Chiba DPB-28 8 Position Oil Distribution Piston

The Chiba DPB-28 8-position oil distribution piston is a volumetric piston distributor used in centralized lubrication systems to deliver fixed oil volumes to eight lubrication points with each pump stroke. It provides eight outlet ports and offers selectable discharge volumes of 0.1 cm3, 0.2 cm3, 0.4 cm3, or 0.6 cm3 per stroke, enabling precise dosing across multiple points from a single device. Designed to operate under pump discharge pressures from 8 to 30 kgf/cm2, it uses standard metric threading for connections, including M12x1 and M8x1. In DPB-28L/DPB-28 literature, body dimensions are documented as approximately 102 mm by 148 mm, reflecting a compact footprint for manifold installation. The DPB-28 is used in machine tools, automation equipment, and other industrial lubrication applications that require metered delivery to multiple outlets, relying on the pump’s discharge pressure to push oil through each port and dispense a pre-measured volume to every lubrication point.
