In pump literature, much has been written and continues to be written about NPSH (Net Positive Suction Head) and cavitation. As career pump engineer, I will share some of my knowledge and experience on pump NPSH testing, particularly a few practical matters that may not be covered in the extensive literature on this subject. Terminology […]
Pump lead times – what to expect
Introduction We live in a world of convenience and instant gratification. When the Wi-Fi goes down, Netflix for that evening is out. This is a serious first world problem. Not surprisingly, initiates to the field of industrial pumps, motors, and valves are often dismayed by the lead times for this […]
The User’s Role in Pump Reliability
This introductory 20 minute webinar, with Randal Ferman of Ekwestrel Corp, discusses what operations and maintenance can do to improve pump reliability. Pump reliability directly affects process availability. When the cost of pump downtime in terms of lost production is factored in, the real costs of operating and maintaining pumps can be significantly higher than O&M costs […]
How Precise Is Your Pi?
The date March 14, expressed numerically as 3/14 or 3.14, provides an irresistible excuse to anyone with even a hint of nerdiness in them to associate it with the mathematical constant pi. So you ask ‘how does all of this attention to an abstract number relate to pumps?’ Well first of all, pumps have rotating […]
Pump Systems Optimization Course Concerns 40% Average Efficiency
(Press Release) Less carbon dioxide emissions, better reliability, and significant energy savings available when pumping systems are optimized. Randal Ferman, a lead editor for Optimizing Pumping Systems: A Guide for Improved Energy Efficiency, Reliability & Profitability, published by the Hydraulic Institute, is pleased that Bill Livoti will conduct the Pump Systems Optimization Course on October […]
Horizontal or Vertical?
In selecting a pump for a given application there is sometimes the option of choosing either a vertical or a horizontal shaft pump arrangement. For instance, in a process plant certain product transfer applications might be performed by a can-type vertical pump, or a vertical in-line pump, or a horizontal process pump. Large capacity cooling […]
