Problem with pumps due to degassing of bleach

Hi Miseneo. Many suppliers of metering pumps are selling some small component to solve this problem. See example bhereafter: http://www.primaryfluid.com/accuvent.html http://pulsatron.salesmrc.com/pdfs/degassing_head_assembly_tech_sheet.pdf http://prominent.us/promx/pdf/auto_degassing_%20liquid_%20end_%20cut_%20sheet_%20colour.pdf Check with the supplier of your pumps
Hello, It is preferable to use peristaltic pumps rather than dosing pumps. ProMinent has a good selection.
Careful: peristaltic pumps are limited in pressure. Do not take the smallest one, as the pipe sometimes experiences fouling from crystals.
That's right: it must be below 4 bars at the injection point.
