Overview
The TAIFENG TFA7VO/11 Series is an axial piston variable pump designed for open-circuit hydraulic systems. Its swashplate design allows continuous flow adjustment based on drive speed and displacement, matching output to changing load requirements. It features infinitely variable flow control, quick response, multiple control options (constant power, constant pressure, electric-proportional), low noise, and a through-drive option. With displacements from 28 to 250 ml/r and a 350 bar nominal pressure (400 bar maximum), it is ideal for mobile machinery, agricultural equipment, and industrial hydraulic power units.

Key Features
Infinitely variable flow adjustment through swashplate angle control.
Quick response for smooth and responsive actuator operation.
Multiple control options, including constant power, constant pressure and electric-proportional displacement control.
Low noise and excellent suction performance for reliable system operation.
Through-drive option for multiple-pump hydraulic systems.

Typical Applications
Suitable for mobile machinery (such as excavators, cranes, and loaders), agricultural equipment (such as tractors and harvesters), industrial hydraulic power units, and other open-circuit systems requiring flexible flow control. Its wide displacement range and multiple control modes make it adaptable to varying duty cycles, while the through-drive option enables multi-pump configurations for complex hydraulic circuits.
