SQP43-60-30 Tokimec Triple Vane Pump 189+95 cm³/r 17.5 MPa

Product Overview:

The SQP21, SQP31, SQP32, SQP41, SQP42, SQP43 series (including SQP43-60-30-86AA-18-S116 and SQP432-50-25-12VQ-86DAB) are Tokyo Keiki (formerly Tokimec) low-noise fixed-displacement triple vane pumps. These units combine three independent cartridges in a single body with a common inlet and three separate outlets, enabling compact multi-circuit or high-low pressure configurations. Manufactured to exact original geometric tolerances, they offer true drop-in interchangeability—matching mounting flanges, shaft ends and port centers precisely—so they can replace OEM units without system modifications. Every pump undergoes 100% simulated duty-cycle testing to verify volumetric efficiency, pressure retention and noise performance. Hydraulic balancing of the vanes combined with precision-machined cam rings and rotors delivers low pulsation, quiet operation and extended service life, making them ideal for machine tools, injection molding machines and industrial hydraulic systems.

Key Technical Advantages:

1. True drop-in interchangeability and precision machining: Exact match to Tokyo Keiki original mounting dimensions, shaft ends and port centers enables direct OEM replacement without system changes, minimizing downtime and modification costs. High-precision cam ring, rotor and vane processing ensures consistent performance.
2. High volumetric efficiency with hydraulic balancing: Pressure-balanced vanes significantly reduce cam-ring wear, delivering high volumetric efficiency and stable triple independent outputs for multi-circuit requirements.
3. Low-noise and low-pulsation design: Optimized inlet geometry and vane configuration minimize oil turbulence and flow ripple, resulting in quiet operation suitable for noise-sensitive machine-tool environments.
4. Long-life bearings and easy maintenance: Quality bearings and wear-resistant materials extend service life; independent replaceable rotating element (cartridge) design allows rapid on-site maintenance, reducing total cost of ownership.

Application Areas:

Hydraulic systems for machine tools and machining centers, injection molding and die-casting machines, plastic machinery, metallurgical equipment, industrial hydraulic power units and multi-circuit fixed installations.

Expert Maintenance Tips:

1. Ensure precise shaft alignment during installation (flexible coupling recommended) to avoid additional radial or axial loads that accelerate bearing wear.
2. Fully prime the pump and verify a leak-free, air-free suction line before initial start-up; use clean anti-wear hydraulic oil of high cleanliness class.
3. Maintain suction and return filters regularly to prevent particle ingress that can score vanes and the cam ring; keep operating oil temperature within recommended range.
4. When replacing the rotating element, work in a clean environment and tighten housing bolts to original torque values; for long-term storage, run the pump briefly every 3–6 months to prevent internal corrosion.
