TOKIMEC SQP321-21-17 Triple Fixed Displacement Vane Pump, 21+17 cm³/rev, Low Noise, Standard CW Rotation, 90° CW Middle & Cover Delivery, Design 18

TOKYO KEIKI SQP321-21-17 Triple Fixed Displacement Vane Pump, 21-17 cm³/rev, Low Noise, Parallel Square Key, 90° CW Middle & Cover Delivery, Clockwise Rotation, Design 18

The TOKYO KEIKI SQP321-21-17 is a high-performance, low-noise triple fixed displacement vane pump, meticulously engineered for demanding industrial hydraulic applications. As a distinguished model within the renowned SQP series, it is acclaimed for its robust construction, exceptional efficiency, and significantly reduced operating noise levels, ensuring a more comfortable and productive working environment.

This specific configuration, SQP321-21-17, designates a triple pump design. It features a shaft-end pump (SQP3 series) with a displacement of 21 cm³/rev and a middle pump (SQP2 series) providing 17 cm³/rev. While the model number suggests a third, cover-end pump, its specific displacement code '1' is not explicitly detailed in the general displacement tables of the manufacturer's provided documentation, indicating it is likely a very small or specialized displacement. This multi-stage design enables versatile hydraulic circuits, providing various flow rates crucial for complex machinery operations. The shaft end is configured with a parallel square key (code '86' would typically be present in a full model code for this, though not explicitly in your 'SQP32-21-17-1DD-18', it's a standard feature for SQP series pumps), ensuring a secure and reliable mechanical connection to the drive system.

Regarding the delivery port positions, the "DD" code specifies that both the middle pump (SQP2 series) and the cover-end pump (SQP1 series) have their delivery ports oriented 90° clockwise (CW) from their respective suction ports. The rotational direction, inferred from the absence of a 'LH' (Left-Hand) code, is standard clockwise (CW) when viewed from the shaft end, which is vital for correct system integration. This pump is manufactured under Design Number 18, representing its specific revision and configuration.

Designed primarily for mineral oil-based hydraulic fluids, the SQP321-21-17 model ensures reliable operation across a broad spectrum of pressures and speeds. Its advanced vane pump technology guarantees stable flow and pressure, contributing to precise control and extended service life for your hydraulic systems. The incorporation of cutting-edge low-noise technology makes this pump particularly well-suited for applications where acoustic emissions are a critical concern, helping meet both environmental and workplace safety standards.
