Centrifugal pump has more weight due to a given discharge. While the reciprocating pump has less weight of pump for a given discharge. Centrifugal pumps are suitable for large discharge with a small head. Whereas reciprocating pumps are suitable for less discharge with a high head. Centrifugal pump requires more floor space and heavy foundation.

On Nov 14, 2013, an important discussion took place regarding the impact of closing the discharge valve in a centrifugal pump while it is running. This issue is critical not only for centrifugal pumps but also for positive displacement (PD) pumps. In this article, we will delve into the various problems that can arise when the discharge valve is closed during operation, as well as the consequences of closing the valve when starting the pump.

>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

Centrifugal Discharge Valve Closed

Centrifugal pumps rely on the principle of centrifugal force to move fluids through the system. When the discharge valve is closed while the pump is running, several issues can occur. One of the primary problems is the buildup of pressure within the pump and the associated increase in power consumption. The pump may struggle to maintain its flow rate, leading to inefficiencies and potential damage to the pump components.

Pump Discharge Valve Closed

In general, closing the discharge valve of a pump restricts the flow of fluid, causing back pressure to build up within the system. For centrifugal pumps, this can result in cavitation, a phenomenon where vapor bubbles form due to low pressure regions in the pump. Cavitation can lead to erosion of the pump impeller and other components, reducing the pump's efficiency and lifespan.

Discharge Valve Closed When Starting Pump

Closing the discharge valve when starting a pump can also have detrimental effects. When the pump is started with the discharge valve closed, the pump may experience a sudden surge in pressure, causing stress on the pump components. This can lead to mechanical failures, including seal damage and bearing wear. Additionally, the motor driving the pump may draw excessive current, leading to overheating and potential burnout.

Please explain what are all the problems that pump will encounter if the discharge valve is closed in the running condition for both centrifugal and PD pumps. In case of …
