This hydraulic pump adopts external meshing gear pump design, manufactured by precision gear grinding and high-precision matching process. The floating pressure balance side plate structure automatically compensates end clearance, effectively reducing internal leakage and maintaining high volumetric efficiency under long-term high-pressure operation. The integral aluminum alloy shell features light weight, high rigidity and good heat dissipation performance. Optimized bearing and pre-pressure lubrication structure enhances impact load resistance and extends service life. Standard SAE installation flange and oil port specification, accurate overall dimension and strong interchangeability, easy installation and direct replacement, adapting to heavy-load and high-frequency working conditions.
Professional OEM part number 3349111189, compatible with Parker and SANY reach stacker with strong interchangeability.
High-precision gear grinding process ensures stable flow output, low pulsation and smooth hydraulic transmission.
