A submersible pump uses a motor in a watertight housing to drive a pumping mechanism that pushes a column of liquid to move to another location. The sealed housing allows the pump and motor to be placed inside the fluid it pumps without damaging the electric motor.Know More
The submersible pump includes a series of impellers that are stacked to lift the water. When the motor starts, these impellers turn like a boat propeller to force the water to move. Because the fluid is pushed, the submersible pump moves fluids over large differences in vertical height. To further improve the lift, it is possible to include additional submersible pumps along the line.
Submersible pumps have use in many applications other than supplying water. Single-stage pumps with specially designed impellers pump sewage, sludge and drainage. They also offer an effective means of mining petroleum from a deep well.
Most shallow wells use jet pumps. These pumps create a suction by evacuating air from the pipe. The weight of air on top of the water at the bottom of the well pushes the water into the evacuated area and moves it to the surface. Atmospheric pressure limits jet pumps to a 25-foot depth.Learn more about Plumbing
To prime a pump, first gather 2 gallons of water with which to prime the pump. Next, cut off the power to the building, and relieve water pressure from the system. Remove the priming plug, and pour the water into the pump through a funnel.Full Answer >
A flow switch is a mechanical gadget used to control the flow of liquid, air or steam. The switch works by sending a trip signal to another device in the system, such as a pump, to protect it from damage and for cooling circuit protection.Full Answer >
In order to troubleshoot a water well pump, follow the troubleshooting tips outlined in the owner's manual. Ensure the power is off at the breaker before performing any troubleshooting tasks.Full Answer >
To prime a shallow well pump, turn off the power and the pump control valve. Remove the priming plug, fill the reservoir with water and replace the plug loosely. Run the pump, and repeat the process until the water flows smoothly. Replace the plug, and turn the control valve back on.Full Answer >
