When you run your progressive cavity pumps, do you ever come across any kind of performance issues? It would appear that they are not operating with the same level of efficiency that they were in the past, would it not? After that, it is time for you to carry out an in-depth inspection and carry out a failure analysis so that you can determine the kind of repairing or troubleshooting that will be required to be carried out. After that, it is time for you to carry out an in-depth inspection and carry out a failure analysis. In light of this, the questions that need to be asked are as follows: where to start, and how to go about accomplishing what needs to be done. The condition of the stator, which is one of the most important components in progressive cavity pumps, needs to be inspected and analyzed before any other major inspections can proceed. The stator is responsible for regulating the flow of fluid through the pump. This is due to the fact that the condition of the stator needs to be identified first before any other significant inspections can be carried out. The reason for this is that the stator is one of the most important components, which is why it plays such a significant role. Because pumps are typically put into operation for the purpose of removing highly viscous, abrasive, and/or corrosive substances, the stators of the pumps are susceptible to varying degrees of wear and other types of damage. This is because of the nature of the substances that they are designed to remove. This is due to the fact that the pumps were developed specifically to remove substances of this nature. Even a relatively minor problem with the stator can have a significant impact on both the overall performance and the functioning of the progressive cavity pump stator. This can be the case even if the problem is relatively minor. This is something to keep in mind even in the event that the issue at hand is a relatively minor one. In the following paragraphs, we will talk about the steps that need to be taken in order to inspect the stator from the inside as well as from the outside in order to determine whether or not it needs to be replaced.

During the inspection of the Stator of the Progressive Cavity Pump, it is necessary to collect the information listed in the following paragraphs:

It is possible for the stator in the pumps to become damaged or stuck in an unfavorable operational environment, which can lead to a variety of performance issues. If this happens, the pumps will not function as effectively. In the event that this takes place, the pumps will not operate as efficiently. It is of great assistance to be able to recognize the problem in advance in order to be in a position to provide the appropriate services for maintenance, reworking, or repairing in the event that a comprehensive inspection is carried out. A thorough examination of the stator covers as seen from the outside can provide information regarding the following items, provided that it is done so carefully:

For the purpose of future reference, the serial number of the stator as well as the type of material that was used in its construction are both documented in this section.

The presence of any kind of foreign material, such as sand particles or paraffin, can be interpreted as evidence of adulteration.

Stator pull conditions

The elastomer that is being utilized is undergoing a procedure that causes it to swell.

On the other hand, an examination of the components found within the stator itself is carried out. These components are among those that are looked at, but the list is not exhaustive.

Making use of a variety of instruments for measuring in order to investigate the dimensions of the stator elastomers

A measurement of the elastomer's degree of hardness should be taken in order to establish the level of expansion that has taken place in the elastomer.

The behavior of wear and tear is currently the subject of research.

It will be necessary to conduct research into the rate at which resistive heat is produced in the stator windings of the motor.

performing an examination to establish the degree of deterioration and damage brought on by abrasion to the material.

After all of the tasks that were described earlier have been finished, a thorough inspection of the stator's individual components will be carried out. The following stator components are inspected, and the extent of any damage that has occurred is graded according to how severe it is: minor, moderate, or severe.

a covering that guards against damage caused by cracks and corrosion

Elastomer that was developed specifically for use in conditions that involve wear, swelling, blistering, hardness, tearing, contamination, scratches or grooves, brittleness, or burning.

in reference to the process of recovering costs associated with losses and damages.

In the event that the bar breaks or is misplaced, it should be marked with some kind of identification.

After the completion of the inspection, the individual who was involved will be responsible for writing a comprehensive report in which they will describe the severity of the damage that was sustained by the stator. It is much simpler for the person who is troubleshooting or repairing the issue to evaluate the level of damage that has been done because the report contains photographs of the parts. If the level of damage is low to moderate, then the appropriate maintenance or troubleshooting procedures are carried out in order to restore the stator to the high standard of performance it had previously maintained. If the level of damage is severe, then the stator will need to be replaced. In the event that the damage cannot be fixed, the most prudent thing to do would be to replace the component in question as soon as possible. Taking this course of action would be the wisest thing to do. It is of the utmost importance that you purchase these replacement components either directly from the original equipment manufacturer (OEM) or from a reputable provider of OEM parts or aftermarket spares. Buying them from an OEM will ensure that they are of the highest quality. MXQ is well-known for being one of the most reliable distributors of Bornemann, Netzsch, and Moyno equivalent progressive cavity pumps, in addition to the spare parts for those pump stator. MXQ also carries a comprehensive inventory of Bornemann, Netzsch, and Moyno progressive cavity pump replacement parts. Additionally, MXQ maintains an extensive stock of replacement components for Bornemann, Netzsch, and Moyno progressive cavity pumps.
