ABSTRACT:
A joint for a fluid pumping apparatus includes a body having a passage defined in the body and extending through the body. A through hole is longitudinally defined in the body and extends through the body. A container is mounted to a lower end of the body, and the passage and the through hole communicate with the interior of the container. A connecting seat in mounted to an upper end of the body and has hollow connector communicating with the through hole in the body. A hose has a first end connected to the hollow connector and a second extending into a pail containing fluid. Consequently, the fluid in the pail can be sucked into the container when a compressed air flows through the passage in the body.
