Water well pumps are the heart of the well system. They pump water upwards into your house or designated system. The most popular pumps used in wells are submersible pumps and jet pumps. Both pumps use centrifugal force to force water upward. Impellers are designed to create a vacuum that moves water upward through the casing of the well into the distribution system. The type of well pump required for your system should depend on the depth of the well and the quantity of water required for your household.
Submersible pumps
These types of well pumps have a wider range in depth. They can be used in both shallow and deep wells. Submersible water pumps are submerged into the well under the water level. Most of the energy of the pump is dedicated to pumping water upward instead of sucking it from above.
These pumps are cylindrical, housing the motor of the pump and impellers that drive water up into the drop pipe. They are durable, efficient and versatile in well depth and this is why most modern wells use submersible well pumps.
Jet pumps
These types of well pumps are placed above the ground. They lift water from the ground via the suction pipe which forms a vacuum with an impeller. It then pushes the water through a small nozzle. Jet pumps use water to move water and this is why they should be primed with water. You can use these water well pumps on rent.
Pressure tank
These are important well equipment used to maintain the pressure of the water throughout the distribution system. They store a reserve water supply to ensure it relieves the pump of continuous functioning. The size ranges from around forty gallons for domestic use to about twenty-one thousand gallons for industrial use. Pressure is created by moving water into the tank in conventional pressure tanks. The process continues until the air in the tank is compressed up to 60 psi. An air compressor ensures that the air pressure is maintained.
Pressure switch and control box
Submersible pumps aren’t meant for around-the-clock running. Using them continuously would cause unnecessary wear and tear on the pumping mechanism of the pump and would rack additional energy costs. The control box and pressure switch work in conjunction with the pressure tank to measure the pressure of the water in the well so that the pump is used when the pressure drops below a required level. Typical systems have a water pressure that ranges from 40 psi to 60 psi. The pressure switch turns the pump on when the pressure drops below 40psi. This brings the pressure back within the range. The pressure switch switches the pump off when the pressure is at the required levels.
Casing
A well casing is made of carbon steel, polyvinyl chloride, or stainless steel. It is a tube-shaped structure that is placed in a well to maintain the opening spanning of the well from the target groundwater to the land surface. It prevents dirt from contaminating the water and damaging the water well pumps.
