A2F fixed displacement axial piston pump

A2F Fixed Pump / MotorAxial Piston · Bent Axis

PRODUCT OVERVIEW

Overview

Axial piston unit of bent axis design with fixed displacement, for use as either pump or motor in hydrostatic drives, in open or closed circuit. As a pump, flow is proportional to drive speed and displacement; as a motor, output speed is proportional to flow and inversely proportional to displacement.

Pump Mode

Flow is proportional to drive speed and displacement, ideal for stable fixed-delivery oil supply and transmission.

Q ∝ n × Vg

Motor Mode

Output speed is proportional to flow and inversely proportional to displacement; torque rises with the pressure drop between high and low pressure sides.

n ∝ Q ÷ Vg · T ∝ Δp

Circuit Application

Suitable for open or closed circuits, compatible with fire-resistant fluids for a wide range of hydrostatic drive applications.

Open / Closed Circuit

SPECIAL FEATURES

Product Features

A well-proven rotary group and bearing design balancing efficiency, service life and installation convenience.

Spherical Control Area

High-performance rotary group with well-proven spherical control area — self-centering, low peripheral speed, high efficiency.

Robust Rolling Bearings

Ball and roller bearings work together to ensure a long service life and reduced maintenance.

Radial Load on Shaft

The drive shaft is capable of adopting radial loading, adaptable to a variety of mounting and transmission setups.

ISO Mounting Flange

Uniform ISO mounting flange for fixed pumps/motors and variable motors from size 55 for easy interchange and standardization.

Fire-Resistant Fluids

May be used in conjunction with fire-resistant fluids for high-temperature and fire-safety applications.

Low Noise

Optimized structure and port design deliver low-noise operation for a better working environment.
