01Main technical advantages
02Bi-directional rotation: operates both clockwise and counterclockwise. This eliminates the risk of pump damage in case of incorrect rotation direction and reduces spare-parts inventory requirements, since one pump replaces two different models.
03Standard 4-bolt ISO mount: equipped with an international ISO-standard 4-hole flange. It installs easily on PTOs and gearboxes without expensive adapters.
04Durable cast-iron housing: made from high-quality cast iron. It withstands heavy-duty conditions, high vibration, and continuous working pressure, often from 250 to 300 bar depending on the specific model.
05Simple system architecture: fluid-flow direction can be changed by reversing mechanical rotation direction. This reduces the need for additional directional valves in the system.
06Compact design: optimized dimensions are ideal for installation in narrow spaces under truck chassis, on dump trucks, and on recovery vehicles.
07High efficiency: delivers accurate volumetric flow per revolution, minimizing internal energy losses and saving fuel.
