Answer 2

Answer:

Centrifugal pump start up procedure

Open the suction valve.

Open any recirculation or cooling lines.

Fully close or partially open the discharge valve, depending on system conditions.

Start the driver.

Slowly open the discharge valve until the pump reaches the desired flow.

Explanation:

The shutdown procedure is the reverse of the startup procedure:

Gradually close the discharge valve. If there is no discharge valve and the pump has a rotational speed governor, then gradually decrease the rotational speed of the pump motors until the pump is no longer rotating.

Turn off the pump's power supply.
