Gear oil pump QX Series QX31-032/21-016R

📄 Product Description

From trusted China supplier Hengmeisi, the Gear oil pump QX Series QX31-032/21-016R dual internal gear pump outperforms traditional external pumps in efficiency, stability, and durability—ideal for compact hydraulic systems with dual-displacement flexibility and high-pressure capability for industrial and mobile applications.

🏆 Core Product Advantages

Internal Gear vs. External Gear Pump Designs

Unlike conventional external gear pumps, which suffer from high pulsation and meshing losses, the QX31-032/21-016R uses precision internal gear technology. This design eliminates dead zones, minimizes leakage, and delivers smoother, quieter operation at higher pressures. The result is consistent flow, reduced energy waste, and less wear on system components.

Versatile Dual-Displacement Configuration

The integrated 32cc/16cc dual pump setup offers unmatched flexibility. The two sections operate independently or in tandem, allowing the system to use only the required flow for each task. This reduces unnecessary power draw, lowers heat buildup, and improves overall system efficiency compared to single-displacement alternatives.

Premium Materials for Extended Service Life

• Gears & Housing: High-grade alloy steel, heat-treated and precision-ground for exceptional wear resistance and structural integrity.

• Sealing System: Imported high-temperature elastomers, rated for -25°C to +110°C, ensuring leak-free performance at full working pressure.

• Bearings: High-precision components engineered to handle radial and axial loads, supporting continuous operation up to 4000 r/min.

Built-In Contamination Control & Cavitation Resistance

Optimized internal flow paths reduce turbulence and cavitation, protecting the pump from damage caused by fluid starvation. Integrated filtration zones trap impurities, safeguarding critical components and ensuring long-term reliability even in less-than-ideal fluid conditions.

🔢 Model Code Breakdown

The QX31-032/21-016R features a clear, user-friendly naming convention, allowing customers to quickly identify key specifications without specialized hydraulic knowledge:

• QX31: Series identifier for high-pressure internal gear pumps.

• 032/016: Dual pump displacements (32cc/rev and 16cc/rev), highlighting its split-flow capability.

• R: Right-hand rotation, ensuring compatibility with standard system configurations.

This pump is optimized for compact, low-noise, and high-efficiency scenarios, making it a preferred choice for global buyers in material handling, machine tools, and mobile machinery.

🛠️ Product Structure

1.Core Architecture: Precision Internal Gear Set

Tight-tolerance internal/external gear pairs eliminate the high wear and pulsation common to external gear pumps, ensuring smooth, consistent flow.

2.Dual Pump Mechanism: Adaptive Split-Flow Operation

Independent pump sections allow the system to switch between low and high flow modes, adjusting effective displacement to match load demands.

3.Material Upgrades for Harsh Environments:

♢ Gears & Housing: Hardened alloy steel for superior wear and impact resistance.

◇ Seals: High-performance compounds with wide temperature and chemical compatibility.

4.Enhanced Protection & Reliability:

Optimized inlet geometry and built-in filtration prevent blockages and wear, ensuring consistent performance in dirty industrial conditions.

🚜 Application Scenarios

• Material Handling: Forklifts, scissor lifts, and pallet jacks requiring compact, reliable power units.

• Machine Tools: Hydraulic power units for presses, lathes, and injection molding machines.

• Construction & Agriculture: Small excavators, tractors, and auxiliary hydraulic systems.

• General Industrial: Hydraulic power packs, conveyor systems, and process equipment prioritizing low noise and efficiency.
