Bosch Rexroth AZPF-11-008RCB20MB Gear Pump

Bosch Rexroth AZPF-11-008RCB20MB Nam Hai Gear Pump is a product in the field of external gear pump / hydraulic gear pump / industrial hydraulic pump / open circuit hydraulic system, developed by Bosch Rexroth and supplied by Nam Hai Engineering Joint Stock Company to mechanical engineering and machinery manufacturing enterprises, lifting equipment, construction machinery, agricultural machinery, and units using hydraulic drive systems.
The product is used to generate oil flow in hydraulic systems, providing hydraulic power to cylinders, motors, valves, and actuators on machines. The AZPF-11-008RCB20MB is suitable for presses, forklifts, lifting tables, conveyors, construction equipment, lubrication systems, and applications requiring compact gear pumps with relatively high operating pressure.
Pump selection is not solely based on the model. The solution must be determined based on flow rate, pressure, rotational speed, direction of rotation, shaft type, flange, port connection, oil type, operating temperature, and the hydraulic circuit configuration of each machine.

1. Key Features of the Product

According to information published by Nam Hai, the Bosch Rexroth AZPF-11-008RCB20MB has a displacement of 8 cm³/rev.
The nominal flow rate is approximately 12 L/min at 1,500 rpm, and the maximum flow rate is approximately 28 L/min.
The nominal operating pressure is 250 bar, while the maximum intermittent pressure can reach 280 bar.
The pump uses an external gear pump design with an aluminum alloy body, which helps create a relatively compact structure and reduces equipment weight.
The stated operating speed range is 500–3,000 rpm, with a maximum speed of approximately 3,500 rpm.
The model uses right-hand rotation, and the correct shaft type, flange, and port connection must be checked before replacement or integration into a system.

3.3. Information Customers Need to Provide

Customers should provide:
- Current pump model.
- Nameplate image.
- Machine model or hydraulic power unit.
- Required flow rate.
- Operating pressure.
- Motor speed.
- Direction of rotation.
- Shaft type.
- Flange type.
- Size and type of port connection.
- Type of oil currently in use.
- Operating temperature.
- Hydraulic schematic, if available.
- Failure symptoms if replacing an old pump.
The more complete the information, the more accurately compatibility can be checked and the pump selected to suit actual operating conditions.

3.4. System Inspection and Evaluation

Before installation, it is necessary to check the model, displacement, direction of rotation, shaft type, flange, and port connection to avoid using a pump incompatible with the existing machine.
At the same time, it is necessary to evaluate the oil condition, cleanliness of the hydraulic system, filter, suction and return lines to minimize the risk of damage to the new pump due to contamination, cavitation, or unsuitable operating conditions.
After installation, the system should be checked for pressure, flow rate, temperature, noise, and the operation of the actuators to confirm stable pump operation.

4. Benefits for Customers and Businesses

The Bosch Rexroth AZPF-11-008RCB20MB helps businesses build or maintain oil supply for hydraulic systems with 8 cm³/rev displacement and a nominal pressure of 250 bar.
The relatively simple external gear pump design, compact size, and the ability to achieve a maximum flow rate of approximately 28 L/min make the product suitable for various industrial machinery and power units.
Thus, businesses can establish a process from identifying hydraulic requirements → pump selection → connection check → installation → commissioning → pressure and flow evaluation → operation optimization.
