Lubrication pump DRB-L equals the U type of electric lubrication pump is used for for dual-line central lubrication system which requires for multi-lubrication point in a wild range of lubrication line and high grease feeding frequency. The medium of grease is pressurized by lubrication pump DRB-L and lubricating the point through dual line distributors, which will able to meet the different needs of various machinery and equipment, this lubrication pump is mostly equipped in a big machinery group or production line.
The DRB series of electric lubrication pump can is available to become dual line loop central lubrication system, for example, the main supplying line components annular configuration, the hydraulic directional valve is controlled by return pressure at the end of main supplying line, in order the centralized lubrication systems lubricates grease to each lubricating point alternately. The dual line end type of central lubrication system is available as well, the end pressure of main supplying line controls the solenoid directional valve to feed the grease or oil to lubricating point alternatively.
The feature of lubrication pump DRB series is reliable working operation, compact structure of reduction mechanism in pump, and automatically control is available if equipped with electric terminal box.
The Working Principle Of Lubrication Pump DRB-L, Electric Lubrication Pump U Type:
– The pump consists of piston pump, grease reservoir, directional valve, electric driven motor.
– The grease is pressurized from reservoir to directional valve, and the directional valve transfers the grease alternatively through two outlets, when one outlet feeds grease, the other connects to reservoir and unloading pressure.
There are two kinds of function as per Loop type and End type system:
– Loop type of lubrication pump DRB consists of 4 connectors. The directional valve is pushed by grease in returned pipe to feed the grease or oil.
– End type of electric lubrication pump DRB consists of 2 connectors. There are 2 main grease supplying pipes connected to feed the grease or oil by solenoid directional valve.
