Product Description
Shimadzu SGP Series High-Performance Industrial Hydraulic Gear Pumps
Product Overview: The Shimadzu SGP Series is globally recognized as the high-reliability power core for material handling equipment, particularly forklift systems. This featured selection includes core precision models: the high-pressure SGP2-44L639 and SGP2-52L226, alongside mid-displacement configurations SGP1A36L701 and SGP1A25R382. Engineered with high-strength extruded aluminum bodies and a three-piece reinforced construction, these pumps are designed to maintain elite volumetric efficiency at peak pressures up to 25 MPa. Utilizing advanced axial gap compensation, the SGP series ensures stable flow delivery even under harsh operational environments.
Key Technical Advantages:
Superior Pressure Resilience: Rated for a continuous operating pressure of 21 MPa with peaks reaching 25 MPa (3625 PSI), ensuring reliability under the high-frequency pulse loads of forklift lifting and steering.
High Volumetric Efficiency: Equipped with automatic axial pressure-compensated side plates to minimize internal leakage, maintaining efficiencies over 93% even during high-temperature operations.
100% Plug-and-Play Replacement: Strictly adheres to original Shimadzu OEM specifications, including precision codes like L639, L226, and R382, ensuring identical flange patterns, shaft ends, and port positions.
Quiet & Smooth Operation: Precision-ground 12-tooth gear profiles drastically reduce mechanical noise and pressure ripples, protecting downstream sensitive valve components.
Vibration Resistance: Reinforced sliding bearing construction combined with an optimized housing design effectively absorbs system shocks, extending total service life.
Detailed Models & Parameters:
Core Series: Shimadzu SGP1 & SGP2 Performance Series.
