⚙️ Product Description

Hengmeisi offers reliable products that meet Rexroth standards.

Gear oil pump GXPO Series GXPO-AOA15ABL-21, built under strict quality control. Featuring integrated forming and high‑hardness alloy, it resists oil contamination and hydraulic shock, runs with low heat, and has durable seals. It supports long‑term continuous operation and delivers stable output for complex hydraulic systems.

🌟 Core Product Strengths

🛡️ Upgraded Cycloid Gear Technology

Different from conventional straight-tooth pumps, this GXPO model adopts optimized cycloid tooth profile design. It minimizes flow fluctuation and pressure ripple, achieving smoother fluid transmission, lower operating noise and higher volumetric efficiency under variable load conditions.

💪 Enhanced Anti-Impact & Anti-Pollution Capacity

Featured with upgraded internal oil circuit and filter protection structure, the pump is highly tolerant of contaminated hydraulic oil and sudden load changes. It effectively avoids stuck gears and abnormal wear, maintaining consistent performance in harsh construction and industrial working scenarios.

🔥 Low Heat Generation & Durable Operation

Matched with high-precision wear-resistant bearings and heat-conductive aluminum alloy housing, the pump reduces friction loss and heat accumulation during high-speed operation. It effectively prevents thermal attenuation and ensures long continuous service life under high-load working cycles.

🔒 Premium Integrated Sealing System

Equipped with multi-layer composite high-temperature resistant seals, it adapts to wide temperature and variable working pressure environments. The integrated anti-leakage design eliminates oil seepage issues, keeping the entire hydraulic system clean, energy-saving and stable.
