Key Technical Advantages
1. Pressure-Balanced Design – High Efficiency
All GearMe series pumps feature pressure-balanced design, maintaining high volumetric and overall efficiency across the full pressure range. Pressure-balanced bearings deliver optimal performance throughout the operating range.
2. High-Strength Extruded Aluminum – Lightweight Construction
High-strength extruded aluminum bodies with aluminum covers and flanges deliver maximum strength with minimum weight. The TFP0NN series weighs as little as 0.40 kg.
3. Teflon-Coated Bushings – Extended Service Life
SKP2NN series features Teflon-coated bushings that extend service life under extreme temperature, pressure, and speed conditions.
4. Broad Speed & Temperature Operating Range
Group 1 supports up to 4,000 rpm, Group 0 up to 8,000 rpm. Operating temperature range from -20°C to +80°C ensures stable flow characteristics from cold start to high-speed continuous duty.
5. Multi-Pump Combination Capability
Supports Group 1, 2, and 3 multi-stage combinations for flexible system expansion.

Expert Maintenance Tips
1. Fluid Cleanliness Control
Maintain system fluid cleanliness to ISO 4406 19/17/14 or better. Install a 10–25 μm absolute filtration filter upstream of the inlet port to prevent particle contamination from damaging precision gear pairs and bearings.
2. Inlet Line Requirements
Keep suction lines short and straight with adequate diameter—not less than the port size. Recommended suction line flow velocity: ≤1.5 m/s to prevent cavitation from excessive inlet resistance. Inlet pressure must be maintained between 0.8–2.0 bar (absolute) .
3. Coupling Alignment Precision
Ensure pump shaft-to-drive shaft coaxiality deviation ≤0.05 mm and angular deviation ≤0.5° during installation. Flexible couplings are strongly recommended. If the drive involves sprockets or V-belt pulleys, an independent outboard bearing MUST be installed to protect the pump shaft.
4. First-Start Priming Procedure
Before initial startup, prime the pump by bleeding air through the drain port or a loosened outlet fitting. Perform 2–3 jog starts with the outlet open (no load) until oil fills the pump cavity without air bubbles, then connect the load circuit for full operation.
5. Viscosity & Temperature Monitoring
Recommended operating viscosity: 12–100 cSt. During cold starts when viscosity exceeds the recommended range, ensure adequate suction conditions or preheat the fluid. Operating temperature range: -20°C to +80°C.
6. Rotation Direction Confirmation
“R” indicates clockwise rotation; “L” indicates counterclockwise. Always verify that the drive motor/engine rotation matches the pump before installation.
