We celebrate 20 years as the pump industry’s most complete and reliable source for information about pumps, rotating equipment and the entire system surrounding the pump.

Part 1 (Pumps & Systems, August 2012) discussed an example in which neglecting corrections for velocity head and gauge elevation did not introduce significant errors in the calculations.

Aug. 28, 2012 – With Hurricane Isaac reaching Category 1 strength today just after noon (CST) in the Gulf of Mexico, the nation prepares for its impact. The pump and oil and gas industries will be affected and have already taken precautions.

As we all know, optimizing pumping systems improves pump performance, minimizes costs and decreases downtime. But how is it achieved?
For a quick estimate of pump head in the field, the discharge pressure gauge is read.

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.
