What is the approximate cost difference between ordinary centrifugal pumps of type 53B and canned motor pumps for transporting aromatic hydrocarbons?
Thread Content
For pumps used to handle aromatic hydrocarbons, where the medium is relatively clean, what is the approximate cost difference between using a standard centrifugal pump of type 53B and an enclosed pump, under the same conditions of flow rate and head?
Find a few pump manufacturers, then request quotes with their specifications, so that a comparison can be made.
Small pumps with leak-free designs have advantages, while high-power pumps with mechanical seals have advantages.
The amount of aromatic hydrocarbons is usually very large, making it difficult for shielded pumps to meet the requirements
For low-power applications, shielded pumps are chosen; for high-power applications, centrifugal pumps are preferred, as centrifugal pumps have higher efficiency
