Hydraulic power units


DESCRIPTION

A hydraulic power unit is a group of different components that generate mechanical energy converted into pressurisation of the oil in a hydraulic circuit. Their main function is to apply the hydraulic pressure required to control the motion of cylinders, hydraulic motors or other parts of a specific system.

Duplomatic produces power units for a variety of pressure ranges and flow rates, capacities, materials and types of fluid compatibility. Hydraulic power units are designed with modern 3D systems with multiple interfaces and FEM simulation systems and are produced entirely in Italy at our dedicated facility in Lainate.

Duplomatic offers all of the necessary expertise (fluid dynamics, functional, electrical and build-related) to create the most appropriate solution for the requested application, establishing ongoing dialogue with our customers’ technical departments.
