Tokyo Keiki Type SQP Series Double Vane Pump | SQP21, SQP431, SQP432

Tokyo Keiki Type SQP Series High-Performance Low Noise Double Vane Pumps

Product Overview: The SQP Series is widely recognized as the industry benchmark for “Extreme Quietness” in vane pumps. These fixed displacement pumps are specifically developed to meet modern workshop demands for low-noise environments, spanning single, double (e.g., SQP21), and even triple pumps (e.g., SQP431, SQP432). This featured range includes core models: SQP-21-21-11-10-C, SQP-431-50-38-8-86CC, and SQP-432-60-35-14-86CC. Utilizing a unique pressure-balanced construction and a modular cartridge combination system, the SQP series enables a single drive shaft to power multiple circuits with different flow rates—serving as the ideal power core for large-scale injection molding and die-casting machines.

Key Technical Advantages:

• Ultimate Low-Noise Performance: Features specialized silencing structures and precision-ground 10/12-vane rotor systems. Even under high-pressure conditions, the operational decibel levels remain among the lowest in the industry.

• Flexible Multi-Pump Combinations: The SQP series supports up to triple-pump modularity. For instance, the SQP431 can output three different flow rates simultaneously, greatly simplifying hydraulic system plumbing.

• Superior Pulsation Resistance: Provides highly smooth flow output, significantly reducing hydraulic system vibration and extending the service life of valves and actuators.

• Modular Cartridge Kit Maintenance: Features a “drop-in” cartridge system. During maintenance, performance can be restored by simply swapping the internal kit without dismantling the pump body, drastically reducing downtime.

• Target Applications: Plastic injection molding machines, precision die-casting machines, hydraulic press brakes, automated production lines, and various heavy-duty silent power units.
