Product Description
Shimadzu SGP1 Series High-Performance Forklift Hydraulic Gear Pumps
Product Overview: The Shimadzu SGP1 Series serves as the vital power core for global material handling hydraulic systems. This featured selection includes precision models optimized for demanding lifting cycles: SGP1A31.9L438, SGP1A32A1H2-R, and SGP1A20R330. Engineered with high-strength extruded aluminum bodies and advanced pressure-compensated bushing technology, these pumps are specifically designed to meet the rigorous demands of 1.5-3.5 ton forklifts for high pressure (up to 25 MPa) and long-term operational stability under heavy loads.
Key Technical Advantages:
100% Plug-and-Play Replacement: Strictly adheres to original Shimadzu OEM specifications. Suffix codes like L438 and R330 guarantee that mounting flanges (pilot diameter), shaft splines, and port positions are 100% identical for a seamless installation.
Superior Pressure Resilience: Rated for a continuous operating pressure of 21 MPa (210 Bar) with peaks reaching 25 MPa (3625 PSI), built to absorb intense load shocks typical of forklift lifting cycles.
High Volumetric Efficiency: Featuring automatic axial gap-compensated wear plates to minimize internal leakage, maintaining efficiencies over 93% even under high-temperature and variable-speed conditions, preventing oil overheating.
Compact & Lightweight Design: The optimized aluminum alloy construction reduces overall weight and provides superior thermal management, ideal for high-intensity work within tight engine compartments.
Quiet & Smooth Operation: Precision-ground gear sets drastically reduce mechanical noise and flow ripples, protecting downstream control valves and enhancing operator comfort.
