Pump Performance — Arpit Bhatt

Reported case: 150 m3/h; 38 to 45 m head after restoring radial wear-ring clearance from 0.9 to 0.3 mm.

CAD: dimensioned interface study, not a complete hydraulic pump design. All geometry except the reported radial clearances is an explicit teaching assumption. Three solids: rotor land, stationary wear ring and simplified housing seat. Nominal housing fit only; no retention or interference specification.

STEP files are exchange models importable into mainstream CAD software. STL files are mesh geometry in mm. The SVG clearance drawing uses an expanded radial scale. CSV contains a fixed-pressure thin-annulus orifice sensitivity model, not a head-performance prediction or measured leakage.
