DDB type electric grease pump is a compact structure, excellent performance, high output pressure electric plunger lubrication pump, up to 24 pump units at the same time, and can be arbitrarily chosen..Equipped with an independent relief valve to prevent pressure overload of the pump unit, and can complete the centralized overflow return function in SLR, each oil outlet has its own distributor to distribute the grease proportionally to each lubrication point through the CU.In the progressive lubrication system, the distributor of each oil outlet forms an independent lubrication system, and under the process controller, the grease can be delivered to each lubrication point at regular and quantitative intervals.If equipped with an oil level switch, it can achieve a low oil level alarm, and the motor protective cover can prevent dust and rain.The pump is widely used in engineering, transportation, mining, forging, steel, construction and other machinery.
