Product Details
The 14571220C is a precision-engineered high-pressure gear hydraulic pump manufactured to strict Sinotruk OEM specifications, serving as the power core of the tipping and lifting system on HOWO dump trucks and tractor heads. Operating under continuous heavy load, high oil temperature and severe vibration typical of commercial haulage, this fixed-displacement external gear pump delivers stable high-pressure oil flow to drive the dump cylinder and auxiliary hydraulic systems reliably. Built with a high-strength aluminum alloy housing and precision-machined hardened steel gears, the 14571220C maintains high volumetric efficiency and low noise across its full speed range. As a factory-direct genuine Sinotruk component, every pump is 100% inspected before shipment, ensuring direct-fit installation with original mounting dimensions, spline shafts and port configurations.

Features
High-Pressure Lifting Performance: Engineered specifically for the HOWO dump truck tipping system, the 14571220C delivers stable, high-pressure oil flow that lifts and lowers heavy payloads smoothly and repeatedly without pressure drop under maximum load.
Precision-Machined Gears, High Volumetric Efficiency: Hardened alloy steel gears with precision-ground profiles maintain tight internal clearances, delivering high volumetric efficiency and consistent flow output — minimizing energy loss and heat generation in continuous duty cycles.
Heavy-Duty Durability: High-strength aluminum alloy housing combined with hardened gears and heavy-duty shaft bearings ensures reliable operation under high pressure, high temperature and sustained vibration, giving the pump an extended service life in demanding haulage conditions.
100% OEM Direct-Fit: Manufactured to original Sinotruk specifications, the pump matches the factory mounting flange, spline shaft and port dimensions exactly. Direct drop-in replacement for the original unit, saving mechanics downtime during hydraulic system repairs.
Low Noise & Stable Operation: Precision gear meshing and balanced rotor design keep noise and pulsation low, protecting the hydraulic system from shock loads and ensuring a quieter cab and working environment.
Strict Quality Control: Every pump undergoes 100% factory inspection, including pressure testing, flow testing and leak testing before shipment, ensuring each unit meets OEM performance standards.
