You may have seen pumps that move fluid from one place to the next by using pressure, but this is not how progressive cavity pumps work, even though this is what some people assume. Instead, these pumps have a corkscrew device inside of a chamber. Water or some other fluid is pulled through the chamber by the turning of the corkscrew. The water moves from one part of the blade to the next, always in the same direction, and is then expelled out the other side. Progressive Cavity Pumps are available from These are machine pumps that are very reliable because of their solid design and relatively simple features.

Often, progressive cavity pumps are used at the bottom of a slope or a pipeline. Fluid will come down the pipes, using the force of gravity and the design of the system, and then it will, in essence, fall into the top of the pump. A pipe will be connected at this juncture. The water will therefore by thrust onto the corkscrew, which will already be turning. It will then be pushed in whatever direction this is turning to pipes that come off the front and back of the chamber. The pump can be reversed with the flip of a switch to send the water in the other direction.

You can also use progressive cavity pumps as devices that are employed for drilling. This is often done when drilling wells because of the abundant supply of water. If water is pumped through the chamber with another pump, the corkscrew will be forced to turn. A drill bit can be attached to the end of the corkscrew so that it turns outside of the main chamber. This drill bit will then cut through sand, dirt, and rock. This is an eco-friendly manner of drilling because water is used.
