The AX line of pumps and motors developed by Bucher Hydraulics is based on a revolutionary new hydraulics concept and is of high value for electrified machinery. First, because of its efficiency: Battery capacity is expensive. To save battery capacity, the efficiency of electrical machinery must be as high as possible. The efficiency of the new AX pumps and motors is a high 94%, which is 5 to 10% better than the products available on the market up until now. Power dissipation can be reduced by up to 50%, which can be transferred 1:1 to the saving of battery capacity.
Second, the AX can also operate at very low speeds and high loads without wear and tear and, thanks to its high starting efficiency of 99%, reduces the ripple effect by 80%. This results in very slow, uniform and precise movements, as required by modern hydraulic motors.
Third because it reduces noise: In contrast to combustion engines, electric drives are quiet. So the hydraulic components they use should also be quiet, which the AX line is with around 70 decibels.
Moreover, these pumps and motors are made almost exclusively of cast iron and steel and contain no components made of non-ferrous metals. They can be completely and above all easily recycled, which is not the case with comparable conventional pumps and motors.
