A2F Bent Axis Pumps

Product Overview

A2F Bent Axis Pumps is fixed displacement bent-axis axial piston unit, it can work either as pump or hydraulic motor, suitable for both open and closed hydraulic circuit. It transfers rotary mechanical energy into high-pressure hydraulic power, serving as robust power component for heavy-duty Machine. Featuring bent-axis tapered piston structure and spherical valve plate, A2F delivers high efficiency, outstanding pressure resistance and strong anti-shock performance, widely used in hydrostatic transmission systems for mobile and industrial hydraulics.

Technical Specifications

- Displacement range: 10,12,23,28,45,55,63,80,107,125,160,200,250,355,500 cm³/rev

- Nominal pressure: 350 bar

- Peak pressure: 400~450 bar (depends on displacement size)

- Structure: Bent-axis fixed displacement axial piston, tilt angle 20° / 25°

- Shaft options: Keyed shaft, splined shaft

- Mounting: ISO standard flange

- Rotation: Clockwise / Counter-clockwise optional

- Dual usage: Can be applied as pump or hydraulic motor

- Good compatibility with mineral oil, optional version for fire-resistant hydraulic fluid

Working Principle

The drive shaft and cylinder block are arranged at a fixed bent angle. When the drive shaft rotates, tapered pistons rotate together with cylinder block and perform reciprocating axial movement inside cylinder bores. Volume expansion creates oil suction; volume compression realizes high-pressure oil discharge. Since the tilt angle is fixed, displacement remains constant. The output flow is proportional to rotating speed. The spherical distribution plate achieves self-centering, reduces friction loss and improves volumetric efficiency of the hydraulic system. When used as a motor, high-pressure oil pushes pistons to generate torque and drive the shaft rotation.

Key Features

1. Bent-axis design, ultra-high volumetric & total efficiency, low heat generation under continuous high pressure

2. Dual function: works as pump or hydraulic motor, flexible for hydrostatic transmission

3. Spherical valve plate self-centering structure, low noise, low friction and stable operation

4. Reinforced heavy-duty bearing group, drive shaft can bear radial load, excellent shock & vibration resistance

5. Compact and high power density, small footprint for limited installation space on Machine

6. Fixed displacement simple structure, less vulnerable parts, long service life and easy maintenance

7. ISO standard mounting flange, interchangeable with A6V series motor, convenient system matching

Application

- Construction machinery: concrete pump truck, mobile crane, road roller, drilling rig

- Mining equipment: underground mining vehicle, rock drill, mining loader

- Marine & offshore: deck winch, marine hydraulic power pack

- Metallurgical industry: hydraulic press, metal forming equipment

- Special mobile machinery: forestry machine, heavy transport vehicle, hydrostatic drive system
