Selection of mechanical pumps
Thread Content
The dynamic seal leaks in the centrifugal pumps used in chemical plants were difficult to repair, and the environmental leakage detection results did not meet the standards. Which pump models do not leak and can meet environmental requirements?
One can choose magnetic drive pumps or leak-free pumps, such as leak-free chemical pumps and shielded pumps. These pumps do not require dynamic seals in their design, which prevents leakage issues and meets environmental regulations. .
If the cost-performance ratio is favorable, modify the mechanical seal by replacing it with a double-end face mechanical seal or a dry gas seal； Another option is to use leak-free pumps such as magnetic pumps, shielded pumps, and diaphragm pumps.
Was the problem solved? What is your medium? I’m facing the same issue; the medium is highly solid-containing and highly acidic, which causes leakage from the mechanical seal. Please reply
Junming Machinery can provide professional renovation solutions, including the modification of mechanical seals or high-power magnetic drive pumps.
What medium are you using? I’m not sure which brand you’re using; you might want to give DanDong Clone, Zhongmi Holding, John Crane, Fox, and Bergman a try – they are all quite good options. Either double-end face sealing or a shielded pump
