Brs is a 2 roller on an armature industrial style pump made by a peristaltic pump company. Not the 3 roller friction driven osff of the motor shaft.
Ok, I understand - I don't know this unit.. Friction rollers dont make a difference for liquid drip back - its rather depend from number of rollers. Typically - more rollers, less possibility for left oump head in "open state" which allow to drip liquid (int sump or back into container).
