BRS Top Off Dosers are intermittent duty pumps and not meant for continuous operation. We recommend on/off cycles under a few hours to maximize life span. This is a higher RPM motor than the BRS 2 Part Doser and may make a small amount of noise in operation but is much quieter than most dosing pumps in this flow rate range. Mounting the pump to the inside of a wooden stand will amplify sound.
