Power generation, oil and gas refining, and chemical processing are just a few of the industrial uses for canned motor pumps. As they don’t have a conventional shaft seal, which is a common source of maintenance and dependability problems, they are special in this regard. Nonetheless, regular maintenance is still essential to guarantee the durability and effectiveness of your canned motor pump. We will discuss some maintenance tips for your canned motor pump in this blog post.
Recognize the Fundamentals of Your Canned Motor Pump
It’s crucial to comprehend the fundamentals of your canned motor pump before going into maintenance procedures. The rotor, stator, and motor of a canned motor pump are all housed in a hermetically sealed casing. There is no need for a shaft seal because the rotor is directly attached to the motor. For tasks like handling dangerous or hazardous products, where leaking is unacceptable, canned motor pumps are frequently employed.
Canister motor pumps can have a single stage or numerous stages and can be submersible or not. Your precise maintenance procedures will depend on the type of canned motor pump you have.
Regular Examination
Regular inspection is the first step in keeping your canned motor pump. Checking for leaks, strange noises, and excessive vibration is all part of this. It’s critical to repair any of these problems right away if they are found in order to keep the pump from suffering more harm.
Regularly checking the pump’s temperature is equally crucial to keep an eye out for problems. It’s critical to make sure that the temperature stays within the advised range because excessive heat can harm the pump’s components.
Cleaning
Over time, debris accumulation in canned motor pumps can reduce their efficiency. To keep this dirt from harming the pump’s parts, routine cleaning is required.
Your canned motor pump’s type will determine the cleaning procedure. Disconnecting the power source and removing the pump from the liquid it is submerged in are the first steps for submersible pumps. Using a high-pressure water stream or a chemical cleaning solution, the pump should be completely cleaned.
Similar steps apply for non-submersible pumps, although the pump can be cleaned on the spot. Disconnect the pump from the piping system before using a cleaning solution or high-pressure water stream to flush out any accumulation or debris.
Swapping out the bearings
A canned motor pump’s bearings may degrade over time, increasing vibration and lowering performance. The bearings should be frequently inspected and changed as necessary.
It can be difficult to replace the bearings in a canned motor pump, thus a technician should usually handle this task. It’s crucial to get in touch with an experienced expert to handle the work if you think your bearings need to be replaced.
Upkeep of the Motor
To maintain long-term function, the motor in a canned motor pump is a crucial component that needs routine maintenance. It’s crucial to frequently inspect the electrical connections on the motor to make sure they are tight and stable.
Canned motor is crucial to keep an eye on the motor’s temperature in addition to monitoring the connections. It’s critical to make sure that the temperature stays within the recommended range because too much heat can harm the motor.
Lubrication
To ensure that the working elements in your canned motor pump operate smoothly and effectively, lubrication is crucial. The manufacturer’s recommendations for the kind and frequency of lubrication should be followed because excessive lubrication can harm the components of the pump.
Depending on the sort of canned motor pump you have, you will need to lubricate it. The lubricant is normally provided by a fill plug or grease fitting to submersible pumps. The lubricant is normally added through the bearing housing or other access points for non-submersible pumps.
It’s crucial to confirm that the lubricant being used complies with the manufacturer’s specifications and is suitable with the pump’s parts. Over-lubrication can result in lubricant migration into the motor windings, reducing efficiency and raising the temperature.
Dispose of Worn Components
Canned motor pumps contain worn parts that eventually need to be changed, just like any mechanical device. They consist of diffusers, impellers, and other parts that degrade with time.
It is a good idea to have a backup plan in place in case you need to cancel your plan at any time. In addition to lowering performance, worn parts might harm other elements of the pump, creating more maintenance problems in the future.
Suitable Storage
Canned motor pumps should be stored carefully while not in use to protect the components of the pump. This entails safeguarding the pump from the weather, making sure it’s kept in a cool, dry place, and making sure the pump is correctly supported to prevent harm to the housing.
In addition to these fundamental storage guidelines, it’s crucial to abide by any particular storage advice provided by the pump’s manufacturer. These can contain guidelines for draining the pump or safeguarding the seals while storing.
Conclusion
Your canned motor pump’s long-term performance and dependability depend on proper maintenance. Frequent inspection, cleaning, and lubrication can avoid faults before they become severe problems. Furthermore, extending the life of your pump and ensuring correct storage will help you avoid expensive future repairs.
It’s crucial to seek advice from an experienced technician or manufacturer if you have any questions about maintenance procedures or require assistance with your canned motor pump. The Best canned motor pump manufacturer can run effectively and dependably for many years with the right maintenance.
