This was the most well attended EASA event that the Pumps & Systems team can remember. Many exhibitors we talked with felt the same way, describing the large crowd of attendees as steady, active and inquisitive.
Xylem continues ITT's water focus and continues to grow.
Equation versus actual measurement of radial thrust in centrifugal pumps.
Keep pipes and pumps aligned to keep your pumps working longer.
Factors to consider when deciding the priority of pump efficiency.
Pumps & Systems introduces an extended Readers Respond section, which includes end-user challenges with helpful solutions from manufacturers and other industry experts. Tell us about the maintenance, reliability or repair issues that trouble you.
From presses to collectors, there are several methods available for removing debris from wastewater.
Curve shapes reveal a pump's range of peak efficiency.

(May 2012) We continue to read reports about renewable energy sources building momentum as a power generating vehicle. However, according to the U.S.

The late Charlie Jackson, vibration expert at Monsanto, once told me that he was unaware of any centrifugal pump manufacturer that knew how to calculate the hydraulic axial thrust produced within the liquid ends of their pumps.

Standards for repair will begin with a standard for vertical turbine pumps.The pump industry is undergoing renewed interest in the technical aspects and quality of repairs.
The performance of a centrifugal pump with a trimmed impeller will follow the affinity laws as long as that trim is relatively small.
If most of the attachment boundary were along the short edge of the plate, the natural frequency of resonance would be somewhat less than if the plate were attached mostly along the wide edge.

(March 15, 2012) - Pumps may be the heart of industry, but the it's the people who work with the pumps who truly provide the heartbeat.

ITT Goulds Pumps continues its worldwide effort to celebrate pumps as the “heart of the industry” with several activities leading up to April 10, 2012, which it is declaring an official Pump Appreciation Day. Pumps & Systems has joined this effort.
(Feb. 14, 2012) Thanks for all the kind; productive; and in some cases, critical feedback about our January 2012 feature, “The History of Pumps.”
How repair standards should be evolving
In this multi-part series, we will investigate several aspects of centrifugal pump efficiency. First of Five Parts
The McGraw-Hill scientific dictionary [5] states that a volute is "a spiral casing for a centrifugal pump... designed so that speed will be converted to pressure."
Specific speed is a concept developed for water turbines1 in 1915, which was later applied to centrifugal pumps (Stepanoff, 1948). Specific speed is a way to “normalize” the performance of these hydraulic machines.
