・307-3069 variable piston hydraulic fan pump, OEM replacement, perfectly matched with supporting fan motor for CAT432F backhoe loader cooling system
307-3069 hydraulic fan pump is custom fitted for CAT432F backhoe loader cooling circuit. It converts mechanical power into hydraulic energy and delivers regulated pressurized oil to fan motor. Stable flow output ensures fan can adjust speed flexibly under continuous earthmoving and loading operation, preventing engine overheating.
・High-rigidity cast iron housing with stress relief treatment, excellent anti-vibration and pressure impact resistance
Cast iron housing after stress relief annealing eliminates internal residual stress. It can resist continuous vibration and cyclic pressure impact on construction sites. The housing is not easy to deform, slowing down wear of internal piston, valve plate and bearing components and extending service life.
・Full hydraulic bench inspection before delivery, high interchangeability for direct plug-and-play replacement
Each 307-3069 fan pump passes pressure, flow, variable performance and durability hydraulic bench test. All mounting dimensions, port positions and spline shaft fully match OEM specifications. Direct installation without modification, shortening equipment downtime and cutting maintenance cost.

FAQ 

Q1: What machine models does 307-3069 fan pump fit?
A1: Mainly for CAT432F backhoe loader, also interchangeable for CAT420F,430F,444F F-series backhoe loaders. Confirm part number before purchase.

Q2: What is the core function of this variable piston fan pump?
A2: It changes output flow automatically according to engine temperature, adjusting fan speed to keep engine operating temperature within the normal range and reduce power consumption.

Q3: What are the symptoms of internal wear of this fan pump?
A3: System pressure drops under heavy load, fan speed cannot rise, engine temperature rises gradually, and obvious internal leakage occurs.

Q4: What should we pay attention to during pump installation?
A4: Clean the hydraulic tank and pipeline thoroughly, replace hydraulic oil and filter. Bleed air after assembly to avoid cavitation damage to pump internal components.

Q5: How to reduce cavitation risk of the fan pump?
A5: Ensure sufficient oil supply, prevent oil filter blockage, avoid low oil level, and use hydraulic oil with proper viscosity grade.
