LT-A2FW6.1 Series (28-180ml/R)
The LT-A2FW6.1 constant displacement hydraulic pumps/motors are suitable for both open-circuit and closed-circuit hydraulic transmission systems. Featuring a fixed displacement design, output speed is proportional to input flow, while output torque increases with system pressure differential. This series is well suited for hydraulic drive systems with stable operating conditions and high requirements for efficiency and reliability.
