Advantages and characteristics of Rexroth gear pumps

I. Core performance advantages

‌High efficiency and energy saving‌

Using precision gear design and optimized bearing structure, low friction, low leakage, high energy transfer efficiency, nominal pressure up to 280 bar, flow rate covers 5 cm³/rev to large displacement requirements.

The inclined plate axial piston pump supports stepless flow regulation, adapts to servo motor drive, and significantly improves energy utilization.

‌Low noise and stability‌

The optimized fluid power system combined with precision machining technology has significantly lower operating noise than similar products, and pressure fluctuations can be controlled within 1%.

The sliding bearing design (such as the AZPF series) is suitable for heavy-duty conditions and has a longer service life.

‌Wide applicability‌

Supports the transportation of various liquids such as lubricating oil, hydraulic oil, and water-based media, suitable for metallurgy, shipbuilding, engineering machinery and other fields.

The modular combination design (such as the SILENCE series) supports multi-pump parallel connection to meet the needs of complex hydraulic systems.

II. Design and adaptation capabilities

‌Standardization and flexibility‌

The drive shaft is compatible with ISO/SAE standards, which is easy to integrate into different equipment.

Provide a variety of models (such as AZPF-1X series, AZPB-32 series), suitable for high pressure, precision, corrosive and other special environments.

‌Durability and maintenance convenience‌

The gray cast iron pump cover and reinforced sealing design are used, with excellent corrosion resistance, suitable for polluted environments or water-based media.

The structure is compact, key components (such as floating sleeves) are easy to disassemble and replace, and the maintenance cost is low.

Precautions for use

I. Operation specifications

‌Check before starting ‌

Confirm that the motor direction is correct (forward rotation is clockwise, reverse pump needs to be counterclockwise), and check whether the transmission key is installed in place.

Before filling water or oil, ensure that the pipeline is not loose and the oil inlet filter is completely immersed below the oil surface.

‌Operation monitoring ‌

The bearing temperature must be controlled within the ambient temperature + 35℃, and the maximum shall not exceed 80℃; if abnormal noise is found, the machine must be stopped immediately for investigation.

Regularly check the dripping of the packing gland, and keep 1~2 drops per minute.

2. Maintenance and management

‌Regular maintenance‌

The lubricating oil needs to be replaced after 100 hours of first use, and then every 500 hours.

If the pump is not used for a long time, the pump body needs to be completely disassembled, the water needs to be wiped off, and anti-rust grease needs to be applied.

‌Fault prevention‌

Pay attention to the wear of the floating sleeve (the clearance needs to be replaced if it exceeds 0.20mm) to avoid efficiency loss or overheating due to internal leakage.

Check the aging of the oil seal regularly, and replace the failed rubber seals in time to prevent the high and low pressure chambers from flowing through.

3. Handling of special working conditions

‌Oil suction difficulty troubleshooting‌: Check whether the welds and O-rings of the oil inlet pipeline are leaking, and whether the oil level meets the standard.

‌Heavy load operation adaptation‌: Give priority to models with stronger pressure resistance (such as the AZPF-11 series) to ensure stable output under high pressure conditions.
