Abstract
The present invention provides a multipurpose pump apparatus of high achievement, which can continuously pump and convey liquid even containing a large amount of foams and can make high level defoaming function and degassing function, and pumped liquid sterilizing function, etc. The pump apparatus comprises a gas-liquid separating impeller disposed in a pumped liquid path of a primary pump for pumping liquid, a cavity receiver which receives the tail bottom of a tornado-shaped cavity produced by the rotation of the gas-liquid separating impeller to prevent the tornado-shaped cavity from extending, and vacuum means connected to a part in a vicinity of the center of the tornado-shaped cavity through a degassing path.
