About 100 years ago, windmills were used to move water from one place to another. Today’s new and improved version of accomplishing that task are well pumps. Well pumps, like windmills are especially useful for crop irrigation, but they have numerous other applications.
Today, well pumps provide water to homes and farms. Not only can they be used to move water to distant locations, well pumps now transport oil, natural gas, and chemicals. There are basically three different types of water well pumps. 1) centrifugal pumps, 2) jet pumps, and 3) submersible pumps.
The difference between these pumps has to do with the depth of water in which they will be installed. Non-water well pumps also include well stimulation pumps. No matter what type of pump is used, the components on the output side of pumps are very much alike. Well pumps do not run continuously. Instead they transport water or other materials to a storage tank where air compression takes place. The air pressure in the tank then moves the water to it’s destination. When the air pressure reaches a pre-determined level in the tank, the well pump activates again, replenishing the tank.
Well pumps are generally used to carry potable water from below the surface of the ground for residential or commercial use. Various types of well pumps are available including submersible pumps, jet pumps, bladder pumps and mud pumps. Primarily, well pumps are used for well water collection, but they are also used to unload storage tanks, barges, and small tankers.
Natural gas, oil, ash slurries, chemicals, and wastewater represent a few other substances that are extracted by well pumps. They are powered by a wide variety of sources including hand well pumps, solar well pumps, AC/DC power, gas or diesel engines, and hydraulic power. Well pumps are employed in commercial service industries, construction, mining, and fuel production concerns, although their primary use remains in water distribution services for municipalities and agriculture.

|Choosing Well Pumps||Energy Saving Tips|
for Well Pumps
Well pumps typically draw a lot of energy. The precise amount depends on the pressure and size of the pump, the depth of the water table, and the amount of water used in a given household. To ensure optimal energy conservation for well pumps:
Power For Well Pumps
Standard well pumps which run on AC (alternating current) are the least costly. Also, they pump more liters per minute than most other sources. These well pumps usually require 230 volts of AC 1 phase electricity and come in the form of two or three wire units. Three wire units possess a control box including a motor starting relay, thermal overload, and capacitors. They are surface mounted, permitting easy access. Two wire units do not have an external control box. Instead, all of the components are housed inside the motor.
The traditional windmill remains useful for powering well pumps. The pump and the wind generator are coupled to make the system function. However, problems occur if wind is negligible for a couple of days. On occasion, the leather seals used on this pump need to be replaced. The Bowjon windmill system uses compressed air to power well pumps. This method requires a minimum of maintenance, making it cost effective.
Strangely enough, water is used to pump water! Water pressure from local streams power Ram well pumps. Water flows down a pipe and then is turned off abruptly, resulting in a pressure surge which spurts water uphill. The degree of water propelled upwards is dependent on pump size, amount of lift, and amount of fall. Best equipped for use in mountainous terrain, high lift well pumps require a greater fall into the pump, but retrieve a much larger quantity of available water.
Solar well pumps do a great job of pumping water even though they are costly. Obviously, they work anywhere the sun shines, but are unable to pump as much water in cloudy weather. Well pumps that are powered by the sun use photovoltaic panels which seize rays, and are then converted into DC (direct current). The direct current then gives power to the pump.
