Hi All, I'm doing a project that needs dispersing regularly a non-corrosive liquid to a tank in small amount (20 - 30 ml each time). I need a pump that could run on d.c. so that my timer circuit can control its operation, an alternative is, I buy a pump head and install it to a d.c. motor myself. Does anyone know if there is any low cost d.c. pump or pump head available in the market? Thanks in advance!
