There are a variety of processes in which progressive cavity pumps have the potential to play a significant role. You are likely to find advantages and disadvantages for this industrial pump design, whether you are pumping food and beverages, oil, sewage, viscous chemicals, or other types of liquids. You can also find scenarios where it is suitable. Engineered Systems and Products (ESP), in conjunction with our other partners such as PCM, is committed to meeting all of your pumping requirements through the provision of sales and service support. This refers to progressive cavity pumps in addition to a wide range of other types of industrial designs. Let's take a deep look at this detailed sort of positive displacement pump and the wide variety of uses that it may be put to. Both of these components are vital to the operation of an eccentric solenoid pump. In most cases, a double helical hole will have a helical rotor inside of its center. There are still cavities even after the rotor has completed its rotation inside the pump body.
As the helical rotor turns, the fluid will be contained here while it is in motion. The rotation of the rotor, which is responsible for pumping fluid, does not alter the form of these cavities in any way. However, in order to ensure that they function in an effective manner, it is vitally important that these pumps be made with precision. That is precisely what you get when you delegate your pumping demands to the ESP and let it take care of them for you! The kind of substance that is pumped into this key-like structure has the potential to have a significant impact on its appearance. A pump's lifespan that is shortened by abrasive fluids is likely to be shorter due to the precision design of the pump, which features very high tolerances between the rotor and the body. Over time, solids will continue to damage the various internal components of the pump. On the other hand, when it comes to working with viscous fluids, progressive cavity pumps have a pump life that is both long and reliable. This is due to the fact that the fluid that is being moved also serves as a lubricant for the components that are found internally. Because of the pump's unique construction, it possesses a number of benefits that make it an extremely appealing choice for a variety of applications.
- One of its strengths is that it is able to manage both delicate and thick liquids without issue. Because of the minimal levels of shear that are applied to the material by the pump, materials that are more susceptible to shear will not be impacted.
- When this occurs, the flow rate is directly proportional to the speed at which the pump is functioning. This indicates that the flow rate can have its ease of regulation simplified by the fact that the speed of the pump can be altered.
- Mounting screw pumps have a large suction capacity and are completely self-contained, which are also additional benefits of using these pumps. Because of this, you won't need to worry about forgetting to reprime the pump, which is a good thing. You won't waste any time doing so either.
- You will also test the pumps' ability to maintain a steady flow. In many different cases, which we will go over in a moment, having a flow that is steady but pulsating is something that is really desirable.
- Keep in mind that these pumps also have the capability of moving the flow in the other direction. Again, there are a great deal of circumstances in which doing something is either desirable or essential.
- Last but not least, helical screw pumps require almost little maintenance at all. These pumps have a long, reliable life and require little maintenance; this is especially true when they are used with viscous fluids that also serve as lubricants.
As was just said, the progressive cavity pumps that are manufactured nowadays are used in a wide variety of typical applications all over the world. Infusing meals and beverages is one of the most prevalent uses for this substance. Because of all of the benefits that come along with this pump design, it is extremely popular within the industry. It is also frequently used for pumping oil and coal sludge, pumping sewage, filtering rainwater, and pumping viscous chemicals, as well as a number of other applications. One further peculiar use for this material is in the construction of downhole mud motors for use in oilfield directional drilling. In a procedure such as this, the process actually goes in the other direction. The fluid that is being pumped is what ultimately generates the mechanical energy. This takes place when the fluid causes the rotating portion or the motor to spin, which may then be utilized to turn the directional bit.
Cement pumping, pumping of lubricating oil, pumping of marine diesel, and pumping of mining slurry are a few examples of further specific applications for progressive cavity pumps. If you are interested in employing a progressive cavity pump for a mode of operation that has not been described, please get in touch with the ESP team so that we can talk about your ideas. We are able to tailor a strategy to make your ambitious ideas into reality. Disadvantages of progressive cavity pumps are :
- There is a cap on manufacturing rates.
- There is a limit to the lifting capacity. It is important to keep in mind that the lifting capability of PC pumps with higher displacements is often substantially lower.
- It is only able to withstand temperatures up to 350 degrees Fahrenheit when combined with certain elastomers.
- sensitivity to environments, including fluids (stator may swell or deteriorate when exposed to certain fluids, including well treatment fluids).
- When it comes to wells that produce a significant amount of gas, they have a low volumetric efficiency.
- Failure due to fatigue can occur in sucker rod chains.
- Pumping dry for even relatively brief periods of time can cause irreparable damage to the pump stator.
- In directional and horizontal wells, thread erosion and tube erosion are potential issues that can arise.
- To replace the pump in the majority of systems, the tubing must first be removed.
- Applications that operate at high speeds are susceptible to having vibration issues.
- In applications involving waxy crude, wax management can be a challenging issue.
- Inadequate experience in the development, installation, and operation of systems, particularly in specialized domains.
