Performance testing of centrifugal pumps
Thread Content
When purchasing a centrifugal pump, due to its high power rating, the manufacturer does not have motors large enough for testing, so they are forced to test it at 50% flow rate. How to determine whether the test results meet the requirements?
The manufacturers themselves don’t even have the ability to ensure that their pumps are of good quality; you still decide to purchase them? Are you crazy?
It’s not that simple. As mentioned before, the manufacturers have never actually used the power level recommended for this pump; so how can we ensure its long-term operation? Centrifugal pump testing is not merely about checking whether the flow rate meets the requirements. . .
Not every device needs to be tested.
No. If the factory can’t do it, take the experiment to the site for testing. The requirements remain unchanged, and the responsibility still lies with the manufacturer.
