Showa LCB4 7448-1 Lubrication Oil Pump

The Showa LCB4 7448-1 Lubrication Oil Pump is a compact central lubrication unit designed to meter precise quantities of oil from a single reservoir to multiple lubrication points. This 200 V variant, identified by the 7448 code, uses the MLB01W2 pump module and is supplied without an IC timer, with optional accessories such as a pressure switch, pressure gauge, or float switch available to tailor monitoring and control. The basic configuration typically pairs a 2 L tank (effective capacity about 1.3 L) but the LCB4 family also includes versions with larger 6 L reservoirs for longer service intervals. The pump delivers approximately 0.1–0.12 L per discharge cycle at 50–60 Hz and can achieve discharge pressures up to about 1.2 MPa (12 bar). Current draw for the 200 V setup varies by options and wiring, generally falling within the 0.6–1.5 A range. Designed for industrial use, the LCB4 serves as the volumetric source in Showa’s centralized lubrication systems, suitable for applications such as machinery lines, presses, and other equipment requiring reliable, metered oil delivery to multiple lubrication points. The 7448-1 designation specifically identifies the 200 V version within the LCB4 lineup, enabling integration with compatible tanks and distribution components to form a complete lubrication loop.
