When it comes to pumping systems that have varying demands, many engineers are hesitant to size the pump to less than the highest possible load. While this is certainly conservative from a flow standpoint, the downside is that additional costs are incurred to mitigate what might be a small risk.
Proper lubrication is a key to long, trouble-free life of centrifugal pump bearings. In recent years, the issue of lubrication has received renewed attention from pump users in chemical plants, pulp and paper mills, refineries and other industries.
This is the first article in a five-part series.
In the world of psychology and specifically in the area of introspective issues, it is often declared that, “what you resist will persist.”
Working with chemicals can pose a host of dangers. Those in the process industries must take every step possible to protect employees and others from hazardous conditions.
Pumps are stupid. A centrifugal pump is simply a machine, where for a given set of fluid properties, impeller geometry and operating speed it will react to the system in which it is installed.
Since the motor performance defines the amount of shaft power developed as a function of shaft speed, the pump’s power curve is the motor’s power curve.
In this column, we will look at ways to measure the flow rate within a piping system without the expense of the custody transfer meters or the complexity of a flow control loop.
Learn the advantages and disadvantages of five 1EEE 519-compliant VFD technologies—often referred to as clean power drives—and how each addresses the impact of non-linear loads and harmonics.
