Abstract
An apparatus for mixing or blending chemicals includes a dedicated pump for each type of chemical to be blended, such as one pump for water-based chemicals and another pump for oil-based chemicals. Each pump preferably operates in a fast speed when delivering the majority of a particular chemical into a vending vat. When the desired amount of a chemical has almost been pumped into the vat, the pump switches to a slower speed to add the remaining amount. Then, the pump is reversed to clear the chemical from the line so that another similarly based chemical can be pumped through the line into the vat.
