Product Description
LIC Hydraulic proudly offers the Oleodinamica OT Series, a premium range of aluminum gear pumps known for their high efficiency and modular versatility. Following European standard mounting patterns, the OT100, OT200, and OT300 series are the heart of countless mobile and industrial hydraulic systems. Whether you need a compact OT100P07 for a micro power pack or a high-capacity OT300P22 for heavy-duty lifting, these pumps deliver consistent flow and pressure. With precision-ground gears and axial pressure compensation, the OT series ensures quiet operation and long-term reliability.
Technical Specifications (Quick Reference)
Groups: Group 1 (OT100), Group 2 (OT200), Group 3 (OT300).
Displacement Range: $0.7\text{cc to }73\text{cc/rev}$.
Max Continuous Pressure: Up to $250\text{ bar}$ ($3600\text{ PSI}$).
Shaft & Flange: Standard European Tapered shafts, Splined shafts, and SAE options available.
Key Technical Advantages
Axial Clearance Balancing: Floating bushings automatically adjust to system pressure, minimizing internal leakage and maximizing volumetric efficiency even at high temperatures.
Modular Tandem Capability: The OT series allows for easy assembly of multiple pump stages (Tandem Pumps), enabling one drive source to power several independent hydraulic circuits.
Low Noise Profile: Advanced gear tooth geometry and high-precision finish reduce fluid-borne noise, ideal for indoor industrial applications.
Lightweight Durability: The high-tensile extruded aluminum body provides excellent heat dissipation and a high power-to-weight ratio.
Application Areas
Mobile Hydraulics: Steering and auxiliary circuits for tractors, excavators, and telehandlers.
Material Handling: Primary lift pumps for electric and diesel forklifts.
Industrial HPUs: Powering hydraulic presses, compactors, and automated manufacturing lines.
Expert Maintenance Tips
Verify Rotation: Always match the pump rotation (Clockwise D or Counter-Clockwise S) to your drive unit. Reversing the rotation on a standard OT pump will result in immediate shaft seal failure.
Prevent Cavitation: For larger displacements like the OT200P28 or OT300P22, ensure the suction line is unrestricted and air-tight. Cavitation can score the aluminum housing, leading to rapid loss of pressure.
Filtration Integrity: Maintain oil cleanliness at or above ISO 4406 18/16/13. Gear pumps are sensitive to hard particles which can wear down the pressure-balanced side plates.
