Gear oil pump QX Series QX33-012R12

ℹ️ Product Description

Hengmeisi's QX33-012R12 is a newly developed miniature internal gear pump (12cc) with a highly integrated structure for narrow installation spaces and stable oil supply. Precision processing and smart layout ensure long-term reliable operation—perfect for small automated devices and portable hydraulic tools.

✨ Product Advantages

📦 Ultra-Compact Integrated Structure

The Gear oil pump QX Series QX33-012R12 adopts a highly condensed overall structure with streamlined exterior design. It occupies far less installation space than conventional gear pumps and can be perfectly embedded into various mini mechanical equipment. The integrated assembly design reduces connecting parts, lowers the risk of loose connection and oil leakage, and greatly improves the overall compactness and neatness of the hydraulic system.

🤫 Stable Operation & Low Running Noise

Adopting finely polished internal gear pairs, QX33-012R12 realizes gentle meshing during operation. The gear clearance is precisely controlled, which effectively weakens mechanical friction and running vibration. Its operating noise is kept at a low level, creating a quiet working environment for indoor automated production equipment and precision instruments. The flow output stays uniform without obvious fluctuation.

🧪 Fine Selected Materials & Long Service Span

The core gears and pump body are made of wear-resistant alloy materials after multiple precision treatments, featuring high surface hardness and strong anti-fatigue ability. The matched sealing parts have outstanding aging resistance and oil resistance, which can prevent medium leakage under long-term continuous operation. Even under frequent start-stop working conditions, QX33-012R12 can maintain stable working performance.

🌤️ Strong Environmental Adaptability

This pump is optimized for diverse working environments. It can operate normally in both indoor constant-temperature workshops and outdoor simple working sites. The internal anti-dust structure can block fine dust and tiny impurities, avoiding component jamming. It is not sensitive to slight changes of oil quality, showing excellent compatibility for general hydraulic oil.

🔤 Model Code Explanation

The coding rule of QX33-012R12 is clear and easy to recognize:

• QX33: Special series for miniature compact internal gear pumps

• 012: Nominal displacement of 12cc per revolution

• R12: Specified right rotation direction and standard installation interface

This model is a classic product of QX33 series, favored by buyers for its small size, stable performance and competitive price, and widely circulated in the field of miniature hydraulics.
