Tokimec SQP21 Vane Pump | Tokyo Keiki F11-SQP21 | F11-SQP21-21-11

LIC Hydraulic proudly offers the Tokimec (Tokyo Keiki) SQP Series, the industry’s premier “Quiet” hydraulic vane pump. The SQP21 double pump configuration provides versatile flow outputs within a single housing, allowing for complex high/low pressure circuits. The featured model F11-SQP21-21-11-1DC-18 is specifically equipped with Viton (F11) seals, making it compatible with both standard mineral oils and fire-resistant phosphate ester fluids. Engineered for millions of cycles, the SQP series is the ultimate heart for precision injection molding machines and high-end CNC equipment.

Technical Specifications (Quick Reference)

• Sealing: F11 (Viton/FKM Seals) for high-temperature and fire-resistant fluids.

• Frame Sizes: SQP1, SQP2, SQP3, SQP4 (and combinations like SQP21, SQP31).

• Max Pressure: Up to $17.2\text{ MPa}$ ($2500\text{ PSI}$).

• Noise Level: Exceptionally low, ranging from $60\text{ to }75\text{ dB(A)}$ depending on load.

• Interchangeability: 100% Drop-in replacement for Tokyo Keiki OEM units.

Key Technical Advantages

• Ultra-Quiet Pulse Damping: A patented discharge port design minimizes pressure ripples, resulting in the quietest vane pump performance on the market today.

• Cartridge Replacement System: The internal “cartridge kit” can be replaced in minutes without disturbing the pump housing or plumbing, significantly reducing maintenance downtime.

• Hydraulic Balancing: The vane-on-vane and rotor design ensures hydraulic forces are balanced radially, which eliminates bearing side-loading and extends the unit’s lifespan.

• Efficiency & Stability: Maintains high volumetric efficiency throughout its service life, providing stable flow even at peak operating pressures.

Application Areas

• Plastics Machinery: Clamping and injection speed control for injection molding machines.

• Precision Machining: Smooth hydraulic power for CNC grinders and lathe actuators.

• Metal Forming: Multi-stage pressure supply for hydraulic presses and shears.

Expert Maintenance Tips

• Initial Priming: Always fill the pump housing with clean oil through the outlet port before startup to avoid dry-vane friction.

• Monitor Suction Vacuum: Ensure the suction line is not restricted. Excessive vacuum (cavitation) is the leading cause of premature vane tip wear and internal housing “scoring.”

• Oil Cleanliness: Maintain system filtration to at least ISO 4406 18/16/13. Particle contamination is the primary enemy of the precision-ground surfaces within the SQP cartridge kit.
