The AZPG-22-045RQC40MB pump is part of the High Performance AZPG Gear Pumps series from Bosch Rexroth and is applied in hydraulic automation to deliver fixed-volume flow. Its geometric displacement of 45 cm³ per revolution establishes the volume moved each cycle, while clockwise rotation matches right-hand drive arrangements already common on mobile machinery. Twelve gear teeth share loading evenly to reduce pressure ripple and gear wear. A maximum rotational speed of 2600 rpm supports high throughput operations, and the minimum speed of 500 rpm below 100 bar prevents starvation at light loads. NBR sealing material confines the working fluid and withstands standard hydraulic oils. For maintenance planning, the unit is identified by order reference 9510490087.
The front cover flange follows the SAE J744 101-2 two-hole 101.6 mm pattern so it mounts directly to standardized pump pads. Fluid is routed through an SAE rectangular flange with UNC threads, simplifying pipework in modular power units. Continuous system duty is supported up to 250 bar, and intermittent peaks up to 225 bar can be tolerated for short loading events. A maximum shaft torque of 180 Nm defines the drive strength required from the prime mover. When pressure reaches 180 bar, the pump must turn at least 1000 rpm to sustain lubrication and flow stability. These limits outline a safe operating window for automated hydraulic circuits that rely on consistent gear pump performance.
