Description

Possible Applications
This mounting flange is engineered for secure mechanical integration of hydraulic pumps within heavy-duty industrial machinery and mobile working equipment. Typical installations include axial piston units driven on injection molding machines, metal stamping presses, and industrial power units where robust face-mounting is required to withstand high continuous torque and cyclic pressure loads. In the mobile sector, it is frequently utilized on agricultural tractors, forestry harvesters, and construction excavators to couple hydraulic pumps directly to auxiliary diesel engine power take-off ports. The rigid four-hole architecture ensures precise coaxial alignment between the prime mover and the pump shaft, effectively minimizing vibration and mitigating mechanical fatigue during rigorous continuous-duty operations.
