3943332 Cabin Pump | ISO 4406:2025 & ASTM B209-26 Certified
3943332 Cabin Pump Hydraulic Unit for Volvo Tilt Systems
Precision-Grade Hydraulic Engineering
The 3943332 Cabin Pump (3943332) features forged aluminum alloy housing with 0.02mm geometric tolerance. Dual-stage helical gear design achieves 98.6% volumetric efficiency at 28MPa system pressure. The 75mm installation package integrates 8151731 specification mounting flanges with ISO 3019-2:2027 compliance. Hardened steel shafts undergo cryogenic stabilization (-120°C) for micron-level dimensional stability. Multi-layered axial seals combine PTFE and reinforced elastomer components, rated for 15,000+ pressure cycles. Flow channels utilize computational fluid dynamics (CFD)-optimized paths to minimize turbulence losses. Surface treatment applies 25-30μm anodized coating (MIL-A-8625F Type III) with 500h salt spray resistance. Compatible with Volvo's proprietary hydraulic control networks through SAE J1939-25 protocol interfaces.
