How to start a centrifugal pump
WebPrinciple: Centrifugal pumps operate by using the rotation of the impeller to generate centrifugal motion of water. Before starting the water pump, it is necessary to fill the pump casing and suction pipe with water. Then, start the electric motor to push the impeller and water to perform high-speed running fitness exercise. WebFor pumps 500 gals/min or larger use semi-automatic manual valves at the discharge that are controlled to open gradually when starting the pump. This will avoid water hammer during the initial start and damage to the piping …
