How to prevent the stroke positioning motor of the metering pump from burning out?

1. Remove the 4 screws that secure the pump head. The screw is located on the back of the metering pump.

2. Check if the drain pipe is installed and the drain valve is closed? The discharge valve needs to be opened during the liquid introduction stage of the metering pump. Note: Not all metering pumps have drain valves.

3. After the diaphragm is installed and the leakage discharge hole on the back plate is placed in a vertical position, install the pump head. Ensure that the suction valve is aligned with the leakage discharge hole, and the screws on the hydraulic end are aligned with the corresponding 4 holes.

5) Has the flow rate of the hydraulic metering pump decreased or become inaccurate?

1. Unscrew the vent valve in the three valves.

2. Fully replenish the oil through the oil replenishment valve.
