Process Engineering: Can't find the pump performance curve? Contributor Ross Mackay gives a simple rule of thumb to follow when determining the status of your older pumps.
In this web exclusive on ChemicalProcessing.com, pump expert Ross Mackay says a key to a pump's performance is to look at the control system it's running with.
Process engineering & chemical manufacturing: This article from Ross Mackay, an exclusive contributor to ChemicalProcessing.com and author of The Practical Pumping Handbook, discusses how you can save energy in your plant with proper pump selection.
As the new year starts up for contributor Ross Mackay, he is reminded of a pump start-up condition he encountered in a client's plant. There are only three things we need to do to start a pump.
Process engineering has made increasing use of angular contact bearings for pumping applications during recent years, but when used in a double arrangement, are they being installed properly in your pumps?
While magnetic drive pumps can cure some of your pump-related process engineering ills, it is important to know how to apply them to get the maximum results.
Improper startup can result in excessive temperature and radial loading, both of which can lead to lower pump reliability from problems such as seal and bearing failure. Consultant Ross Mackay describes the three steps that should be followed during pump startup.
Environmental concerns are fostering use of mechanical seals in a growing number of process engineering and chemical manufacturing applications. Here's a rundown on seal options.
Pipe strain is a condition that is closely related to equipment reliability. Learn about misaligned piping and what to do if its a problem in your plant.
That rumbling/rattling noise you hear from your pump is the symptom for any number of potential problems. The first step is identifying the problem. This article will help you determine what exactly is wrong with your pump.
Preventing pump problems before they happen is the best way to save costs, and it is the operators who are the key to your pump reliability.
The introduction of the larger bore seal chamber has provided two major benefits to mechanical seal operation, both of which contribute to increased reliability.
Pipe strain can cause premature failure of pumps. This can frequently be absorbed by a flexible pipe coupling... but only if that pipe coupling is properly installed. Merely putting it into the line without any support, will not achieve any significant relief from the pipe strain. In order to ...
"Bad actor" pumps are those pumps that have trouble with frequent and repetitive failures. In many cases, the source of the problem is an ANSI pump trying valiantly to handle a liquid well beyond the range of its design rating.of 300 degs. F.
