Constant Pump/Motor
LT-A2F Series (23-107ml/R)
The LT-A2F bent-axis constant motors/pumps are reversible hydraulic units. By selecting different valve plates and rear covers, the same motor can be configured either as a constant displacement pump or a constant displacement motor, making it suitable for both open-circuit and closed-circuit hydraulic transmission systems.
With a fixed displacement design, motor output speed is proportional to input flow, while output torque increases with system pressure differential. This constant pump/motor is well suited for stable operating conditions and hydraulic systems with high reliability requirements.
