Product Description
SDY Series High-Performance Double/Tandem Hydraulic Gear Pumps
Product Overview: The SDY Series Double Pump stands as a highly efficient power core for modern mobile hydraulic systems. This featured selection includes core precision models: the specialized SDY1A-3612L573 and the standard SDY1-363.5R525. Engineered with a unique multi-stage integrated design, these pumps synchronize two independent pump sections via a single drive shaft, allowing for separate oil delivery to primary and auxiliary circuits (such as steering or pilot systems). Featuring high-strength extruded aluminum bodies and precision axial compensation, the SDY series delivers exceptional performance at pressures up to 25 MPa, making it the premier choice for forklifts, mini-excavators, and agricultural machinery.
Key Technical Advantages:
Efficient Dual-Circuit Integration: The SDY1/SDY1A tandem design provides dual flow outputs within a compact unit, significantly reducing external piping and optimizing installation space.
Superior Pressure Resilience: Rated for a continuous operating pressure of 20 MPa with peaks reaching 25 MPa (3625 PSI), ensuring reliability under heavy-duty duty cycles.
High Volumetric Efficiency: Equipped with automatic axial pressure-compensated side plates to minimize internal leakage, maintaining efficiencies over 93% even under extreme operational environments.
100% Plug-and-Play Replacement: Strictly adheres to original OEM specifications, including L573 (CCW/Specific interface) and R525 (CW/Specific interface) codes, ensuring identical flange patterns, shafts, and port positions.
Quiet & Smooth Operation: Optimized gear profiles drastically reduce pressure ripples during operation, protecting downstream sensitive valves.
Detailed Models & Parameters:
Core Series: SDY & SDY1A Tandem Series.
Model Keywords: SDY1A-3612L573, SDY1-363.5R525.
