Product Features
The TFA4V(T)G Series is a variable displacement hydraulic pump with a swashplate design for closed-circuit hydrostatic transmission. This hydraulic piston pump delivers smooth, infinitely variable flow in proportion to drive speed and displacement, with stable flow-direction changes through neutral. Cartridge-type high-pressure relief valves help protect the pump and motor from overload. It is suitable for construction, agricultural, mining, material-handling and other mobile or industrial hydraulic equipment.
