Changzhou LangO Machinery and Technology Co.,Ltd is a professional lubrication pump manufacturer and exporter in china, that is concerned with the design, development and production of lubrication equipment.


DRB-L series motor driven lubricating pump applies to the dual line grease concentrated lubricating  system with more lubricating points, a broad range of distribution and high frequency of grease feeding. It supplies and delivers lubricating grease to each lubricating point through a dual line distributor, which can meet the needs of various machinery equipment and is especially suitable for large-sized units and production lines.

This series motor driven lubricating pump can constitute dual line ring-shape concentrated lubricating system, i.e. the main pipelines of the system are distributed in the shape of ring. The hydraulic reversal valve is controlled by the system pressure at the end of the main pipelines of the returned lubricating pump, making the two main pipelines supply and deliver lubricating grease alternatively. See the provisions in the External Appearance Drawing and Dimension Table. It can also constitute dual line terminal type concentrated lubricating system, i.e. the electromagnetic reversal valve is controlled by the pressure control valve at the end of the main pipelines of the returned lubricating pump, making the two main pipelines supply and deliver lubricating grease alternatively. See the provisions in the External Appearance Drawing and Dimension Table.

This series motor driven lubricating pump is equipped with double-piston mechanism which is reliable in running. The speed reduction mechanism is located in the pump body with a compact structure and a small area which may realize automated control when being matched with an electric control cabinet.

Working principle

This series motor driven lubricating pump is composed of piston pump, grease conservator, reversal valve, motor and so on. Driven by the motor, piston pump absorbs grease from the conservator, feeds to reversal valve and alternatively delivers grease from two grease outlets through the reversal valve. When lubricating grease is delivered from a grease outlet, the other grease outlet is connected to the conservator for unloading.

Ring-shape motor driven lubricating pump is equipped with hydraulic reversal valve with four interfaces. Two main grease supply pipelines are externally connected by which a grease returning pipeline is led. It relies on the pressure of grease in the grease returning pipeline to push reversing of reversal valve.

Terminal type motor driven lubricating pump is equipped with hydraulic reversal valve with two interfaces. Two main grease supply pipelines are externally connected. Reversing grease supply is achieved based on the power on and power off of electromagnet.

Please see the user manual for the working principle of reversal valve of piston pump.
