Product Overview
The SQP321 Series is a sophisticated triple fixed displacement vane pump engineered specifically for low-noise industrial environments. By integrating three independent pumping sections (Sizes 3, 2, and 1) into a single housing driven by one shaft, the SQP321 offers unparalleled versatility for complex hydraulic circuits while significantly reducing the installation footprint.
With over 9 years of specialized manufacturing experience, YHDE produces the SQP321 series to be 100% interchangeable with Tokimec (Tokyo Keiki) and Vickers specifications. It is the ideal "drop-in" solution for high-end plastic machinery and industrial power units where quiet operation is mandatory.
Core Features & Benefits
Ultra-Low Noise Technology: The SQP series is world-renowned for its quiet performance, making it the preferred choice for indoor factory environments and precision machinery.
Triple Circuit Flexibility: Provides three independent oil flows, allowing for simultaneous control of multiple hydraulic functions such as high-speed approach, pressing, and auxiliary cooling.
Pulse-Free Performance: The multi-vane design ensures smooth, steady flow with negligible pressure pulsation, protecting sensitive downstream components.
Modular Maintenance: Built with independent cartridge kits for each section (SQP3, SQP2, and SQP1), allowing for quick on-site repairs and easy displacement changes without removing the entire pump.
High Efficiency: Precision-ground internal components ensure high volumetric efficiency and reduced heat generation, contributing to overall energy savings.
