In the October 2008 issue, we evaluated efficiency and energy savings for a typical centrifugal pump ("Efficiency, Energy and Life Cycle Cost"). Many said the Energy Estimator helps when dealing with...
 Solution to Pump Challenge #2: Moving a Pump from the Bottom of a Dry Pit
In the August 2009 issue, we considered the following challenge: From the available data tables, the vapor pressure of 150 deg F water is about 4 psia, or (x 2.31) = 9 psia.Initially, when the...
In the foothills of the Andes, among the sprawling vineyards of picturesque Mendoza, Argentina, stands an innocuous equipment cabinet located by the side of an infrequently used mountain pass. The...
Dynamic sealing technology has continued to advance in recent years, changing from off-the-shelf radial lip seal commodities to high-tech engineered products. As asset uptime and governmental...
An OEM and an end user had installed a number of large, double-suction pumps for a water pumping station project (Figure 1). Soon after, they began to suspect that the pumps were a significant...
High Temperature Electric Submersible Pumps Effective in Oil Sands Production
Some oil and gas industry analysts have estimated that heavy oil and bitumen represent more than two-thirds of the world's oil reserves. As global energy demands increase, demand for production from...
This month's Sealing Sense was contributed by FSA Members Marty Rogin and Jim Richter The March 2009 Sealing Sense concluded that pipe strain can cause failure of the packing or mechanical seal since...
In the demanding conditions of the oil and gas industry, plant managers are realizing that lubrication best practices can help improve equipment reliability, optimize maintenance and reduce energy...
Understanding technology capabilities and application requirements is important when selecting a wireless technology for an application. The reasons to choose wireless include reduced installation...
Suction Specific Speed (Part One)
The Eighth in a SeriesNormalizing NPSHOur attempts to normalize or classify water turbine hydraulic performance culminated in 1915 with the development of the specific speed concept, which was later...
Many pump designs fall into the positive displacement (PD) category, but, for the most part, they can be divided into two basic groups. The reciprocating group operates via pistons, plungers or...
