The core gear pair of Hengmeisi QX51-080R12 gear oil pump is made of high-quality alloy steel with professional surface quenching hardening treatment up to HRC60 hardness. This process enables Hengmeisi gear oil pump to resist wear and impact under long-term continuous operation.

Hengmeisi QX51-080R12 gear oil pump is equipped with imported high-pressure composite sealing components. The upgraded sealing system of Hengmeisi gear oil pump adapts to -30℃ to +120℃ wide temperature environment. This Hengmeisi gear oil pump achieves zero leakage under maximum peak pressure, effectively solving the oil leakage failure of ordinary gear pumps. All supporting bearings and drive shafts of Hengmeisi QX51-080R12 gear oil pump adopt high-hardness anti-corrosion materials to ensure stable operation for a long time.

3.3 Low Noise & Low Pulsation, Stable Operation

Hengmeisi QX51-080R12 gear oil pump adopts large overlap angle internal gear layout. This structural feature greatly reduces oil supply pulsation and mechanical vibration of the gear oil pump. The full-load running noise of Hengmeisi QX51-080R12 gear oil pump is controlled below 65dB. The low-vibration and stable oil supply performance of Hengmeisi gear oil pump avoids pipeline vibration and accessory wear caused by unstable hydraulic output. This Hengmeisi gear oil pump can adapt to precision production workshops and low-noise industrial working environments.

3.4 Strong Medium Compatibility & Anti-Pollution Ability

Hengmeisi QX51-080R12 gear oil pump supports a variety of hydraulic medium applications. This Hengmeisi gear oil pump is compatible with mineral hydraulic oil, biodegradable hydraulic fluid, fire-resistant hydraulic oil and other special media. Hengmeisi optimizes the internal flow channel structure of this gear oil pump to reduce fluid turbulence and impurity deposition. The self-protection flow channel design effectively filters tiny impurities in hydraulic oil and protects the core gear pair of Hengmeisi QX51-080R12 gear oil pump.
