Hydraulic Power Unit with Sperry Vickers Valve and 5 kW Motor

Description

This used hydraulic power unit is built on a robust industrial skid and features a Sperry Vickers directional control valve for precise flow regulation and pressure control. It includes a compact gear pump system and is powered by a CEI-branded asynchronous three-phase electric motor. The motor delivers 5 kW of continuous power at 1435 RPM, operating at 380V / 50 Hz. The entire assembly is suitable for high-reliability hydraulic applications in industrial environments such as presses, lifting systems, and hydraulic drives.
