Abstract

(BF Eldridge) A simple device is described to pump insecticide concentrates from a tank into a larger mixing tank. There are no moving parts in the combination pump and meter. Pumping action is due to a difference in atmospheric pressure created by a water tank located above the concentrate tank.
