Navigating the Department of Energy (DOE) Energy Conservation Standard and Test Procedure for Pumps
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
As the compliance date of January 27, 2020 approaches, the complexity of the US DOE Energy Conservation Standard (ECS) and Test Procedure (TP) for Pumps leaves many pump manufacturers, distributors, engineering procurement ...
Precision Grouting of Critical Rotating Equipment
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Recently, there has been a trend in the way new equipment is being mounted that affects precision grouting during installation. Improper grouting not only wastes material, but can result in misalignment, unnecessary ...
Protective Wisdom: HF Releases and Associated Pumps
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Catastrophic releases of hydrofluoric acid from pumps in Alkylation Units are a matter of public record. Exposure to HF can be fatal and specific safety measures are needed to enter the unit. Therefore, the reliability of ...
Fundamentals of MV Drives
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Medium voltage ASDs (MV Adjustable Speed Drives) and motors are widely applied to plant rotating machinery like compressors, pumps, fans, extruders, mills, kilns, etc., ranging from a few horsepower (HP) to tens of thousands ...

Midstream Pipeline Applications – Design Aspects and Considerations for Mechanical Seals
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
There are few applications that place a significant demand on mechanical seals such as those associated with the handling of various fluids through pipelines. Pipeline applications are unique in that they typically encompass ...
Water Hammer and Piping Stresses
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This tutorial provides guidance to help understand the causes, and to prevent or mitigate the effects of water hammer, or fluid transients, in piping and pipeline systems. The text of this paper is based on early drafts ...
The Theory and Application of True Weighted Efficiency -- A New Metric to Evaluate Pump Energy Efficiency Considering Multiple Operating Conditions
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Energy efficiency is being emphasized more prominently in the pump industry. A consistent method for evaluating pump energy efficiency with multiple operating conditions is needed. New energy efficiency indices have been ...
Best Practices for Cartridge Mechanical Seal Installations
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
The reliability of a mechanical seal depends on more than the design of the seal itself. It also depends heavily on the practices used to install the mechanical seal into the centrifugal pump or other equipment. The actual ...
