Sealing flushing type for pumps used in the production of ethylene glycol oxalate from syngas
Thread Content
Hello everyone. Since dimethyl oxalate crystallizes at 54°C, I would like to ask what type of sealing is used for the pumps that transport pure dimethyl oxalate in your ethylene glycol plants? What kind of isolation fluid was chosen? We would like to choose Plan01+53B. Thank you all.
The project is time-sensitive, so please help out and get actively involved. Thank you.
Could you tell me about the sealed flushing type? Thank you
Didn’t you write 53B above?
In addition to series connection under pressure and using methanol as the sealing fluid, do you also use self-flushing? Like plan01 or 11.
There is one option where you can use just PLAN53A, or you can use PLAN01+53A. Magnetic drive pumps can also be used.
Thank you for your reply. The owner is now considering using only Plan53B, which is pressurized, and does not want to use Plan01 at the same time. Could self-flushing easily cause damage to the mechanical seal?
Pumps can be kept warm with hot water; magnetic pumps and shielded pumps are recommended
