Before starting, the discharge valve and related valves on the discharge pipeline must be opened.

Start the motor and observe the operation of the pump to ensure that there is no abnormal vibration and noise.

②Operation:

During operation, it is forbidden to close the discharge valve to avoid damaging the pump or pipeline, or even burning the motor.

Check the lubrication of the pump regularly to ensure that all parts are well lubricated.

By observing the instrument and listening to the sound, keep track of the operation of the pump at any time.

③Flow regulation:

The flow regulation of the double pump is usually achieved through the bypass valve. According to actual needs, adjust the opening degree of the bypass valve to achieve the required flow and pressure.
