XCMG QY130K Gear Pump 803000320
XCMG 803000320 is a gear-pump reference for compatible QY130K crane hydraulic circuits. Rotation, displacement and mechanical interfaces must match to protect the pump and driven circuit.
Identification and Matching
XCMG part 803000320
Manufacturer and complete pump code
Rotation and input shaft
Port size and orientation
Mounting flange and circuit function
Application and Service Scenarios
Use after confirmed gear or bearing wear, leakage, noise or insufficient flow. Suction restriction, aeration, relief settings and downstream leakage may produce similar symptoms.
Inspection and Installation
Flush contamination, prime the inlet, confirm rotation and align the coupling. Start unloaded and monitor flow, pressure, noise, temperature and seals.
Frequently Asked Questions
Can a same-size gear pump substitute?
Only when displacement, rotation and interfaces match.
What causes whining?
Aeration, suction restriction or wear may be responsible.
Is clean priming required?
Yes, to prevent dry-start damage.
Export Packing
Ports and shaft are protected and the pump is fixed in a reinforced crate.
