Model ID: DY01-2
The DY01-2 Small Gear Pump is a critical component engineered to ensure the longevity of small-displacement motorcycle engines. Functioning as the heart of the lubrication system, this compact pump utilizes a precision-meshed gear (or trochoid) design. Unlike standard pumps that may suffer from cavitation at high RPMs, the DY01-2 features optimized rotor geometry that ensures smooth, pulse-free oil delivery. This steady flow is essential for maintaining the hydrodynamic film strength required to protect vital components like the camshaft, crankshaft, and cylinder walls from metal-to-metal contact.
Durability is paramount for internal engine components. The internal gears of the DY01-2 are manufactured from high-strength sintered steel, heat-treated to withstand the constant friction and shearing forces of the oil. The housing is precision-machined to tight tolerances, minimizing internal leakage (slippage) and ensuring that oil pressure builds immediately upon startup. Designed for efficiency, this pump minimizes parasitic power loss while delivering the flow rate necessary to cool the engine and flush away contaminants, making it an ideal OEM replacement or upgrade for 50cc to 125cc engines.
