AstralPool Pump Impeller / Closed Wheel (120.5mm OD)

Highly detailed 3D CAD model of a closed centrifugal impeller for AstralPool water pumps (commonly used in swimming pool and SPA filtration systems). Original impellers often fail, crack, or dissolve over time due to cavitation and constant exposure to aggressive pool chemicals (chlorine, salt). This model is a perfect, cost-effective solution to repair your expensive pool pump without waiting weeks for replacement parts! Dimensions (Check before printing): Outer Diameter (OD): 120.5 mm Intake/Eye Inner Diameter: 87.5 mm Total Height: 91.3 mm Special Feature (.STEP File Included!): A perfect, tight fit onto the motor shaft is crucial to prevent vibrations. A .STEP (.stp) CAD file is included alongside the STL/3MF files! This allows you to easily import the model into your favorite CAD software and fine-tune the center shaft hole tolerance to match your specific 3D printer and filament shrinkage. ⚠️ ENGINEERING & MATERIAL WARNING: Pool pumps operate 24/7 pushing chemically treated water. Standard filaments (PLA, basic PETG, ABS) may degrade, delaminate, or fail. ✅ FIELD-TESTED RECOMMENDATION: The author highly recommends using chemically resistant, high-temp engineering composites like QIDI PPA-CF (PAHT). This specific material has been practically tested in demanding pump applications and performs flawlessly! The part must be printed solid (100% infill). Post-print static balancing is recommended before installation. 🎁 GET 20% OFF YOUR NEXT PURCHASE! 🎁 I love seeing your prints! Post a picture of your print (a "Make") on this page.
