This unit is engineered to provide three independent hydraulic flows from a single shaft input, maximizing efficiency and saving valuable installation space. It is famous in the industry for its «Low Noise» operation, making it the preferred choice for indoor hydraulic power units in plastic injection molding machines and die-casting equipment.
Technical Specifications and SQP Series Reliability
The SQP432 configuration combines three pump cartridges in frame sizes 4, 3, and 2. The **»60″** indicates the shaft-end pump displacement (approx. 193 L/min at 1200 rpm), **»35″** for the middle pump (approx. 111 L/min), and **»17″** for the cover-end pump (approx. 55 L/min). The **»86″** designates a robust parallel square key shaft. The suffix **»DDC»** refers to the specific orientation of the discharge ports relative to the suction port, ensuring seamless plumbing integration.

Expert Maintenance Tips: Cartridge Replacement
The beauty of the SQP series is its serviceability. Expert Tip: If flow drops, you don’t need to replace the whole housing. You can replace just the internal cartridge kits. When changing a cartridge, verify the **O-ring condition** on the intra-vane ports. Also, ensure the rotation direction of the new cartridge matches the shaft rotation (Right-Hand is standard). Incorrect installation will cause immediate cavitation and noise.
Frequently Asked Questions (FAQs)
Q: Is this interchangeable with Vickers VQ series?
A: Functionally yes, they are both vane pumps, but the SQP is specifically optimized for lower noise levels («Quiet Pump»). Mounting dimensions (SAE) are often compatible, but always check the bolt pattern and shaft length.
Q: What viscosity oil should I use?
A: Tokyo Keiki recommends ISO VG32, VG46, or VG68 anti-wear hydraulic oil for optimal life and noise performance.
