Overview
This Pum lantern cast is a precision-cast pump‑motor connector designed to mount Type 132 motors to 180/230 series pump bodies. Produced by precision casting and multi‑process machining, it meets ISO 2768-mK general tolerances and provides defined dimensional, geometric and surface characteristics required in mechanical transmission assemblies.

1. Core Basic Product Information

• Adapted specifications: compatible with 180/230 series pump bodies and Type 132 motors.
• Processing standard: ISO 2768‑mK general tolerances; machining processes include cutting, chipping and forming.
• Angular tolerance: controlled machining of key angles to ensure correct fit for special-shaped structures.

2. Key Dimensional and Precision Requirements
The casting incorporates multiple bore diameters and axial dimensions with strict tolerance bands to match motor and pump assembly/clamping points. It includes core assembly bores, secondary precision fit bores, large-specification assembly bores and auxiliary bores, plus precise axial dimensions for motor shaft end positioning and defined angles for special assembly positions. Small local structures and distributed small bores enable weight reduction and auxiliary fixation.

3. Geometric Tolerance Requirements
Defined geometric tolerances control coaxiality, perpendicularity, positional accuracy and parallelism to limit machining deformation and ensure assembly alignment. Benchmark-based tolerance definitions apply to core parts and critical local structures; non-core positions receive basic geometric protection. Refined angular control secures fit of special-shaped features.

4. Surface Processing and Roughness Requirements
Surfaces are assigned differentiated Ra grades according to function. Key mating surfaces receive fine cutting to achieve tight fits and smooth torque transmission; auxiliary and special-shaped surfaces use conventional precision processing to balance performance and cost. Chamfering is applied to eliminate sharp edges and reduce stress concentration.

5. Thread and Fastener Adaptability
The component integrates multiple standard threaded holes sized for universal fasteners to avoid custom hardware. Main threaded holes accept large-spec fasteners for primary fixation; secondary threaded holes are evenly distributed for assembly stability; small threaded holes secure peripheral auxiliary parts, simplifying maintenance.

6. Product Process and Quality Characteristics

• Precision casting base: casting produced to avoid sand holes, air pockets and cracks, delivering high base density and strength for pump transmission loads.
• Multi-process composite machining: combined cutting, chipping and forming achieve target dimensions, geometric tolerances and surface roughness with controllable precision.
• Standardized tolerance design: full compliance with ISO 2768-mK for dimensional consistency and interchangeability with Type 132 motors and 180/230 pump series.
• Humanized structural design: chamfered edges, evenly distributed threaded holes and lightweight bore arrangements facilitate assembly, safety and weight reduction.
• Full-dimensional quality control: inspection of key dimensions, geometric tolerances and surface roughness to ensure conformity with drawings and stable outgoing quality.

7. Product Application and Adaptation Scenarios
Intended as the connection and torque‑transmission element between Type 132 motors and 180/230 pump bodies, this lantern casting is suitable for industrial pumps, hydraulic pumps and water supply pumps. Typical sectors include metallurgy, chemical industry, municipal water supply and mechanical manufacturing; functions include positioning, connection and torque transfer between motor and pump body.

Conclusion
Pum lantern cast engineered for precision manufacturing and standardized tolerances to ensure reliable assembly fit and consistent performance in industrial pump transmission systems.
