This is an Instruction Manual and Parts List for Pump Bowl Assemblies manufactured by Worthington (McGraw-Edison Company), applicable to vertical turbine pumps ranging from 10" to 15" UHF (Universal Head Frame) sizes, covering both open and enclosed lineshaft types.

The manual provides comprehensive technical documentation for installation, operation, and maintenance of Worthington UHF vertical turbine pump bowl assemblies. It includes four main sections: Introduction and General Description, Special Service Tools, Maintenance Instructions, and List of Parts. The pump bowls are available in three types (top, intermediate, and discharge) and are designed to operate in wells or sumps with varying head requirements determined by installation specifications. Key components covered include the suction case (bell or open type), impeller with lock collet coupling, discharge case, bearings, and wearing rings. The manual specifies two lineshaft configurations: open line shaft type (with lubrication through the shaft tube) and enclosed line shaft type (with lubrication tube placed over the shaft). Maintenance procedures address disassembly using keyed and snap ring construction, inspection and cleaning protocols, bearing replacement with specified dimensional tolerances, lubrication requirements, and assembly procedures. Special service tools required include an Impeller Lock Collet Driver and Positioning Plug, with dimensional specifications provided for different pump sizes (10", 12", 14HH, and 15"). The document includes detailed parts lists, exploded view diagrams, and nominal dimension tables for reference during ordering and maintenance operations. A critical warning notes that operation exceeding rated capacity, speed, pressure, and temperature specifications may result in personal injury and equipment damage.
