More Information
Summary:Multi-purpose end casing for ring type multi-stage centrifugal pumps adaptable respectively for the side suction end casings and side discharge end casings of horizontal, vertical and dry pit side suction multi-stage ring type centrifugal pumps, are disclosed as having a generally cylindrical body portion having at least four tie rod lugs extending therefrom at generally 90 DEG intervals. Each of the tie rod lugs has an ample adapter bearing surface, and a rabbet fitted surface formed thereon to render the same utilizable with a variety of adapters as may be required in different types of pumps on which the end casings are used. Machined, foot mounting surfaces are provided on at least three sides of the respective side suction end casings and side discharge end casings to enable the ready attachment and detachment of pump casing mounting feet. In addition, bearing housings including provision for pump stuffing box leakage collection and drainage are operatively associated with the respective end casings to provide additional versatility.
