The Multilube pumping unit is especially designed for heavy machines and equipments. It has a very compact size, but still includes all key components and functions required for a lubrication pumping unit as control unit, pump, reservoir, directional valve and pressure monitor. The Multilube pumping unit is compatible with all oil and grease metering devices used in single-line, dual-line and progressive lubrication systems. As one of the built-in features there is a heating device which enables also an operation in extremely cold and demanding environments. Depending on application requirements, auxiliary equipment, such as sliding surface nozzles and lubrication brushes, can be used.
