Abstract:
A piston pump arrangement that disables operation of the pump in the absence of an inlet liquid and also to a piston pump arrangement useful to discharge liquids from at least two sources and to disable discharge of all of the liquids when supply of liquid from at least one source is empty.

Claim (Index 3):
The pump arrangement of  claim 1  including:\n a first float valve across the first conduit between the first reservoir and the first chamber, \n the first float valve including a first float movable between an open condition and a closed condition, \n the first float buoyant in the first fluid, \n the first float assuming the open condition when a level of the first fluid in the first conduit is above a predetermined first fluid float level, \n the first float assuming the closed condition when the level of the first fluid in the first conduit is at or below the predetermined first fluid float level, \n with the first float in the open condition, the first float valve permitting for flow in the first conduit from the first reservoir to the first chamber, \n with the first float in the closed condition, the first float valve preventing flow in the first conduit from the first reservoir to the first chamber, \n with the first float in the closed condition, reciprocal movement of the first piston creates a vacuum condition in first chamber between the first float valve and the first piston.
