Hydraulic pump supports are essential structural components designed to ensure a rigid, secure, and precisely aligned mechanical connection between the drive unit and the hydraulic pump. Engineered to absorb torsional vibrations and compensate for minor shaft misalignments, these components help minimize radial and axial loads on the shaft. This structural isolation prevents abnormal wear of pump assemblies, protecting bearings and sealing systems under all operating conditions.
The available range meets a wide variety of system requirements while ensuring maximum reliability. For hydraulic circuits using Group 3 pumps, high-strength solutions such as the Borelli Cast Iron Pump Support Gr. 3 Series 25610-24 ensure durability, while the Borelli Pump Support with SAE B 2-Bolt Flange Gr. 3 Series 25608 is ideal for American-standard mounting interfaces. Systems with intermediate pump displacements require components designed to withstand specific pressure peaks. In this category, the Borelli Pump Support Gr. 3.5 Series 25405-25605 ensures high torsional stability. Finally, for heavy-duty installations with large-displacement pumps, the Borelli Universal Pump Support Gr. 4 Series 25609 offers exceptional mounting versatility combined with maximum dynamic load absorption capacity.
The use of these high-strength metal alloy supports is essential in the assembly of industrial hydraulic power units and mobile hydraulic systems, from earthmoving equipment to hydraulic presses. Their installation eliminates the risk of drive shaft deflection, significantly reducing machine downtime caused by premature coupling hub wear. The selected products also provide a substantial reduction in noise emissions and simplify maintenance operations thanks to standardized mounting dimensions and machining tolerances measured to hundredths of a millimeter.
