Piping

Second of Three Parts

I received a lot of feedback on my column “How Much Energy Do Pipes Remove?” in the September issue of Pumps & Systems. This column described the use of two computer programs that evaluate the...

Different material and design combinations offer application-specific advantages.

Piping plans for mechanical seals are used to improve the environmental conditions around a seal, extend its capabilities and allow operators to monitor seal performance. American Petroleum Institute...

Previous articles in this series explained how oversized piping systems can have higher operating and maintenance costs. Higher maintenance costs can adversely affect the reliability and uptime of...

Last of Two Parts In Part One of this series (Pumps & Systems, February 2014), the operating and maintenance costs for pumped systems were isolated. The next steps are to set realistic goals for...

Because pump systems can be complex, determining the root cause of problems in an operating system can often lead to a hit-and-miss approach that is time consuming and costly. For six years, that was...

Harrington Industrial Plastics announced the acquisition of ProTec Construction Services & Supply.“Harrington’s commitment to excellence and growth has never been stronger, which is why...

Main oil pump hydraulic geometry was the root cause of numerous false turbine/generator overspeed trips.Troubleshooting rotating equipment failures and improving reliability is a process of...

Determining which pumps and their associated systems to assess is the first step in the process.First of Two PartsWhat Is a Pump Assessment?A pump assessment is a mini performance test of the pump...

Pumps & Systems, May 2008In trench-type wet wells, the pump intakes are placed near the bottom of a deep, narrow trench coaxial with the inlet pipe but considerably below it (see Figure 1). The...

 With continuously increasing energy costs, pump manufacturers must provide energy efficient solutions for fluid transfer. Besides hydraulically optimizing current technology, manufacturers are...

 Pumps & Systems, March 2008Soils with high concentrations of clay and silt can wreak havoc on construction sites, drain pipes, sewers and pumps. Users working with soils might want to...

Pumps & Systems, June 2007 Last month, we discussed applications of low head axial flow pumps ("Field Testing: Theory vs. Reality," Pumping Prescriptions, May 2007). Knowing your system...
