Gear oil pump QX Series QX23-006R117-1

ℹ️ Product Description

Looking for a factory-direct price manufacturer? Hengmeisi Gear oil pump QX Series QX23-006R117-1: robust 6.3cc internal gear pump from China factory direct. Replaces external gear pumps – offers pressure stability, low noise, long life for critical hydraulic circuits.

✨ Product Advantages

⚙️ Internal Gear vs. External Gear Pump Design

Unlike traditional external gear pumps prone to high pulsation and wear, the QX23-006R117-1 uses an internal gear pair with hydrodynamic lubrication. This eliminates metal-to-metal contact, reduces noise, and enables higher pressure capacity (up to 400bar peak) while maintaining smooth, consistent flow.

📉 Ultra-Low Pulsation & Quiet Operation

Featuring precision-machined gear profiles, the QX23-006R117-1 operates with minimal pressure ripple (<2% flow variation) and noise levels below 75dB(A). This ensures stable system performance and reduces stress on downstream components in sensitive hydraulic circuits.

🔩 Heavy-Duty Materials for Long Life

Gear Set: High-strength alloy steel, heat-treated and precision-ground for wear resistance.

Housing: Cast iron body with optimized flow paths to reduce turbulence.

Seals: High-temperature-resistant FPM seals, rated for -20°C to +80°C.

Bearings: Heavy-duty roller bearings supporting continuous speeds up to 3600 rpm.

🛡️ Built-In Contamination Resistance

An integrated anti-pollution filter protects the gear set from hydraulic fluid impurities, preventing premature wear. The robust design ensures reliable operation even in environments with marginal fluid quality, critical for long-term performance in industrial settings.

🔤 Model Code Explanation

The QX23-006R117-1 naming convention is intuitive for quick identification:

• QX23: Series identifier for high-pressure compact internal gear pumps

• 006: Displacement of 6.3 cm³/rev, ideal for low-flow, high-pressure applications

• R: Right-hand (clockwise) rotation

• 117-1: Custom seal and port configuration for specialized system requirements

This model is optimized for precision hydraulics, making it widely trusted by global buyers in machine tools, construction machinery, and material handling equipment.

🧩 Product Structure

🏗️ Core Architecture: Internal Gear Mechanism

The QX23-006R117-1 features a compact internal gear design with a crescent-shaped separator. This structure enables higher pressure capacity and efficiency compared to external gear pumps, all within a smaller footprint.

💧 Optimized Flow Path Design

Precision-cast flow paths minimize turbulence and pressure drop, maximizing volumetric efficiency at high pressures. The inlet and outlet are strategically positioned to ensure consistent fluid distribution across the gear set.

🛠️ Material Upgrades for Durability

The pump body is made of high-grade cast iron for structural rigidity and vibration damping.

Gear teeth are case-hardened to resist wear under continuous high-pressure cycles.

Shaft seals are designed for long life and reliable leak prevention.

🧷 Standard Mounting Interface

The QX23-006R117-1 features an ISO 3019-2 standard flange, ensuring easy installation and interchangeability with existing systems. The compact dimensions make it ideal for space-constrained applications.
