AZPG-22-036RQC40MB

The AZPG-22-036RQC40MB pump is manufactured by Bosch Rexroth for the High Performance AZPG Gear Pumps series. It supplies hydraulic flow for automation circuits where fixed displacement operation is required. A geometric displacement of 36 cm³ per revolution determines the volume moved each shaft turn, so system flow rises proportionally with speed. The permitted rotational speed reaches 2800 rpm, enabling high delivery rates in compact packages. A continuous pressure limit of 250 bar defines the maximum steady load the housing and gears can withstand. The pump also carries an intermittent rating of 250 bar, giving it the same margin for short duration overloads. Brief pressure peaks may rise to 300 bar, covering transient events during directional changes. Input torque may reach 180 Nm, guiding motor sizing and coupling selection. Clockwise rotation, viewed on the shaft, fixes the direction of inlet and outlet flow paths. The drive shaft follows the SAE J744 22-1 parallel key format, simplifying integration with standard industrial couplings.

The keyed interface uses dimensions of 6.35 × 25.4 mm, and conformance with ANSI B17.2 ensures accurate fit with mating hubs. A two-hole mounting flange to SAE J744 101-2 (B) secures the pump to power take-off pads or brackets without additional adapters. The pilot diameter of 101.6 mm centers the housing during installation and maintains shaft alignment under load. Hydraulic lines attach through an SAE rectangular flange with UNC hardware, providing a leak-tight connection at the rated pressures. Port bolts engage 3/8-16 UN-2B threads so users can apply common fasteners when assembling the flange. An NBR shaft seal prevents oil escape and blocks contaminants from entering along the shaft. The seal size of 42 × 26 × 7 mm matches replacement inventory in standard maintenance kits. These dimensional and connection features help installers mount the pump quickly and maintain reliability in continuous industrial service.
