Product Description


SQP Series-double Pumps  Overview


The SQP Series Double Vane Pumps are low-noise, high-efficiency hydraulic pumps designed for industrial machinery and machine tool applications. Featuring a modular double-pump structure, they provide two independent flow outputs within one compact unit, offering stable performance, high reliability, and long service life. With precision-engineered vanes and low-vibration operation, the SQP Series is ideal for systems requiring smooth, energy-efficient hydraulic power under continuous operation.

SQP Series Vane Pumps


Key Features & Advantages:



1. Dual Pump Design


  • Integrates two fixed-displacement vane pump sections on the same drive shaft, allowing independent dual-circuit outputs.

  • Compact construction saves installation space and simplifies hydraulic circuit design, providing greater system flexibility.


2. Low Noise and Vibration


  • Specially engineered for quiet operation with optimized flow passages and pulsation-reduction design.

  • A reinforced housing and high-precision manufacturing minimize vibration and noise, ideal for noise-sensitive equipment such as machine tools and injection molding machines.

3. High Pressure and Superior Performance


  • Uses high-performance intra-vane technology with a maximum working pressure of up to 17.5 MPa (175 bar).

  • Delivers stable flow, high volumetric efficiency, and reliable operation under heavy-duty conditions.

4. Modular and Interchangeable Construction


  • Features a standardized cartridge kit design for quick maintenance and easy replacement.

  • Pump cores are interchangeable with the V-Series, ensuring part compatibility, reducing spare-part inventory, and lowering maintenance costs.

5. Flexible Configuration and Wide Application Range


  • Available in multiple frame sizes (SQP21, SQP31, SQP32, SQP41, SQP42, SQP43, etc.) and displacement combinations.

  • Compatible with various hydraulic fluids, including mineral oils and fire-resistant fluids (water-glycol, phosphate ester).

  • Widely used in machine tools, die-casting machines, injection molding machinery, forging equipment, and other industrial hydraulic systems.

6. High Reliability and Easy Maintenance


  • Robust housing and precision components ensure durability and resistance to pressure and vibration.

  • Cartridge-type design allows fast disassembly and maintenance without removing the entire pump, minimizing downtime.

7. Energy Efficiency and Cost Effectiveness


  • Dual-displacement output enables efficient flow distribution according to load demand, improving energy utilization.

  • Simplifies hydraulic system design, reduces operational and maintenance costs, and enhances overall system efficiency.

Packaging & Delivery


Vane pumps are typically packaged securely to prevent damage during transit. The packaging includes:

Protective Wrapping: To safeguard the pump from environmental damage.

Custom Crates: For larger, heavier pumps, ensuring safe handling.

Documentation: Includes installation, maintenance instructions, and warranty details.

Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.
