Tokimec Type SQP Series Vane Pump | SQP1, SQP21, SQP43, SQP3 | Low Noise

Tokimec Type SQP Series Ultra-Low Noise Industrial Vane Pumps

Product Overview: The SQP Series is widely recognized as the “Quiet King” of the hydraulic industry. Engineered as a fixed displacement vane pump for indoor factory environments and precision machinery, the SQP series utilizes multi-stage pulsation suppression technology to achieve exceptionally low operational decibels. This selection features core single and double models: SQP3-32-1D-18, SQP21-21-14, SQP43-60-38-86CC-18, and SQP41-75-8-86CC-18. Featuring precision-ground port plates, this series maintains superior volumetric efficiency even at pressures up to 21.0 MPa (210 Bar), making it the definitive power source for injection molding machines, CNC tools, and press systems.

Key Technical Advantages:

• Ultimate Low-Noise Performance: Optimized internal flow channels and a 12-vane rotor structure keep decibel levels significantly lower than gear or piston pumps—perfect for enhancing workshop environments.

• Flexible Double & Multi-Pump Configurations: Architectures like SQP21 and SQP43 allow two different displacement cartridges (e.g., 60 and 38 GPM) on a single shaft, ideal for independent dual-circuit control or combined high-flow output.

• Rapid “Drop-in” Cartridge Maintenance: The internal pump core is a modular unit. Maintenance is streamlined—swap the internal cartridge on-site to restore performance without disconnecting heavy plumbing, drastically cutting downtime.

• High-Pressure Durability: High-strength ductile iron housings paired with a balanced core minimize bearing loads, ensuring extended service life under continuous heavy-duty cycles.

• Target Applications: Plastic injection machines, rubber machinery, die-casting equipment, hydraulic cutting tools, shoemaking machines, and industrial Hydraulic Power Units (HPU).
