I just received two BRS 1.1 dosers. Both ran "quiet" when I first turned them on but then changed to a much louder clacking sound after a few minutes. Both also deliver about 2-2.2 mL/min which is not what I expected. If they are consistent then that's fine, but I'm wondering if this is actually the right pump. Either the motor is different or the peristaltic tubing has increased in diameter significantly.
The sound is the same whether or not the pump tubing is installed on the rollers. There's no issue of binding.
I've sent an email to BRS support but wanted to ask any reefers here if this sounds normal? I'm not going to be able to use these if so.
