Gear oil pump QXM Series QXM42-025R-HS-FSKRG1PA

ℹ️ Product Description

Supplied by Hengmeisi, Bucher's Gear oil pump QXM Series QXM42-025R-HS-FSKRG1PA is a high-speed gear motor with "HS" design for continuous operation up to 10,500 rpm. Featuring 25cc displacement, right-hand rotation, and custom FSKRG1PA interface, it's quality-controlled for consistent performance in harsh conditions.

✨ Product Advantages

⚡ Ultra-High Speed Capability

QXM42-025R-HS-FSKRG1PA supports continuous speeds up to 10,500 rpm (max), 2–3× faster than standard gear motors. Its reinforced double-row angular ball bearing handles high external radial loads, ensuring stability at extreme speeds.

🔇 Ultra-Low Noise & High Efficiency

Optimized CAE tooth profile minimizes meshing noise (<75dB(A)) and pressure pulsations. Hydrodynamic lubrication reduces friction losses, achieving >96% volumetric efficiency and lower operating temperatures—extending fluid and component life.

📦 Compact & Lightweight Build

Integrated high-strength cast iron housing saves 30% space vs conventional motors. The FSKRG1PA custom flange and shaft design enable direct replacement in tight installations, perfect for mobile and compact systems.

🛡️ Heavy-Duty Durability

Withstands 240bar continuous / 280bar peak pressure. Wear-resistant alloy steel gears, anti-aging seals and integrated anti-cavitation valve ensure long service life in cyclic or harsh environments.
