A centrifugal pump at the source tank sends fluid 200m

In summary, the conversation discusses the operation of a centrifugal pump and the effects of pressure on its performance. It is revealed that the pump stops when the automatic valve on the recieval tank shuts, due to a pressure sensor. The pump is capable of sending fluid 200m using 3" hoses and has a flow rate of 30000L/H. The conversation also includes questions about the pressure at the pump and valve ends, as well as the impact of bends and pipe heights on pressure.

Hi,

This is a question regarding my employment.

A centrifugal pump at the source tank sends fluid 200m using 3" hoses to a recieval tank.
When the automatic valve shuts on the recieval tank the pump stops due to it having a pressure sensor.When the pump stops there is 8 Bar pressure on the sensor reading.The pump does 30000L/H

1. If there is 8 Bar pressure at the pump when it has stopped would the pressure also be 8 Bar at the valve end which is 200m away?
2. When the valve shuts does it send pressure all the way back to the pump?
3. Do bends and varying heights in pipes cause pressure?

Thank you

Tony

2. yes
3. sharp bends cause pressure loss in liquid
 

1. How does a centrifugal pump work?

A centrifugal pump uses rotational energy to create a flow of fluid. The pump has an impeller that rotates, creating a low-pressure area at the center which draws in fluid. The fluid is then pushed outward by the rotation of the impeller, increasing its velocity and creating a high-pressure area that sends the fluid out of the pump.

2. What is the purpose of using a centrifugal pump at the source tank?

The centrifugal pump is used to move fluid from one location to another with a high flow rate and low pressure. In this case, it is used at the source tank to push the fluid through a 200m distance to its destination.

3. How much fluid can a centrifugal pump move?

The amount of fluid a centrifugal pump can move depends on its size, speed, and efficiency. It is typically measured in gallons per minute (GPM) or liters per second (LPS). A larger pump with a higher speed and efficiency will be able to move more fluid than a smaller pump.

4. What type of fluid can be moved by a centrifugal pump?

A centrifugal pump can move a variety of fluids, including water, oil, chemicals, and slurries. The type of fluid being moved will determine the materials and design of the pump to ensure compatibility and efficient operation.

5. How is the distance a centrifugal pump can move fluid determined?

The distance a centrifugal pump can move fluid is determined by several factors, including the pump's head (pressure), flow rate, and the characteristics of the fluid being moved. The higher the head and flow rate, the further the pump can move the fluid. However, friction losses and other factors may also affect the pump's ability to move fluid over a distance.
