・High strength forged pump body. Made of wear-resistant alloy material, strong compression and deformation resistance. Not easy to leak oil under long-time high pressure and high temperature, guarantees stable hydraulic output.
・Accurate temperature-sensing automatic speed regulation. Compatible with original machine control logic. Fan speed changes along with water temperature and hydraulic oil temperature. Reduces idle power consumption and saves fuel.
・Harsh working condition adaptability. Optimized internal oil circuit and sealing assembly. Adapt to high temperature, heavy load and dusty construction sites, reduce premature wear and early failure.
・Strict full inspection before shipment. Each pump is tested for pressure resistance, flow stability and static sealing. Smooth running, low noise, consistent batch performance.
・Reliable heat dissipation performance. Fast response for cooling adjustment. Solves overheating alarm, high-temperature power reduction during heavy loading.
・Direct replacement with good cost performance. Installation dimensions and interfaces fully match OE specs. No pipeline modification required. Ideal aftermarket spare part for machine overhaul and routine maintenance.

FAQ 

Q1: Can this fan pump fit all CAT excavators?
A1: No. The 564-9803/564-9801 fan pump is specially for CAT345GC and CAT349GC excavators. Different CAT models have different pump displacement and mounting interfaces. Please verify machine model and original part number before ordering. Wrong part will lead to insufficient cooling, engine overheating and related faults.

Q2: What tests are performed before shipment?
A2: All fan pumps are 100% fully inspected before delivery, including pressure resistance test, flow stability test, high-temperature sealing test and no-load running test. Products can only be packed after all indicators meet standards.

Q3: What is the warranty scope and non-warranty conditions?
A3: 12-month warranty under standard installation and normal operation. Warranty excludes damage caused by improper installation, contaminated hydraulic oil, blocked oil circuit, lack of maintenance, man-made collision or other host system failures.

Q4: Does it need debugging after installation?
A4: The pump is pre-calibrated before leaving factory and can be installed directly. If temperature deviation or slow fan response occurs after replacement, clear fault codes and perform simple hydraulic matching learning.

Q5: What preparations are needed before installation?
A5: Thoroughly clean hydraulic oil circuit to remove dirt and metal debris; replace hydraulic filter and check hydraulic oil cleanliness. Inspect fan motor and pipeline sealing. Keep installation area clean to prevent dust entering hydraulic circuit and wearing new pump.
