• **Lightweight high-rigidity cast aluminum housing with stress relief treatment, excellent anti-vibration performance**
Cast aluminum housing after stress relief annealing eliminates internal residual stress. It can resist continuous vibration and pressure impact in quarry sites. The housing is not easy to deform, slowing down wear of internal gear and bearing components and extending service life.
• **Optimized flow channel structure and upgraded FKM sealing assembly, good anti-leakage & high temperature resistance**
Optimized internal flow path reduces oil turbulence and cavitation risk. FKM seal set delivers outstanding high-temperature and hydraulic oil aging resistance. It effectively prevents internal and external oil leakage, avoiding premature component wear caused by oil contamination, minimizing unexpected machine downtime.
• **Full hydraulic bench inspection before delivery, high interchangeability for direct plug-and-play replacement**
Each SH460-5 fan pump passes flow, pressure 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.
• **Reliable hydraulic power supply to protect engine and cooling hydraulic system**
This single gear fan pump provides stable pressurized oil for SH460-5 fan motor. It maintains cooling hydraulic system operating normally, preventing engine thermal damage caused by insufficient fan power, ideal replacement for overhaul and daily maintenance of Sumitomo SH460 series excavators.

FAQ 

Q1: Can KJH0337 fan pump be used on SH480-5?
A1: KJH0337 fan pump is designed for SH460-5 / SH460HD-5 and CX460. SH480-5 uses fan pump with different displacement, not interchangeable. Please confirm part number before order.

Q2: What inspection items should be done before installing SH460-5 fan pump?
A2: Check hydraulic oil cleanliness, inspect the fan motor for seizure or heavy internal leakage. A stuck fan motor will cause overload and damage the gear set of the new pump quickly.

Q3: What causes low fan speed after replacing SH460-5 fan pump?
A3: Common causes: insufficient oil supply at pump inlet, air trapped in hydraulic circuit, internal leakage of fan motor or clogged hydraulic filter. Check oil circuit and pressure step by step.

Q4: What is the difference between fan pump and fan motor for SH460-5?
A4: KJH0337 fan pump is the hydraulic power source that generates pressurized oil. The fan motor is the actuator, using pressure oil to rotate cooling fan. They work together as one complete cooling set.

Q5: What maintenance suggestions for SH460-5 fan pump working in mining site?
A5: Replace hydraulic return filter and suction filter on schedule, keep oil cleanliness at NAS8 level or better. Check shaft seal leakage and system pressure reading every 1000 working hours.
