For larger pumps, however, a more thorough examination, documentation and restoration of internal concentricities must be done.

Part 2 of Jim Elsey's column: The System Is the Boss.
Jim Elsey discusses two main factors that make up a system curve for a single centrifugal pump in an open system with a flooded suction.
It is important to know when a slow-speed pump may be a better option.

Guest columnist Heinz Bloch discusses how the industry can protect the environment
Bloch died at the age of 88 after complications due to cancer.
Columnist Lev Nelik shares his prognosis for the future of the industry.
In Bloch's latest column, he discusses how to navigate outdated standards.
In his latest column, Jim Elsey discusses his best recommendations.
A common misconception is that it is due solely to material strength.
In his latest column, Jim Elsey discusses the role critical speed plays in the pumping system.
Avoid this unique and specific type of cavitation caused by the impeller passing too close to the cutwater(s) on a volute-style pump.
Columnist Lev Nelik discusses pump selection in part two of this two-part column.
The placement of the cutwater, its length, thickness, leading edge profile and flow angle all have roles in the casing efficiency.
The impeller and casing must be matched to each other or the results will be a disaster.
