SKF MKU2-BW3-200003J Lubrication Unit

The SKF MKU2-BW3-200003J Lubrication Unit is an electrically driven gear pump module designed for single-line lubrication systems in SKF MonoFlex central lubrication installations, delivering metered lubricant to piston distributors. It operates from 200 V AC and provides a metering rate of 0.2 L/min (200 cm3/min) at system pressures up to 2.7 MPa, enabling reliable lubrication across multiple points. The unit includes pre-installed pressure-regulating and relief valves, and can be equipped with an optional pressure gauge, fill-level monitoring, and an integrated pressure switch for real-time feedback; control is external via the machine control system or an integrated control unit, with a push-button option to initiate interim lubrication as needed. Main functions are integrated into the lid, and a protective plastic cap guards electrical components from dirt and dust, ensuring durability in industrial environments. Within the MKU family, metering quantities are offered in 100, 200, and 500 cm3/min variants, with the BW3-200003J design corresponding to the 0.2 L/min option, and lubricants typically being mineral oil or synthetic oil with a viscosity range of roughly 20 to 1500 mm2/s. Operating temperature for these units is generally specified from +10 to +40 °C, making them suitable for standard industrial environments and straightforward integration with SKF piston distributors and central lubrication layouts.
