01Main advantages
02High energy efficiency: the swashplate design precisely regulates oil flow according to demand, reducing wasted power and fuel consumption.
03Ideal power-to-weight balance: the pump has a compact design and high power density, making it easy to install in limited mounting spaces.
04Wide range of control options: supports pressure and flow control (DFR/DFR1), constant power control, and electro-proportional control (EP).
05Low noise and vibration: special pre-compression technology reduces pressure pulsation by up to 50%, ensuring quiet system operation in the operator cabin.
06Long service life: durable bearings and an optimized lubrication system withstand high radial and axial loads, minimizing maintenance costs.
07High self-priming speed: excellent suction characteristics at high speeds without the need for an additional auxiliary pump.
