Gear oil pump QXV Series QXV54-050R

ℹ️ Product Description

Leading China manufacturer and supplier Hengmeisi presents the Gear oil pump QXV Series QXV54-050R – perfect replacement for Bucher's original QXV series. Heavy-duty internal gear pump for low-viscosity fluids: 50.3 cc/rev, 150 bar, right-hand rotation. Reliable for fuels, brake fluids, ATEX – premium hydraulic solution for high-flow industrial/mobile use.

✨ Core Advantages

⚙️ High Efficiency for Thin Fluids

The QXV54-050R excels with low-viscosity fluids, achieving up to 98% volumetric efficiency even at 0.8 mm²/s. Precision-machined gears minimize leakage, while optimized flow paths reduce turbulence—ideal for fuel and brake fluid systems.

🛡️ Heavy-Duty & Durable Build

Constructed with a reinforced cast iron housing and heat-treated alloy steel gears, the QXV54-050R withstands extreme vibration and heavy loads. Its robust frame size 4 design ensures long-term reliability in harsh industrial environments.

🔇 Low Noise & Pulsation

Featuring a CAE-optimized tooth profile, the QXV54-050R operates at ~75 dB (1500 rpm) with minimal pressure pulsation. This smooth output protects sensitive components and extends system life.

🌡️ Wide Compatibility & Safety

Handles temperatures from -20°C to +160°C and works with diesel, kerosene, aviation fuels, and biodegradable oils. ATEX-certified (Ex II 3G T3/T4) for hazardous areas, ensuring operational safety.

🧩 Product Structure

🚰 Precision Gear Assembly

At the heart of the QXV54-050R are high-precision internal gears with optimized tooth profiles. The ring gear rides on a hydrodynamic lubrication film, enabling reliable low-viscosity operation.

🛠️ Reinforced Housing & Mounting

The robust cast iron body integrates reinforced mounting lugs and a standard flange, ensuring secure installation under vibration. Its compact design allows flexible orientation.

🧴 Advanced Sealing System

Multi-component FKM/NBR seals prevent leakage at the shaft and housing joints. Rated for -20°C to +160°C, they maintain integrity with low-viscosity and aggressive fluids.

⚙️ Heavy-Duty Bearing Unit

High-performance roller bearings support the gear shaft, enabling continuous speeds up to 3000 rpm. They reduce friction and extend service life under high-pressure loads.
