The EPG series of electric lubrication pump is controlled by a DC motor. Its displacement is linearly related to the motor speed,making it suitable for complex and variable working conditions. Driven by a brushless DC motor and used with a control unit, the lubrication pump is designed f or single-line centralized lubrication systems. When lubricant should be delivered to lubrication parts, the motor and solenoid valve are energized, and the pump begins to work. When the grease injector completes the grease filling operation and the pressure of the system reaches the set value, the pressure switch transmits the signal to the
control unit, then the control unit cuts off the power supply of the motor and the solenoid valve, and the whole sys tem relieves pressure and enters the next lubrication cycle.
