Showa LCB321C Lubrication Pump

Showa's LCB321C Lubrication Pump is a compact, intermittent metering unit in the LCB3 family designed to deliver precise lubricant volumes to centralized lubrication systems. Inside the unit, the MLB01W1 pump drives controlled discharge to lubrication points, enabling repeatable lubrication across automation lines. For the LCB3 platform, discharge per cycle is 0.1 L at 50 Hz and 0.12 L at 60 Hz, with a discharge pressure up to 1.2 MPa (12 bar). The tank capacity is 3.4 L, with an effective usable volume of about 2 L, making it suitable for short-run or multi-point lubrication tasks. Electrical variants cover 100 V or 120 V at 50/60 Hz, with current draws ranging from approximately 0.6 A to 1.5 A depending on the configuration. The system supports Showa’s distribution approach, where oil from the pump can be routed to lubrication points by introducing resistance at junctions or points, and can be paired with a YT intermittent timer (2–192 minutes) to govern discharge intervals. The LCB321C(B) designation identifies a specific configuration within the LCB3 lineup; exact wiring, timer options, and fittings vary by SKU and region. This pump is used where precise, repeatable lubrication is required in automated equipment and robotic tooling, and it aligns with Showa’s lubrication-system charts for proportional distribution.
