The JS/JSP Series Lubricator motorized oil/grease pumps are piston discharge pumps driven by DC motor, controlled by a controller or PLC (not included). These lubricators are compact and have a large output flow. Pumps have a relief valve to help protect the lubrication system. The JS can be used in series progressive lubricating systems and in single line resistance systems (SLR). The JSP can be used in positive displacement injector (PDI) systems. Either can be used for light industries, forging machinery, etc.
