Product Description
SQP & SQPS Series High-Performance Low Noise Vane Pumps
Product Overview: The SQP Series is widely recognized as the “Silent Expert” in the hydraulic power industry, specifically engineered for industrial applications with stringent noise requirements. Featuring an advanced cartridge-based design, the SQP series delivers stable high-pressure output with exceptional operational smoothness. This featured range includes the single pump SQPS3-38-1C-18, the compact SQP S21-21-4-11DC-18, and high-capacity double pumps like SQP21-12-3-1BB-18 and SQP43-60-38-86CC-18. Utilizing a pressure-balanced construction, the SQP series minimizes radial loads to extend bearing life and reduce pulsation—making it the premier choice for injection molding machines and automated production lines.
Key Technical Advantages:
Ultra-Quiet Operation: Especially in the SQPS (Silent) series, optimized vane geometry and silencing grooves keep decibel levels significantly lower than conventional pumps, enhancing the workplace environment.
Rapid Maintenance with Cartridge Kits: The internal components feature a “drop-in” modular design. Maintenance is streamlined—swap the cartridge kit without disconnecting main plumbing to restore 100% factory performance and minimize downtime.
Flexible Double Pump Integration: Models like SQP21 and SQP43 integrate two independent displacement cartridges within a single housing, allowing one drive shaft to power separate high-pressure and auxiliary circuits while saving space.
High Responsiveness & Durability: Built-in automatic clearance compensation ensures the pump maintains superior volumetric efficiency even after prolonged use, reducing internal leakage and system heat.
Target Applications: CNC machine tools, plastic processing machinery (injection molding), aluminum die-casting machines, bending machines, and various industrial Hydraulic Power Units (HPU).
