Centrifugal pump is a hydraulic machine which converts mechanical energy into hydraulic energy by the use of centrifugal force acting on the fluid. These are the most popular and widely used type of pumps for transferring fluids in various industries. In this article, we will discuss the importance of the delivery valve in starting a centrifugal pump, how it works, its parts, and other related aspects.

When starting a centrifugal pump, it is generally recommended to keep the delivery valve fully closed. This is done to prevent excessive pressure build-up in the pump and to protect the

What is a Centrifugal Pump?

A centrifugal pump is a type of dynamic pump that uses a rotating impeller to increase the pressure and flow rate of a fluid. The impeller rotates at high speeds, creating a centrifugal force that pushes the fluid towards the outer edges of the pump casing. As the fluid moves through the pump, it gains kinetic energy and exits through the discharge outlet.

Centrifugal Pump Delivery Valve Closed

Before starting a centrifugal pump, it is important to ensure that the delivery valve is closed. The delivery valve is a crucial component of the pump that controls the flow of fluid from the pump to the system it is connected to. By closing the delivery valve, the pump is able to build up pressure inside the casing, which is necessary for the pump to operate efficiently.

How Centrifugal Pump Works

When the centrifugal pump is started, the impeller begins to rotate, creating a low-pressure zone at the center of the pump casing. This low pressure causes the fluid to be drawn into the pump through the suction inlet. As the fluid moves through the impeller, it gains kinetic energy and is forced towards the outer edges of the casing.

The fluid then exits the pump through the discharge outlet, where it is directed to the system it is connected to. By controlling the speed of the impeller and the size of the pump casing, the flow rate and pressure of the fluid can be adjusted to meet the requirements of the system.

Centrifugal Pump Parts Diagram

A centrifugal pump consists of several key parts that work together to convert mechanical energy into hydraulic energy. These parts include:

1. Impeller: The rotating component of the pump that imparts energy to the fluid.

2. Casing: The outer shell of the pump that contains the impeller and guides the flow of fluid.

3. Suction Inlet: The opening through which fluid enters the pump.

4. Discharge Outlet: The opening through which fluid exits the pump.

5. Delivery Valve: Controls the flow of fluid from the pump to the system.

6. Shaft: Transmits power from the motor to the impeller.

7. Bearings: Support the shaft and allow it to rotate smoothly.

Foot Valve for Centrifugal Pump

In some applications, a foot valve is used in conjunction with a centrifugal pump to prevent backflow of fluid when the pump is not in operation. The foot valve is installed at the suction inlet of the pump and allows fluid to flow into the pump while preventing it from flowing back out. This helps maintain the prime of the pump and ensures that it is ready to start efficiently.

Centrifugal Pump Heads

The head of a centrifugal pump refers to the height to which the pump can lift a fluid. It is a measure of the pump's ability to overcome resistance in the system it is connected to. The head of a centrifugal pump is influenced by factors such as the speed of the impeller, the size of the pump casing, and the density of the fluid being pumped.

Pump Discharge Valve Closed

If you start the pump with discharge valve open, the discharge head will act on the pump ie, more resistance, so the motor has to give more starting torque to the pump which means more …

3. OPERATING PRINCIPLES Liquid enters the suction nozzle & later into the eye of the impeller due to the rotation of the pump impeller. Low pressure region “pulls” the liquid towards the eye of the impeller. The rotation of the impeller radially pushes the liquid → centrifugal acceleration. The centrifugal force & curved nature of the blade pushes the liquid in the tangential and radial .
