Hi everyone, I am looking for a supplier of small pumps for the flow range from ~ 2 L/min to 20 L/min. The problem with the ones easily available online is that they are not corrosion resistant. Our pumps wore out in a few days by 5% H2SO4. So we are looking for gear pumps or centrifugal pumps (seems to be rare) that can deliver constant flow (no pulse) of acid or 30% alkali for prolonged period a 2 to 20 L/min flow rate. This is for our electrochemical cell experiments. Any suggestion can be of great help! Thanks a lot in advance!
