Structures Of Non-Positive Displacement Pumps
(AREA)
Abstract
Sealing for liquids, characterized by consisting of a ring integral with the axis of the centrifugal pump and another ring attached with a float held by an elastic membrane to the pump body, so that when the pump is stopped the liquid that carries inside makes the float rise, which presses one ring against the other ensuring a perfect closure, but when the pump works the depression created by its fins decreases the liquid level, with which the float goes down and they separate both rings.
