PUMP DEVICE

摘要

A high performance and general purpose pump device capable of not only continuously sucking and transporting even a liquid containing a large quantity of air bubbles but also providing a high degree of defoaming action, degassing action, and pumped liquid sterilizing action, characterized by comprising a gas-liquid separating impeller disposed in the pumped liquid flow passage of a main pump for feeding liquid, and a hollow receiver which receives the tail bottom part of a spout-shaped hollow generated by the rotation of the gas-liquid separating impeller so as to stop the extension of the spout-shaped hollow, the area of the spout-shaped hollow near the center part being connected to a vacuum device through an exhaust gas passage.
