AZPF-10-019RQRXXMB-S0140 Rexroth Gear Pump 210Bar

Product Overview

The AZPF-10-019RQRXXMB-S0140 is a high-performance, high-pressure external gear pump engineered specifically for mobile machinery and stationary industrial hydraulic systems. Belonging to the proven Bosch Rexroth AZPF Group 1/2 platform and featuring a specialized configuration suffix (S0140), this model plays a pivotal role in auxiliary and main power distribution. Positioned as a premium B2B industrial replacement solution, its definitive competitive advantage is Absolute Interchangeability. Customers can seamlessly drop this unit in to replace original Rexroth pumps without altering existing mounting flanges, shaft extensions, or piping lines. To back our commitment to uncompromising reliability, every single AZPF gear pump undergoes 100% simulated load testing on automated test rigs prior to dispatch, ensuring leak-free, high-efficiency operation right out of the box.

Key Technical Advantages

• Dynamic Axial Clearance Compensation: Featuring advanced floating side plates that utilize system discharge pressure to dynamically seal against the gear faces. Even under continuous 210 bar operations, this minimizes internal leakage and maintains a volumetric efficiency above 95%.

• Seamless Drop-in Replacement: Manufactured to strict Bosch Rexroth official tolerances, down to the micron. Both mounting dimensions and port orientations ensure a flawless, direct fit during machine overhauls, drastically cutting down adaptation time and procurement expenses.

• Rigorous 100% Simulated Load Testing: We reject random batch sampling. Every manufactured AZPF-10-019RQRXXMB-S0140 pump is subjected to automated tests simulating full pressure loads, pressure spikes, and thermal cycles, completely eliminating out-of-box failure risks.

• High Fatigue Strength & Low-Noise Gear Geometry: The core gear clusters are crafted from premium high-strength alloy steel with precision tooth profile modifications. This enhances bending and torsional fatigue resistance while reducing fluid-borne pulsation and mechanical noise.

Application Area

Thanks to its compact footprint and robust high-pressure capability, the AZPF-10-019RQRXXMB-S0140 is widely deployed across various mobile and industrial machinery:

• Mobile Machinery: Mini excavators, skid steer loaders, agricultural tractors, and combine harvester working hydraulic circuits.

• Material Handling: Industrial forklifts, aerial work platforms (AWPs), and hydraulic tailgate lift systems.

• Industrial Automation: Compact Hydraulic Power Units (HPUs), CNC machine tool auxiliary lubrication, and clamping stations.

Expert Maintenance Tips

• Strict Fluid Cleanliness Control: Gear pumps are sensitive to particulate contamination. We strongly recommend maintaining a return filtration level of ISO 4406 18/16/13 or better, and replacing filter elements regularly to prevent particle trapping between gear teeth.

• Mandatory Pre-filling to Prevent Cavitation: Upon initial installation of the AZPF-10-019RQRXXMB-S0140 or after a fluid change, never run the pump dry. Manually prime the pump casing with clean hydraulic fluid through the inlet port and jog the motor to bleed out trapped air lines, avoiding catastrophic cavitation wear on journal bearings.

• Precise Shaft Alignment: When coupling to the drive motor, always use a high-quality flexible coupling and ensure the concentricity tolerance between the pump shaft and drive shaft is kept within 0.1mm. Excessive radial loads will lead to premature shaft seal wear or oil leakage.
