AZPF-11-004RAB1MB

The AZPF-11-004RAB1MB pump belongs to the AZPF External High Performance Gear Pumps series and is manufactured by Bosch Rexroth for hydraulic automation where a constant oil supply is needed. Its displacement is 4 cm³ per revolution, determining the fixed volume delivered with each shaft turn. Clockwise rotation is required so the inlet and outlet are oriented correctly within the circuit. A maximum speed of 4000 rpm supports fast cycling while keeping internal wear under control. The pump endures intermittent pressures up to 280 bar, allowing short peaks during load changes. A shaft torque limit of 75 Nm defines the highest twisting force that can be applied without damaging the drive train. It operates in ambient temperatures from –30 °C to +80 °C, making it suitable for both cold storage facilities and warm production areas. There are no restrictions on installation position, so the housing can be mounted in any attitude to suit compact layouts.

The gear set uses 12 teeth; this count affects flow ripple and assists in steady pressure delivery. Mounting is secured with M6 bolts, giving compatibility with standard metric hardware. A flange spigot diameter of 80 mm centers the body against mating surfaces to keep shaft alignment accurate. Each mounting hole is 13 mm deep, guiding bolt length choices to achieve full thread engagement. Hydraulic connections employ a G 1/2 ISO 228 port thread so common tube fittings can be fitted without adapters, and a 16 mm thread depth provides enough engagement for reliable sealing. The pump weighs 3.3 kg, allowing one technician to handle installation while indicating a solid cast construction that resists vibration.
