ABSTRACT:
Apparatus for commingling liquid chemicals includes a mixing tank having a drain valve and a liquid container impaling head for piercing a container impressed thereon so that the container's liquid chemical contents will flow into the tank. A pump is operatively connected to the tank for transporting liquid such as water from an external supply into the tank. The pump is also operable for continuously recirculating liquid from the tank and back thereinto so as to commingle the liquid from the supply and the container. The pump's inlet is also connected to a second liquid supply so that liquid from a barrel or drum may be withdrawn therefrom and mixed in the tank. An extendible-contractible member is slidably arranged within a conduit to permit the contents of the barrel or drum to be substantially evacuated.
