OT100 OT200 OT300 Gear Pump | OT100P07D/G11S1 OT100P11D | Oleodinamica Toselli

LIC Hydraulic’s Oleodinamica Toselli (OT) Series gear pumps are the definitive choice for compact, high-efficiency hydraulic applications. Spanning across OT100 (Group 1), OT200 (Group 2), and OT300 (Group 3), these pumps are engineered for performance and durability. We offer 100% Drop-in Interchangeability for configurations like OT100P07D/G11S1, OT100P11D, and OT100P16D. Featuring a high-strength extruded aluminum body and precision-hardened gears, every OT pump undergoes 100% load testing to ensure peak volumetric efficiency in HPU units and industrial machinery.

Key Technical Advantages

• Axial Gap Compensation: Hydrostatic pressure-balanced plates maintain tight internal clearances, ensuring high volumetric efficiency throughout the pump’s service life.

• Lightweight & Heat Dissipating: The aluminum alloy construction provides an excellent power-to-weight ratio and superior heat dissipation for continuous duty cycles.

• Quiet Operation: Precision-ground gear profiles minimize hydraulic ripple and structural vibration, making it ideal for noise-sensitive indoor environments.

• Interchangeable Configurations: Available with a vast array of European and SAE standard flanges and shafts to replace legacy OT or competitive Group 1/2 pumps.

Application Areas

• Micro/Mini Power Packs: Tail lifts, scissor lifts, and compact HPU units.

• Lubrication Circuits: Constant flow supply for heavy-duty industrial gears and bearings.

• Mobile Hydraulics: Steering and auxiliary circuits in specialized agricultural vehicles.

Expert Maintenance Tips

• Verify Rotation: Always match the rotation direction (D for Clockwise, S for Counter-Clockwise) as indicated on the pump body. Reversing the drive on a unidirectional pump will blow the shaft seal instantly.

• Avoid Shaft Misalignment: Use a flexible coupling and ensure precise alignment. Excessive radial or axial loads on the OT100 series will lead to premature bearing failure and internal scoring.

• Fluid Cleanliness: To maintain the 95%+ efficiency rating, maintain hydraulic fluid cleanliness at ISO 4406 19/17/14 or better. Aluminum pumps are susceptible to scoring from metallic debris.
