SQP Series Vane Pump
Product Overview
SQP Series Vane Pump is a high‑performance fixed‑displacement Hydraulic Vane pump. As an important hydraulic pump, it supplies stable high‑pressure oil flow for the hydraulic system of various industrial Machine. This hydraulic pump adopts balanced vane structure design, featuring low noise, high volumetric efficiency and outstanding pressure resistance. Single, double, triple and quadruple pump combinations are optional to satisfy multi‑circuit power demands. It guarantees smooth and reliable operation of the whole hydraulic system, and is widely used for OEM assembly and spare‑part replacement of different Machine.

Working Principle
The Hydraulic Vane pump SQP converts rotational mechanical energy into hydraulic energy. The rotor drives vanes sliding closely along the cam ring to form sealed oil chambers. Oil is sucked into the pump cavity, pressurized and delivered steadily to the hydraulic system. Multi‑unit tandem hydraulic pump can output independent flow for several hydraulic loops on one Machine. The balanced pressure‑offset structure reduces side‑force on rotating parts, lowering wear and prolonging service life inside the hydraulic system. When performance drops, the whole cartridge kit can be replaced directly without disassembling the entire pump body.
Core Advantages
1. Balanced pressure‑offset structural design, small shaft load, low wear, long service life for heavy‑duty Machine.
2. Excellent volumetric efficiency, stable flow output, maintaining consistent working performance of the hydraulic system.
3. Optimized internal profile, ultra‑low noise operation, suitable for indoor workshop‑running Machine.
4. Modular cartridge insert, quick maintenance and component swap, shortening downtime of the hydraulic pump.
5. Abundant combined pump selections, flexible flow matching for complex multi‑loop hydraulic system.
6. Standard installation and port dimensions, great interchangeability, convenient for retrofitting existing Machine.
Application Scope
SQP series Hydraulic Vane pump is adopted as the main hydraulic pump for injection molding machines, punching presses, metallurgical machinery, die‑casting equipment, machine tools and other heavy‑duty industrial Machine. It provides high‑pressure power source for the hydraulic system. Widely applied in plastic factories, metal‑forming workshops, hydraulic power stations and general heavy‑industry production sites.
