Abstract: There is provided an apparatus and method for dispensing a lime slurry from a storage tank. The lime slurry is continuously agitated in the tank. A conduit connects the bottom portion of the tank to an elevated pump. At least the portion of the conduit near the tank is at an angle of at least 30.degree. with respect to the horizontal so that lime particles will not tend to clog the conduit. The passage portion of the pump is continuous and straight to also reduce the probability of clogging. A source of fluid under pressure is connected to the output of the pump providing a back pressure on the pump, increasing the velocity of the slurry, and further diluting the slurry.
