Gear oil pump QX Series QX63-100L

ℹ️ Product Description

For large-flow, high-pressure single-circuit systems, Hengmeisi's Gear oil pump QX Series QX63-100L internal gear pump features a robust 100cc single-stage design, outperforming standard pumps in pressure stability, wear resistance, and temperature adaptability—ideal for heavy-duty machinery and demanding industrial applications.

✨ Product Advantages

⚙️ Robust Single-Stage Gear Design vs. Multi-Stage Pumps

Unlike multi-stage pumps that require complex assembly, the QX63-100L features a simplified, heavy-duty single-stage internal gear design. This reduces the risk of failure points, lowers maintenance complexity and ensures consistent, high-volume flow output under constant heavy loads. The direct-drive layout improves power transmission efficiency, minimizing energy loss compared to split-flow pump configurations.

📉 Ultra-Low Pulsation & Vibration-Free Operation

Built with precision internal gear pairs and optimized flow paths, the QX63-100L operates with extremely low flow pulsation and mechanical vibration. The smooth internal meshing eliminates the pressure spikes common to external gear pumps, protecting downstream components and extending the service life of the entire hydraulic system.

🔩 Industrial-Grade Construction for Maximum Durability

• Gear & Housing: High-strength alloy steel and ductile iron construction, heat-treated for superior wear and impact resistance.

• Sealing System: High-temperature and chemical-resistant seals, rated for -35℃ to +125℃, ensuring leak-free performance in extreme conditions.

• Bearings: Heavy-duty tapered roller bearings, designed for continuous operation up to 3200 r/min and high radial loads.

🛡️ Built-In Anti-Corrosion & Filtration Features

The pump’s internal flow passages are coated with anti-corrosion materials, protecting against fluid degradation. A built-in inlet strainer prevents large particles from entering the gear chamber, reducing wear and extending service life in environments with contaminated hydraulic fluid.

🔤 Model Code Explanation

The QX63-100L naming convention clearly identifies key specifications:

• QX63: Series identifier for heavy-duty high-pressure internal gear pumps.

• 100: Displacement of 100cc/rev, designed for high-volume applications.

• L: Left-hand rotation, matching the requirements of specific system configurations.

This model is the flagship of the QX63 series, optimized for continuous high-pressure operation. It is widely trusted by global buyers in heavy construction, mining equipment and industrial presses.
