I. Core Product Information
Product Function: The 14571220C gear pump is a core hydraulic power component for heavy trucks, responsible for providing stable high-pressure hydraulic oil supply for vehicle steering, lifting and braking systems. It features high volumetric efficiency, low leakage and smooth oil output, ensures sensitive response of hydraulic systems under heavy-load, low-speed and continuous working conditions, and is essential for the normal operation of heavy truck hydraulic control systems.
Compatibility Details:
Applicable Vehicles: Mainstream heavy-duty trucks, tractors, dump trucks and engineering vehicles with hydraulic steering/lifting systems
Compatible Hydraulic Systems: Heavy truck power steering hydraulic systems, dump truck hoist hydraulic systems
OE/OEM Number: 14571220C (direct replacement part, perfect interchangeability)
Matching Tip: Standard oil inlet/outlet ports and mounting flange, direct installation without modifying hydraulic pipelines, support hydraulic system pressure matching verification

II. Quality & Performance Guarantee
We adopt batch-certified HT250 cast iron and 20CrMnTi alloy steel, ensuring structural rigidity and wear resistance of core parts. Production processes include precision gear hobbing, CNC machining, carburized quenching, precision assembly, pressure leakage test and anti-rust spraying. Automated production lines yield 100,000 units/year, stably supporting small to large-scale procurement demands.
Three quality tiers for diverse needs: Genuine Grade (meets original factory technical standards for OEM matching), OEM Grade (OE-level hydraulic performance with high cost-effectiveness), High-quality Aftermarket (stable oil supply for regular maintenance use). ISO9001 certified; 100% outgoing inspection covers pressure resistance, volumetric efficiency, leakage performance, low-speed oil output and high-temperature stability. Each unit marked with a unique serial number for full batch and material traceability.
Service life by grade (normal working conditions): Genuine Grade ≥120,000km/3 years, OEM Grade ≥90,000km/2.5 years, Aftermarket ≥60,000km/2 years. Enhanced performance: 30% higher wear resistance (carburized gear shaft), 25% lower oil leakage (enhanced sealing structure), 20% more stable pressure output (precision gear meshing) - ensures reliable hydraulic power supply in harsh working conditions, failure rate reduced by 35% vs conventional gear pumps.

FAQ
1.Can this gear pump be used for both power steering and hoist systems?
Yes, it provides stable 16MPa rated pressure, fully suitable for heavy truck power steering and small/medium tonnage hoist hydraulic systems.
2.What hydraulic oil is recommended for matching use?
We recommend heavy-duty anti-wear hydraulic oil L-HM46, which can effectively reduce gear wear and extend the pump's service life.
3.How to judge the gear pump for oil leakage and pressure loss faults?
Check oil seal and flange connection for obvious oil seepage; detect system working pressure with a pressure gauge - low pressure under rated speed indicates pressure loss.
4.Is the product pre-filled with hydraulic oil for delivery?
No, it is empty of oil when delivered, please fill with matching hydraulic oil before installation and use to avoid dry running damage.
5.Can it adapt to low-temperature cold area working conditions?
Absolutely, the optimized sealing ring and hydraulic oil compatibility design ensure normal startup and oil output at -40℃ without jamming.
