description

This axial piston fan pump adopts integrated temperature sensing variable control valve, which can intelligently reduce displacement when machine is idle or under light digging load, cutting unnecessary power draw. Its cylinder block, pistons and valve plate go through precision surface grinding, maintaining stable volumetric efficiency under frequent load switching between loader bucket and backhoe boom. Compact cast iron pump housing is optimized to fit the narrow engine compartment of backhoe loaders, resisting mud, concrete splatter and continuous vibration caused by trench excavation.
It uses high temperature resistant sealing components, capable of enduring frequent pressure fluctuations during cyclic digging and loading. All finished pumps pass comprehensive bench tests including flow curve detection, pressure holding and leakage inspection before shipment. The mounting flange, oil port layout and spline shaft match original specifications completely, allowing direct replacement without pipe rework or bracket modification.

Application Scenarios

This fan pump adapts to multi-purpose backhoe loader mixed operation:
・Municipal pipeline works：Trench digging, pipe laying and backfilling, alternating digging and loading cycles.
・Residential foundation project：Site clearing, shallow excavation and material handling in compact urban lot.
・Road maintenance：Pothole repair, roadside trenching and gravel backfill on township roads.
・Utility construction：Cable and water line excavation, narrow space operation.
・Small quarry & aggregate yard：Light-duty digging, stockpile tidying and material loading.

advantage

・Built-in temperature-sensing variable valve automatically adjusts pump displacement according to coolant temperature, reduces power loss during idle and light digging work, saving fuel for frequent short-cycle mixed operation.
・Precision ground piston and alloy valve plate assembly offers good wear resistance, coping with muddy site environment and extending service life under alternating front loading and rear excavation.
・Compact cast iron housing is tailored for limited engine compartment of backhoe loader, anti-vibration structure reduces damage risk under impact from trenching.
・High-temperature resistant composite seals maintain stable sealing performance under frequent pressure cycling, lower shaft end leakage risk when machine switches between digging and loading continuously.
・Original matched flange and spline structure simplifies on-site replacement, maintenance technicians can finish installation without extra machining work.
・Strict low-temperature bench test ensures reliable startup and cooling performance in cold seasons, suitable for year-round outdoor construction.

FAQ 

Q1: Which machine does 296-6714 fan pump fit?
A1: It is designed for Caterpillar 414E,416E,422E,428E backhoe loaders. Confirm machine serial number before purchase to avoid wrong part selection.

Q2: What abnormal signs mean the fan pump needs replacement?
A2: Fan fails to speed up as temperature rises, shaft oil seepage, irregular noise under alternating digging/loading, engine overheating during continuous trenching work. Gradual worsening symptoms usually point to internal wear.

Q3: What preparations are needed before installation?
A3: Release residual hydraulic pressure, clean hydraulic tank and pipelines, check hydraulic oil cleanliness and filter condition. After assembly, bleed air from hydraulic circuit and test fan speed regulation under no-load condition.

Q4: The machine still overheats after fan pump replacement, what to inspect?
A4: Check radiator clogging, hydraulic oil grade, control valve function, fan blade deformation, water pump and full engine cooling circuit. Overheating fault may not only come from fan pump failure, complete cooling system inspection is required.

Q5: What is covered under warranty?
A5: 12 months warranty covers manufacturing defects. Damage caused by contaminated oil, improper installation, overload operation and lack of regular maintenance is excluded.
