In order to understand centrifugal pump leakage, it’s important to first understand the basic operation of a centrifugal pump. As the flow enters through...

Figure 1: Dual unpressurized seal with API plan 76 This article addresses the normal and excessive leakage rates of mechanical seals in main pipeline pumps...

By John Calder, Dura Pump Mechanical seals prevent pumps from leaking by containing the pressure of the pumping process and withstanding the friction caused by...

One of the pumps I am handling in my current project is an OH2 self-venting centrifugal pump. It is designed for a capacity of...

The support bearings of literally millions of machines are located at or near the ends of the shafts so supported. However, design, configuration constraints...

The plumbing profession is all about trust—using tried and true methods that have stood the test of time to ensure that pipe connections will...

Although fulfilling the original design intent and functioning as intended, many “traditional” sealing systems found in industrial applications waste considerable amounts of energy. The uncontrolled...

Mechanical seals can fail for many reasons, and vacuum applications present particular challenges. For example, certain seal faces exposed to vacuum can become starved...

Energy Management is critical to operational efficiency. Reviewing energy use in each link of the supply chain of a business can produce significant benefits....

With the discoveries of large new natural gas deposits, including shale formations, competition is intensifying for LNG supply contracts, making it imperative that LNG...
