Peristaltic pumps create a steady flow for dosing and blending and is able to pump a variety of fluids, ranging from toothpaste to all sorts of chemicals. They are widely used in water treatment, chemical processing, and food processing industries.
e. Gear pumps
Gear pumps transfer fluid by gears coming in and out of mesh to create a non-pulsating pumping action. They are able to pump at high pr…

C. Fire hydrant systems
Fire hydrant pump system (also known as a fire pump, hydrant booster, fire water pump) is technically not a pump but a system by itself. The hydrant booster pump usually con…

A pump is a device that moves fluids by mechanical action, from one place to the other. It is, essentially, the earliest form of machine, dating back to ancient Egypt.
Classification of Pumps
Generally Pumps classification done on the basis of its mechanical configuration and its working principle.
Classification of pumps mainly divided into two major categories:

What is Fuel?
Fuel is any compound that has stored energy which is captured in chemical bonds and released during oxidation.
What is Combustion?
Combustion refers to the rapid oxidation of fuel accompanied by the production of heat, or heat and light.
The purpose of the various types of fuels like liquid, solid and gaseous fuels are available for firing in boilers, furnaces and other combustion equipm…

In general packed columns are most common equipment’s used for distillation, gas liquid absorption, sometimes liquid – liquid absorption too. These will be having some pro’s & con’s for these packed columns when compared to tray column. Below are some of them:
1. Packed columns are not effective for low liquid flow-rates,
2. Corrosive liquids can be handled in packed column effectively than pl…

On the previous discussion about boiler blowdown, it was mentioned that “If more solids are put in with the feed water, they will concentrate and may eventually reach a level where their solubility in the water is exceeded and they deposit from the solution. “
Why should we be concerned about boiler feed water?
Maintaining good feed water is an important and fundamental aspect of any stea…

View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked ≈ was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999.
