Slurry Pump Rubber Throatbush Interchangeable Pump Rubber Liners
Description:
The throat bushing can form a primary interface between the pump and the mechanical seal. According to the arrangement of the mechanical seal and the type of flush plan applied, such bushings are not always required.
As its definition implies, the primary role of a throat bushing is to provide a restriction between the fluid being pumped by the impeller and the mechanical seal area, so that flow is reduced or controlled. Such a flow restriction can be required in either direction; for instance, the restriction would stop the flow into the seal chamber to avoid particulate contamination of the chamber. When the mechanical seal flush plan uses "processed fluid"-either cooled, filtered or physically different from the pumped media-the flow from the seal chamber into the pump may need to be controlled. Throat bushings must be designed to provide the optimum environment for both the mechanical seal and pump since the fluid flow amount through a concentric annular restriction is proportional to the cube of the clearance and their axial length.
