Abstract
A multi-purpose large capacity pump includes a cylinder having top and bottom ends closed by a top lid and a bottom lid. The top lid is provided with an inlet port that is in communication through a first one-way valve with an interior space of the cylinder. The bottom lid includes a second one-way valve in communication with the interior space of the cylinder. An output tube connects between the second one-way valve and an outlet port of the top lid. A protection enclosure is set around an outer circumference of the cylinder and a base is provided to fix and support the bottom end of the cylinder. A pull bar extends through the top lid into the cylinder to allow an inner end thereof to couple to a piston. The pull bar has an outer end to which a handle is mounted.
