Electric grease pump JS

follower plate

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. Operation The motor drives gears to reduce speed and actuates a piston that moves back and forth by means of a crank. With the movement, oil/grease is pulled into an opening at the base of the pump and flows out past a check valve into the lubrication lines. Fixed quantities of oil or grease can be delivered to each lubricating point at predetermined times when used with available programmed controller (sold separately). A relief valve is provided inside the pump to effectively protect lubrication system.
