DR Series electric lubrication pump is a gear pump.The pump has a level switch. According to different uses, pressure switch can also be configured, connected to the programmer on the pump. It can also be connected to the user's main device program controller system，Can achieve the oil level in the oil tank，oil pressure monitoring system，as well as the equip- ment lubrication cycle.

It can form a PDI lubrication system with a quantitative oil injector (PDI) to perform quantitative oil injection lubrication on each lubrication point; it can also form an SLR lubrication system with a metering part (MU) to perform proportional oil lubrica- tion on each lubrication point.Widely used in the centralized lubrication system of various equipment such as machine tools, plastic machinery, textile machinery.
