Which pumps & membranes are best for CED bath?

Q. Dear all,
Which pumps are best for CED ⇦ huh? circulation, Filtration?
Also which membranes are best for CED coating? Currently we have 5000 liter bath capacity. We are facing continuous pump seal leakage issue in spite of regular flushing with the help of DM water. Quarterly we are forced to purchase new membrane. Very costly.
