energy Efficiency

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, […]

Effective Sealing For Pumps With Elastomers

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 […]

Measuring Sour Gas Resistance

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.

Tips For Improving Performance of Pump Packing

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 […]

Types of Fluoroelastomers Seals for Pump Users: Explained

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 […]

VibrAlign – Coupling or Shaft Runout

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 […]

Industrial Vibration Monitoring

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 […]
