This is a technical engineering drawing for a vertical canned turbine pump diffuser manufactured by Worthington Corporation. The document is marked "FOR INFORMATION ONLY" and appears to be a pattern shop drawing referenced as RW-13834.

The drawing provides detailed specifications for a diffuser assembly designed for use in vertical turbine pump applications. Key specifications include material composition of ASTM Spec. A 27-60 Grade CE-30 for the main body and ASTM Spec. A 283-60 Grade "B" for steel plates. The design incorporates multiple drilling specifications, including 41/64-inch diameter holes equally spaced on 1.5-inch bolt circle diameter (B.C.D.), and 1 5/8-inch diameter holes for straddle straps. The diffuser features torch-cut flat surfaces as noted on the engineering drawing. Construction details indicate welded assembly with specific measurements and tolerances throughout. The drawing includes both plan and elevation views with comprehensive dimensional annotations, cross-sectional details, and assembly instructions for manufacturing purposes. This technical documentation would be used for procurement or manufacturing of replacement or new diffuser components for vertical turbine pump systems in industrial applications.
