Electric grease pump EAP series

EAP lubricating units are designed for convenient portability where multiple lubrication points are serviced utilizing the same type and grade of lubricant. PRODUCT CHARACTERISTICS Mobile lubricating pump Discharge max. 130 cm3/min Lubricant: oil, grease Surface signal grey RAL 7004 incl. grease gun, flex. hose, coupling etc. FUNCTION EAP 110 Motor rotation is converted into linear motion by means of a spur gear and crank mechanism. This, in turn, drives the piston. Simultaneously, an agitator blade in the lubricant tank operates to assure lubricant delivery to the pump intake and pressure chamber. Care should be taken when filling the reservoir to avoid introduction of air pockets. A pressure relief valve circuit is incorporated into the unit which returns lubricant to the tank whenever the grease gun is closed, or when backpressure encountered at the point of application is extreme. EAP 130 Model EAP130 incorporates two high-pressure pump assemblies which operate independently of each other. Each unit consists of a pump, double acting non-return valve and a pressure relief valve. Output volume of the two units is combined into a single outlet via external conection. The maximum working pressure of each independent pump assembly is determined by its respective relief valve. Therefore, the maximum working pressure of the combined units is determined by the unit having the lowest value relief valve. Whenever the grease gun is closed, lubricant contained within the high-pressure chamber is diverted back to the tank. Therefore, when the gun is closed, the pump should be turned off whenever possible to ensure unit longevity.
