Understanding this complex topic can help end users avoid common pitfalls.
Most experts agree that the majority of centrifugal pump problems occur on the suction side of the pump. Based solely on my experience, I would state the percentage is at least 80 percent, and in the...
Because cavitation is unavoidable in pump operations, understanding how to reduce it using NPSH calculations is necessary to maintain pump functionality and health.
Pressure gauges are inexpensive components that can predict the causes of poor reliability in centrifugal pumps and prevent costly repairs and downtime.
One of the supposed advantages of centrifugal pumps when compared to positive displacement pumps is their ability to operate across a wide flow range. Because a centrifugal pump operates at the...
This is the first article in a four-part series. Four part 2, click here. Second only to electric motors, centrifugal pumps are usually the simplest machines in a typical process plant. Pumps...
Higher temperatures reduce water’s lubricating effect and stress seal faces.
Pump sensors can improve system operation and detect dangerous faults.
This four-part series explains the reasons behind repeat pump failures and uses a real-world field example involving boiler feedwater pumps.
