Product Description
Hydraulic Fan Pump 173-3420 for Caterpillar 345B & 345C Excavators
Product Overview: The 173-3420 (1733420) Hydraulic Fan Pump is the essential power unit for maintaining optimal operating temperatures in Caterpillar 345B and 345C series heavy-duty excavators. As a critical component of the cooling system, this pump drives the hydraulic fan motor, regulating cooling intensity based on real-time engine thermal loads. Whether in mining or heavy earthmoving applications, the 173-3420 provides exceptionally stable pressure output, effectively preventing system overheating and extending the service life of all hydraulic components across the machine.
Key Technical Advantages:
OEM-Grade Compatibility: Manufactured to strict Caterpillar (CAT) standards as a direct replacement for part number 173-3420, ensuring zero-gap seamless integration with 345B/345C hydraulic circuits.
Heavy-Duty Anti-Pulsation Design: Features a reinforced housing and bearing structure capable of withstanding high-frequency hydraulic load fluctuations and shocks—ideal for 24/7 excavator operations in harsh outdoor environments.
Efficient Thermal Management: Precision volumetric regulation ensures the fan drive system receives sufficient starting pressure at low speeds while maintaining constant cooling flow at high speeds.
Optimized Fuel Economy: Advanced internal leakage compensation (volumetric efficiency >93%) reduces parasitic power loss from the cooling system, helping the machine achieve better fuel efficiency.
Target Applications: Cooling systems for Caterpillar 345B, 345B L, 345B Series II, 345C, and 345C L excavators.
