Tokio Keiki SQP2-12-1B-18 Vane Pump
The SQP2-12-1B-18 is a fixed displacement single vane pump manufactured by Tokio Keiki, specifically engineered for industrial hydraulic systems that require a combination of moderate flow and ultra-quiet operation. As a member of the SQP series, this pump is optimized to minimize pressure ripples and acoustic vibration, making it a preferred power source for indoor machinery such as CNC lathes, small presses, and automated assembly lines. The SQP2 frame provides a robust housing that ensures long-term durability even under continuous high-pressure cycles.

Key Features for Industrial Applications
Industry-Leading Low Noise Performance
The SQP2-12-1B-18 utilizes Tokio Keiki’s advanced vane technology to deliver smooth, quiet fluid power. By reducing the pressure pulsations at the discharge port, the pump significantly lowers the overall noise level of the hydraulic power unit. This creates a safer and more comfortable work environment and can often eliminate the need for expensive secondary noise dampening.
Flexible «B» Port Orientation
The «B» designation indicates that the outlet port is positioned at a 90-degree clockwise angle relative to the inlet. This configuration allows for flexible piping and hose routing in compact machine compartments. The ability to specify port orientation ensures that the SQP2-12-1B-18 can be integrated into existing systems with minimal modification to the plumbing.
