Abstract:
A centrifugal liquid pump includes an impeller and a hub for the impeller, whereby gases entrained in the liquid are separated from the liquid and collect near the hub by centripetal action. A shaft is connected to the hub for rotating the impeller, and a passageway extends axially through the shaft. A gas entry is provided near the hub in communication with the passageway. An air pump is provided at an opposite end of the shaft for evacuating the separated gases collected near the hub. The air pump is independent of and remote from the impeller and is in communication with the passageway extending axially through the shaft.
