Advantages and features of Rexroth gear pumps

‌High-efficiency design‌

Using high-quality materials and advanced manufacturing processes, it has high efficiency and low energy consumption, and can adapt to the delivery needs of media with different viscosities.

The flow rate covers a range from 5 cm³/rev to large displacement (such as the AZPF series).

The nominal pressure reaches 280 bar, supporting high-pressure stable output, meeting the needs of heavy-load scenarios such as hydraulic systems and metallurgical equipment.

‌Structural reliability and low maintenance cost‌

The structure is simple and compact, and the gears and sliding bearings are designed to be wear-resistant and corrosion-resistant, extending the service life while reducing maintenance frequency and cost.

The modular combination design supports multi-pump linkage, which facilitates the flexible configuration and expansion of complex systems.

‌Environmental adaptability and noise reduction performance‌

Adopting low-noise tooth shape and vibration reduction technology, it has low noise (≤20 decibels) and low vibration during operation, which is suitable for scenarios with strict requirements on the working environment.

It can transport lubricating oil, hydraulic oil, fuel and corrosive liquids. The material has strong corrosion resistance and is suitable for special media such as water-based and emulsions.

Precautions for use

‌Installation and commissioning‌

During cold installation, hinge supports must be set on the piping to prevent displacement of the pipeline after heating; the coupling must be heat-aligned after the pump body is heated to avoid additional torque damaging the equipment.

Before the first start, water (or slurry) must be poured in and the motor direction must be checked to ensure that there is no abnormal sound before formal operation.

‌Operation monitoring and safety protection‌

An interlocking alarm device must be installed at the outlet pressure measurement point to prevent pipeline blockage from causing overload damage to the pump body; the speed must be gradually increased at the initial start to avoid sudden pressure changes that impact the bearings.

Regularly check the lubricating oil level and replace or replenish it in time; the medium must be emptied after long-term disuse to prevent internal scaling or corrosion.

‌Maintenance and life management‌

Regularly replace bearings and melt filters to avoid long-term high-pressure operation; the internal parts must be removed during cleaning to prevent foreign matter from entering the pump body.

Control the pump jacket temperature to be slightly lower than the pipeline heat medium temperature to prevent melt degradation, and improve the bearing capacity by optimizing the bearing area temperature.

The above characteristics and operating specifications combine the core advantages and key maintenance points of Rexroth gear pumps in industrial applications, and are suitable for complex working conditions in the fields of machinery manufacturing, shipbuilding, metallurgy, etc.
