SQP431-30-30-11 Tokyo Keiki Triple Vane Pump | 210 Bar

Product Overview:

Engineered for heavy-duty industrial systems and complex multi-circuit power units, the SQP431-30-30-11-86CCC2-18 high-pressure triple fixed displacement vane pump (covering versatile heavy-load combinations like SQP432-60-30) delivers exceptional flow output and reliability. Built to rigorous Tokyo Keiki (Tokimec) SQP standards, this unit utilizes an advanced intra-vane architecture and precision fluid channels to maintain smooth, low-noise performance even under extreme 210 bar loads. By integrating three independent displacement cartridges onto a single, heavy-duty drive shaft, it provides a highly compact power source that eliminates the need for auxiliary motors or complex splitters. Every single triple pump undergoes rigorous 100% full-load simulated testing for pressure hold, flow consistency, and thermal stability prior to dispatch. Machined to exact industry dimensions, it offers seamless, drop-in interchangeability with original Tokimec SQP series pumps, making it the ultimate upgrade for large-scale injection molding machines and industrial presses.

Key Technical Advantages:

• Space-Saving Triple-Circuit Integration: Driving three independent hydraulic circuits from a single prime mover drastically reduces the footprint of the hydraulic power unit. It streamlines fluid plumbing and eliminates secondary drive motors.

• Intra-Vane Low-Noise Architecture: The specialized intra-vane design ensures vanes are hydraulically balanced against the cam ring. Combined with optimized metering notches, this neutralizes pressure pulsations and provides ultra-low acoustic emissions under peak loads.

• True OEM Interchangeability: Manufactured to precise original factory tolerances, the mounting pilots, flange bolt patterns, and internal cartridge components are 100% interchangeable with Tokimec SQP units, enabling fast, plug-and-play replacements.

• Modular Cartridge Construction: The front, middle, and rear pumping elements are self-contained modular kits. Maintenance personnel can easily extract and replace any specific damaged cartridge in minutes without unbolting the massive main housing from the piping, minimizing costly downtime.

Application Areas:

• Plastic Injection Molding Machinery: Multi-circuit hydraulic setups managing high-flow injection, mold clamping, and ejection stages in high-tonnage injection machines.

• Heavy Metal Forming & Presses: Main and auxiliary power packs for large hydraulic presses, metal shears, and press brakes.

• Steel & Heavy Industrial Equipment: Continuous casting auxiliary units, rolling mill hydraulic stations, and high-volume fluid supply systems.

• Custom Industrial Power Units (HPUs): Stationary power packs requiring coordinated, staged multi-actuator control from a single integrated source.

Expert Maintenance Tips:

• Essential Triple-Chamber Priming: Due to the massive internal volume of heavy-duty triple pumps, all three pump cavities (front, middle, and rear) must be manually filled with clean hydraulic oil through the highest case port before the initial start-up. Dry running is strictly prohibited to prevent immediate, catastrophic scoring of internal plates.

• Large-Volume Suction Cavitation Prevention: Since a single common suction port feeds three large cartridges, intake flow velocity is immense. Ensure the suction line is generously sized, completely airtight, and features a suction strainer capacity of at least 3 times the combined maximum flow to prevent severe cavitation and acoustic noise.

• Stringent Shaft Torque Verification: Always use a heavy-duty flexible coupling and ensure concentricity alignment (TIR) between the motor and pump shafts is within 0.1 mm. Crucially, calculate the combined peak torque when all three pumps operate at maximum pressure simultaneously to ensure it does not exceed the maximum torsional yield limit of the main drive shaft.
