Grundfos looks to maximise efficiency of all Grundfos pumps and improve the value of their Grundfos products by reducing downtime costs. An important method of increasing the lifetime of well pumps is making sure that the alignment of water pumps is correct. Alignment refers to when the shafts of a water pump are not in line with each other, alignment is a very important part of efficiency and ensuring that the pumps are able to last for a long time and reduce the number of times water pumps break down.
Misalignment of water pumps leads to several problems even with well designed water pumps with excellent mechanical seals and components. Misalignment of pumps leads to several problems such as vibration and failure in mechanical seals, even if the seals are designed to be flexible to small changes in the positioning of pump shafts. Misalignment of water pumps causes other problems such oil leakage and incredibly high temperatures of the water pumps. Hence, it is very important that Grundfos technicians take steps to ensure that Grundfos pumps are designed to minimize misalignment and that instructions for installing the water pump are as detailed as possible.
Types Of Alignment And How To Prevent It
When it comes to aligning pumps, pump owners should know that there are two different types of misalignment:
- Parallel misalignment
- Angular misalignment
To reduce the chances of misalignment of water pumps, it is important to ensure that well pumps are properly installed. Pump professionals should follow the specified instructions when installing. This is because the key to proper alignment in water pumps is with correct procedures in installation. Grundfos pumps to make sure that pump shafts are properly aligned with one another. An important process in pump installation is a procedure called 'bolt bound' which is used to resolve the problem is a driver or pump cannot be moved further, the solution is fill weld existing bolt hole and then re-drill and re-tap.
