Dosing Pump 12V

A dosing pump that squeezes liquid along a flexible tube with rollers, so the fluid never touches the pump mechanism itself. That makes it the right choice for chemicals, nutrient solutions, aquarium dosing and any liquid that would corrode or contaminate a conventional pump. Volume delivered is proportional to run time, so an Arduino can dose a precise amount simply by running the motor for a calculated period. The tube is a wear part and needs periodic replacement. Liquid never contacts the pump mechanism; Precise dosing by controlling run time; Handles chemicals and nutrient solutions safely; Self-priming and can run dry without damage
