Used as a shutdown sealing device for vertical diagonal flow pumps, vertical axial flow pumps, and vertical suspended semi submersible vertical turbine pumps

A shutdown sealing device for a vertical pump, comprising an impeller (5), a guide vane body (4), and a shaft sleeve (3). A rubber sealing ring (2) is provided between the impeller (5) and the guide vane body (4), and the rubber sealing ring (2) is sleeved on the shaft sleeve (3). The rubber sealing ring (2) is compressed and fixed on the guide vane body (4) by a half pressure plate (1) and fasteners. The shutdown sealing device used in this vertical pump has a simple structure, good shutdown sealing performance, and easy maintenance. It can be widely used in vertical inclined flow pumps, vertical axial flow pumps, vertical suspended semi submersible vertical turbine pumps, and vertical volute pumps to transport sewage media, with good economic and social benefits.
