A manually operative siphoning pump apparatus for transferring liquid from one container to another container. The siphoning pump apparatus has a hollow cylindrical pump body through which liquid from one container to another can flow and a bellows attached thereto for establishing a vacuum within said pump body. The hollow pump body has a inlet pipe and an outlet an elongated flexible hose or tube connected to each of the pipes. The siphoning pump apparatus has an axially movable valve within the hollow pump body for initiating, controlling and shutting off the flow of liquid through the pump body during the siphoning process and, hence, from one container to another container. The axially movable valve has a cylindrical head at one end thereof and a connector at the opposite end thereof for fixing it to the bottom of the bellows. The axially movable valve is manually controlled by an elongated lever arm pivotally attached to a housing handle at one end and fixedly attached to the bottom of the bellows.
A manual siphoning pump apparatus for transferring liquid from a first container to a second container, said appararus comprising an elongated, hollow pump body, an inlet pipe extending from and communicating with said pump body, an outlet pipe extending from and communicating with said pump body, an elongated flexible hose or tube connected to each of said inlet and outlet pipes, a poppet valve axially movable within said hollow pump body and operable to allow and prevent liquid from passing from said inlet pipe to said outlet pipe through said hollow pump body, a bellows mounted to and communicating with said pump body, and operating means connected to said poppet valve and said bellows for axially moving said poppet valve and said bellows such that said bellows is usable for initiating a flow of liquid through said hollow valve body when said elongated flexible hose or tube on the inlet side of said pump body is at a higher elevation than said elongated hose or tube on the outlet side of said hollow pump body.
A siphoning pump apparatus for transferring liquid from one container to another, said apparatus comprising a hollow, substantially cylindrical, pump body which is closed at the top and open at the bottom, said pump body having a sidewall with an inlet and an outlet connector, a handle attached to said pump body, an elongated flexible tube being sealingly connected to said inlet connector and an elongated flexible tube being sealingly connected to said outlet connector, a bellows sealingly attached to the bottom of said pump body, a lever connected between said bellows and said handle, an elongated valve within said pump body and said bellows, said elongated valve having a substantially cylindrical head within said pump body for controlling and shutting off the flow of liquid through said pump body during a siphoning operation, and said valve being axially movable within said pump body and operative by means of said lever to control and shut off the flow of liquid through said pump body.
A siphoning pump apparatus for transferring liquid from one container to another container, said apparatus comprising:
