For 9521A031H 398-1498 3981498 Fuel Pump Perkins CAT 320D C7.1 Excavator Engine Parts

Specification

Description

This fuel pump corresponds to part numbers 9521A031H, 398-1498 and 3981498, specially matched for 320D and C7.1 series excavator engines, serving as the core fuel supply spare part of construction machinery engines.
It adopts split precision cast aluminum housing and high-strength alloy internal components, equipped with six fuel outlet connectors, integrated speed regulating spring, electronic pressure regulating assembly, and inlet & outlet protective joints. Each unit undergoes professional bench fuel calibration before delivery with brand-new matching seals, perfectly meeting diesel supply requirements under heavy-duty construction working conditions.

Advantage

Precisely machined housing: Integrally formed cast aluminum shell with anti-vibration and anti-corrosion performance, avoiding cracking and oil leakage under high & low temperature construction site environments.
Complete new sealing kits: Multi-layer oil seals for fuel ports and pump joints to eliminate oil leakage and pressure loss failures.
OEM-level fuel calibration: Fuel injection pressure and delivery volume calibrated by professional equipment, no repeated adjustment needed after replacement.
Multi-part-number compatibility: Compatible with three part numbers including 9521A031H, 398-1498 and 3981498, featuring strong interchangeability for replacement.
Integrated assembly design: Combined speed control, pressure regulation and fuel supply units for easy installation & disassembly, cutting maintenance time cost.
Heavy-duty durable structure: Wear-resistant alloy plungers and camshaft inside, with low abrasion during long-time continuous operation.

Performance

Stable fuel supply: Constant injection pressure output without obvious pressure fluctuation at idle speed, heavy climbing load and high RPM, delivering smooth power without stalling.
Excellent fuel atomization: Precise plunger stroke control ensures full diesel atomization, more sufficient combustion, lower fuel consumption and less particulate exhaust emission.
Sensitive pressure adjustment: Quick response of electronic pressure regulating assembly, automatically adjusting fuel supply instantly under load change to prevent power drop and black smoke.
Wide temperature adaptability: Stable operation between -25℃ and 65℃, smooth cold start fuel supply in winter and no vapor lock or pressure loss under high temperature in summer.
Long-lasting leak-proof sealing: Diesel-resistant rubber seals resist aging and hardening after long-term diesel immersion, no oil seepage or speed drop caused by pressure loss in long service life.
Shock & vibration resistance: Internal transmission structure with buffer limit blocks, preventing internal parts displacement and damage under bumpy excavator operation to extend overall service life.
