What exactly is a drilled well?

A drilled well consists of a hole bored into the ground, with the upper part being lined with casing. The casing prevents the collapse of the borehole walls and (with a drive shoe or grout seal) prevents surface or subsurface contaminants from entering the water supply. The casing also provides a housing for a pumping mechanism and for the pipe that moves water from the pump to the surface<br>The quality of materials used in well construction is an important factor. Casing must…

The Truth About Bottled Water That You're Not Supposed To Know

How to Increase Water Pressure From a Well Pump

Water pressure from a private home water well uses an electrical pressure switch for control. The pressure switch is located on the pressure tank of the water system. The switch...

6 Refinery Pump Maintenance Tips

Few industries can tolerate the unscheduled downtime of critical equipment. In refinery operations, it can have particularly serious implications. For an operation that runs 24 hours per day year-round, the losses—in both production and profitability—can be staggering. Rotating equipment—pumps, motors, compressors and pillow block bearings—represents a key refinery component that, without proper planning, can become a refinery’s Achilles heel. This article presents six tips that help…

What are hydraulic pumps?

Positive-displacement pumps, also called hydrostatic pumps, are used in fluid power motion control applications.

What Is a Circulating Pump?

If you use a boiler and that boiler creates hot water to heat your home, then you have red devices attached to some of your pipes. These devices are circulating pumps, and without them, the hot water generated by your boiler wouldn’t reach the heating outlets in your home.

Pump Cavitation And How To Avoid It

Cavitation is not a new phenomenon that can impact a pump system, but it is an issue that is growing. While no official figures exist, it is not misleading to say that in the last five years, cases of pump cavitation have increased markedly.

What Are the Types of Pump Curves?

Pump curves fall into several categories and each can be presented in slightly different ways.

What Are the Different Types of Industrial Pumps?

Industrial pumps can be grouped into centrifugal pumps and positive displacement pumps. Both play key roles.

Why Pump And Dumps Are Dangerous

I can't lie. I am really mad to be right about this.

What Is an EODD Pump?

An EODD pump is a standard double diaphragm pump driven by an electric motor rather than compressed air. In more complex forms, an EODD pump has integrated surge suppression, the ability to stall against back pressure and electronic control.

Tips on Regular Pump Maintenance

Pump systems need to be regularly inspected and constantly maintained to prevent premature failure, losses in efficiency and increased operating costs.

How a Pump-and-Dump Scheme Works

Pump-and-dump is a scheme that attempts to boost the price of a stock through recommendations based on false, misleading or greatly exaggerated statements.

What to know before specifying pumps

New pumps take up less space making apparatus more nimble and more capable of carrying non-suppression equipment

How to Calculate Pump Specific Speed

Despite its name, pump specific speed (NS) does not have much to do with the actual speed of a pump. While the rpm is included in the formula, the calculation’s main purpose is to establish the impeller’s shape and contour and to link this to other pump parameters—such as head rise to shutoff or the maximum achievable theoretical efficiency. The values of specific speed can change drastically, depending on the point on the head-flow curve at which it is calculated.
