CAT365C Fan Pump for Caterpillar 65-ton large heavy-duty excavator spare parts

Short Description:

The CAT307C main hydraulic pump is an original high-precision variable piston pump tailored for Caterpillar 7-ton small excavator hydraulic system. Precisely calibrated to match the engine power output and torque response of CAT307C mini excavator, it acts as the core hydraulic power source of the whole machine. The pump converts mechanical rotation energy into stable high-pressure hydraulic power, providing accurate flow supply for boom, arm, bucket, traveling and slewing hydraulic mechanisms. Optimized for urban renovation, landscaping, indoor demolition, narrow-site construction and frequent light-load switching working conditions, it features sensitive operation response, stable pressure output, low noise and low heat generation, ensuring smooth, efficient and reliable operation of CAT307C excavator in various compact and complex construction scenarios.

description

The CAT365C fan pump adopts high-precision fixed/displacement variable hydraulic pump structure, equipped with built-in pressure regulating valve, flow control valve and overload protection components. It follows the original Caterpillar cooling system matching standards, which can dynamically adjust fan speed according to equipment load and ambient temperature changes, ensuring accurate heat dissipation balance. The pump body is integrally cast with high-strength alloy materials; internal precision matching pairs undergo ultra-fine grinding and surface hardening treatment, with low friction resistance and excellent wear resistance. All finished fan pumps pass strict factory pressure testing, flow calibration and high-temperature durability tests. Compared with ordinary universal replacement pumps, the genuine CAT365C fan pump features higher system matching accuracy, more stable speed regulation, no stalling or jitter, and effectively solves common faults such as poor heat dissipation, high system temperature, fan jitter and abnormal noise caused by mismatched parameters.

advantages

• Adopts exclusive original calibration for CAT365C cooling system, with perfect hydraulic matching, ensuring synchronous linkage between fan speed and system heat load.
• Intelligent adaptive speed regulation technology automatically adjusts fan operation status to avoid ineffective high-speed operation and reduce equipment energy consumption.
• High-precision wear-resistant internal components effectively reduce internal leakage, maintaining stable hydraulic output under long-term high-temperature operation.
• Built-in multi-group pressure protection structures to avoid pressure impact damage and extend the service life of the cooling system.
• Excellent high-temperature resistance and heat stability, no heat decay or speed stall in harsh high-temperature working environments.
• Upgraded sealing system prevents hydraulic oil leakage, adapting to long-term high-vibration mine working conditions.
• Standard original installation dimensions support non-destructive direct replacement, saving maintenance time and quickly restoring equipment heat dissipation performance.

maintenance & replacement tips

• Regularly inspect the pump body, oil port joints and connecting pipelines to eliminate oil leakage risks caused by long-term high vibration and heavy-load operation.
• Replace hydraulic oil and filter elements on schedule to prevent dust and particle impurities from scratching internal precision components and causing flow insufficiency.
• Use qualified anti-high-temperature hydraulic oil to avoid oil deterioration leading to stuck valves, speed regulation failure and poor heat dissipation.
• Regularly detect the output pressure and operating state of the fan pump to ensure the cooling system works within a constant temperature range.
• Avoid long-term over-pressure operation and frequent impact load to prevent premature fatigue damage of internal components.
• In case of fan speed instability, equipment high temperature, abnormal noise and oil leakage faults, replace the genuine CAT365C fan pump in time to restore normal heat dissipation function of the excavator.
