Nachi #VDC-1B-3A3-Q13-U-6064C, Variable Vane Pump

Used in hydraulic power units for CNC machine tools, industrial machinery, and automated manufacturing systems, the Nachi VDC-1B-3A3-Q13-U-6064C is a variable volume vane pump manufactured by Nachi-Fujikoshi Corp. of Japan. The VDC series is engineered for high-efficiency, stable high-pressure hydraulic operation and is widely recognized in the machine tool industry as a reliable source of variable-displacement flow. The 3A3 displacement code within the VDC-1B family indicates a higher flow capacity relative to the smaller 2A3 variants, making this unit appropriate for applications requiring greater volumetric output. The pump features a four-bolt SAE flange mounting face and a keyed output shaft visible in the photos. An integral pressure-compensated control mechanism with external adjustment capability is present on the pump body. Manufacturer designation is VDC-1B-3A3-Q13-U-6064C as stamped on the nameplate, with manufacturing number 3805S indicated. The unit is manufactured by Nachi-Fujikoshi Corp. and bears the NP27 designation on the plate. Nachi VDC series pumps are commonly found in Mazak, Okuma, Mori Seiki, and similar CNC machining center hydraulic systems. The pump ships as a standalone unit without motor, coupling, or reservoir.
