plant. Its purpose is to convert energy of a prime mover (a electric motor or turbine) first into velocity or kinetic energy and then into pressure energy of a fluid that is being pumped. The energy changes occur by virtue of two main parts of the pump, the impeller and the volute or diffuser.

Do you need grease or oil for your bearings? Although there are upsides to both lubricants, you must consider your application. G rease or oil for rolling bearing lubrication helps smooth the way toward reliable performance by preventing metal-to-metal contact between a bearing’s rolling elements, raceways and cages. Besides separating the rolling and sliding contact surfaces in a bearing ...
Paradoxically, the grease gun, designed in 1916 to save bearing lives, has been used to kill them ever since. We can take advantage of this “Lethal Weapon” knowing that by design, a bearing only requires 30% to 50% of its cavity to be filled with grease to provide an optimal lubrication state.

Grease needs to maintain its consistency under high shear conditions. The shear stability test measures the softening of grease when sheared for 10,000 or 100,000 double strokes with a grease worker. Loss of less than one NLGI grease grade signifies a stable thickener under high shear conditions. Compatibility

Industrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable by-product. After treatment, the treated industrial wastewater (or effluent) may be reused or released to a sanitary sewer or to a surface water in the environment.. Most industries produce some wastewater.Recent trends have been to minimize such production or ...
These days, equipment is running faster and hotter than ever to meet productivity demands—and higher performance lubricants are required to meet these demands.Synthetics offer that level of performance. Synthetics aren’t new; they’ve been around for 70 years.
GREASE OVERVIEW. Grease is not a single substance, although it may look and feel like one. Industrial lubricating grease, as opposed to the bear or goose grease used by our great-grandmothers, is an emulsion of several ingredients that are usually divided into three categories: a base lubricant or oil, a thickener, and various additives.
Finally, lubrication software was added to help establish efficient routes, schedules, responsibilities and accountability. While the plant had only 1,350 lube points, it managed to save $200,000 the first year and more than $160,000 per year during the next three years for a total of $680,000.
Oil and grease discharge, along with produced water, involves compliance with stringent regulations. For example, monthly average oil content of 29 ppm (analyzed by EPA 1664 A) in dischargeable produced water is allowed for offshore operations in the Gulf of Mexico. Oil and grease removal methods depend on the end usage of treated water and
But lubricants come in many types, chemistries and viscosities. From alcohol-thin oil to the thickest, stickiest grease, they all serve important purposes in operating valves. Oils, which are also the base ingredient for most grease compounds, come in many forms. They can be petroleum-, animal- or plant based, or they can be synthetic creations.
One of the most important things an operator can do for his machinery is to make sure it is properly lubricated. So what is a lubricant and how does it affect operations when used properly? This article will answer these questions and more by covering the fundamentals of lubrication. We will discuss ...
Ethanol (CH3CH2OH) is a renewable fuel that can be made from various plant materials, collectively known as “biomass.” Ethanol is an alcohol used as a blending agent with gasoline to increase octane and cut down carbon monoxide and other smog-causing emissions. The most common blend of ethanol is E10 (10% ethanol, 90% gasoline).
The Source For Reliability Solutions. In this Efficient Plant podcast, John Sander, vice president of research & development at Lubrication Engineers discusses the role of lubricants in air-compressor performance, maintenance, and reliability and how choosing the optimum lubricant and doing proper maintenance can result in notable energy savings.
P art I of this article provided a basic introduction to grease, with discussions of composition, types, properties and evaluation tests. Part II will focus on the correct grease for the application and some of the key criteria in the selection process, including compatibility, amount to be added and relubrication frequency.
