Centrifugal pumps are widely used in various industries for the transfer of fluids. One common practice in operating centrifugal pumps is to start the pump with the discharge valve closed. This may seem counterintuitive to some, but there are valid reasons behind this practice.

>If you start the pump discharge valve closed, it means no discharge head minimum resistance to the pump and minimum current drawn. Even though current taken during startup is more than normal, by closing discharge valve you can avoid extra load on the pump. >If you have a

Centrifugal Pump Discharge Valve Closed

When a centrifugal pump is started with the discharge valve closed, it reduces the initial power demand on the pump motor. This is because when the discharge valve is closed, there is no flow of fluid through the pump, which means less resistance for the pump to overcome. As a result, the pump motor does not have to work as hard to start the pump.

Pump Discharge Valve Closed

Another reason for starting the pump with the discharge valve closed is to prevent damage to the pump. When a centrifugal pump is started with the discharge valve open, it can cause a surge of fluid through the pump. This sudden surge of fluid can create water hammer, which can damage the pump impeller, casing, and other components.

Discharge Valve Closed When Starting Pump

By keeping the discharge valve closed when starting the pump, it allows the pump to gradually build up pressure within the system. This gradual increase in pressure helps to prevent water hammer and ensures a smooth start-up of the pump. Once the pump is up and running smoothly, the discharge valve can be slowly opened to allow the fluid to flow through the system.

By starting the pump with the discharge valve closed the power demand made by the pump on the pump motor is kept to a very minimum. After the pump has started and the …

The submersible design of our pumps means that they are not only more efficient but also safer to operate. The pump is located below the fluid level, which eliminates the risk of cavitation and dry running. The pumps are also .
