📐 Crescent Machining (Hardened Cast Iron Crescent Sector, Viscous Volumetric Slip <4.0%)

Internal Gear Pump Crescent Clearance Calculator

Model radial gap clearances ($0.08 ext{ to }0.18 ext{ mm}$) between the stationary crescent sector, idler gear tips, and outer rotor teeth: minimize internal slip flow under high discharge backpressure ($18 ext{ bar}$), maintain volumetric efficiency $>96%$, and pumping accuracy yields.
