A2F10R4P4 A2F Series High Pressure Axial Piston Pump

As a professional China factory manufacturer and reliable supplier of high-performance industrial hydraulic piston pumps, Hengmeisi focuses on the R&D and production of standard interchangeable A2F10R4P4 A2F Series High Pressure Axial Piston Pump is a hot-selling high-precision axial piston pump. Wuhan Hengmeisi Hydraulic Co., Ltd. Plunger pump A2F10R4P4 series hydraulic gear pumps are high-performance, reliable solutions designed to replace and match the original specifications perfectly. All of Hengmeisi products are completely equivalent and interchangeable with the original Rexroth A2F series pumps, offering the same fit, function, and performance at a competitive factory-direct price. Tailored for high-speed and high-pressure hydraulic transmission scenarios, this A2F10R4P4 piston pump abandons the structural limitations of ordinary hydraulic pumps, adopting a mature oblique shaft fixed displacement design to achieve stable power output in both open and closed hydraulic circuits.

The A2F10R4P4 breaks through the performance bottlenecks of ordinary low-pressure hydraulic pumps on the market. Most conventional hydraulic pumps cannot withstand ultra-high pressure and high-speed cyclic operation, and are prone to severe vibration, pressure attenuation and rapid component aging. In contrast, the A2F series piston pump represented by A2F10R4P4 adopts spherical flow distribution and self-aligning structure, with low running resistance and high transmission efficiency. It can stably adapt to long-term high-speed operation and instantaneous high-pressure impact, maintaining consistent working performance without failure. Every A2F10R4P4 pump produced by Hengmeisi undergoes strict factory pressure testing, high-speed aging testing and sealing detection, ensuring 100% interchangeability with original imported pumps and stable quality for long-term industrial application.

Unique Core Product Advantages

1. 100% Interchangeable with Original Rexroth Pumps

The biggest advantage of the A2F10R4P4 A2F Series High Pressure Axial Piston Pump is its full compatibility and interchangeability with the original Rexroth A2F series products. It completely replicates the original installation size, shaft diameter, port position and internal assembly parameters, requiring no modification to the original equipment during replacement. The fit, operating function and output performance are fully consistent with imported pumps, helping global customers quickly replace aging and damaged original pumps without changing the hydraulic system layout. While ensuring zero difference in use effect, it greatly reduces equipment procurement and maintenance costs.

2. Oblique Shaft Structure, High Speed & High Pressure Resistance

Different from common swash plate piston pumps, the A2F10R4P4 adopts a professional oblique shaft transmission structure, which has stronger structural rigidity and impact resistance. The pump supports ultra-high-speed operation up to 5000r/min, and the rated working pressure reaches 350bar with a peak pressure of 400bar, fully meeting the ultra-high pressure demand of heavy-duty hydraulic systems. The unique spherical oil distribution design enables automatic center alignment during operation, reducing friction loss between the cylinder body and the oil distribution plate, effectively avoiding pressure fluctuation and power loss, and realizing stable high-power hydraulic output.

3. High Transmission Efficiency & Low Energy Consumption

Optimized with precision internal matching clearance and high-precision grinding piston assembly, the A2F10R4P4 effectively suppresses internal leakage and mechanical friction loss. Its overall volumetric efficiency is as high as 95%, and the mechanical transmission efficiency is far higher than that of ordinary gear pumps and vane pumps. Even under long-term high-speed and high-pressure continuous operation, it will not produce obvious efficiency attenuation. It can convert motor power into hydraulic power to the greatest extent, reduce invalid energy loss of the system, and achieve long-term energy-saving and efficient operation of industrial equipment.

4. Strong Environmental Adaptability & Ultra-long Service Life

The core components of the A2F10R4P4 such as cylinder body, piston and distribution plate are made of high-strength wear-resistant alloy materials, processed through vacuum heat treatment and precision finishing, with excellent wear resistance and pressure impact resistance. The imported high-temperature and oil-resistant sealing components are compatible with various industrial hydraulic media, adapting to harsh working environments such as high temperature, high load and continuous operation. The whole pump has low failure rate and strong anti-fatigue ability, which can effectively extend the service life of hydraulic equipment and reduce downtime loss for industrial production.

Product Structure & Working Principle

The A2F10R4P4 axial piston pump adopts a mature and reliable oblique shaft fixed displacement structure, mainly composed of drive shaft, inclined shaft mechanism, piston assembly, high-strength cylinder body, spherical oil distribution plate, rolling bearing assembly and high-performance sealing system. The overall structure is compact, precise and sturdy, with strong pressure resistance and operational stability:

1. Oblique Shaft Transmission Mechanism: Different from traditional swash plate pumps, the A2F10R4P4 uses an inclined shaft to drive the piston for reciprocating motion. The structural stress is more uniform, which can bear higher speed and pressure load, avoiding structural deformation and failure under extreme working conditions.

2. Spherical Self-aligning Oil Distribution Structure: The built-in spherical oil distribution plate can automatically align with the cylinder body during high-speed operation, keeping the fitting gap uniform and stable. It effectively solves the problem of poor sealing and large leakage caused by eccentric wear of traditional oil distribution structures, ensuring stable flow and pressure output.

3. High-precision Piston Assembly: Multiple groups of alloy steel pistons are arranged evenly and circumferentially, with precise matching clearance. The pistons move smoothly without jamming, realizing continuous and stable oil suction and pressure discharge, and ensuring high-efficiency hydraulic power transmission.

4. Integrated Sealing & Protection System: Multi-channel combined sealing design is adopted at the shaft end, oil port and assembly gap. It can resist high-pressure impact and high-temperature corrosion, completely prevent internal hydraulic oil leakage and external impurity infiltration, and protect internal precision components for long-term stable operation.
