Small pump (50 mL/min and below) for pumping a suspension of carbon particles (up to 1 mm in diameter) without clogging or crashing (probably, lobe, screw or vane, peristaltic is not good)?
Thank you, Remi, can you point to a specific model? I contacted a couple of suppliers, they all suggested a peristaltic pump because of the small flowrate. The problem is we have the peristaltic pump, but it uses a very small diameter tubing for this low flowrate, which results in particle grinding by the rotating head and clogging.
