How do I increase my head on my pump?

Throttle the valve by reducing the flow thus increasing the head. Reducing the flow also helps to reduce the frictional losses along the discharge line, so it will see an increase in pressure. Reducing the discharge pipe size will have adverse effect as it will increase the frictional losses across a smaller pipe.

What would be a graphical presentation of the pump head that is required to move fluid through a piping system at various flow rate?

A system curve, as shown in Figure 2, is a graphical representation of the pump head that is required to move fluid through a piping system at various flow rates. The system curve helps quantify the resistance in a system due to friction and elevation change over the range of flows.

What is the maximum head for a water pump?

Max Head refers to a pump’s capability to push water upwards (also known as ‘vertical lift’). So for example, a pump which states ‘Max Head: 7m’ means the pump will be able to push water flow up to 7 metres high from the water surface.

How do you calculate pump head from pipe length?

1. IMPORTANT NOTES :
2. TOTAL HEAD CALCULATION:
3. Total Head = suction Head + Delivery Head. Suction Head calculation = Suction vertical Height ( From Foot valve to Pump Centre) + Horizontal pipe line used + No of Bend (or) Elbow used in suction pipe line.
4. Example :-
5. Actul. Runnin.
6. Actul Total Head. —-
7. Head Conversion. Feet.

How is pump suction head calculated?

NPSH (A) = (Pressure on the liquid surface) (ha) ± (suction head/lift) (friction loss) (vapour pressure) (hvp) NPSH (A) = 9.02 + 4-1.2 – 0.25 = 11.57 Mts.

Which pump parameter will affect the head and efficiency of the pump?

Efficiency is the parameter affected most severely by viscosity, followed by capacity, then head. Since efficiency has the greatest effect, power cost should be evaluated as it may impact the pump selection.

What is system curve and pump curve?

A second curve, called the system curve, is used in conjunction with the pump curve and can be overlaid on the same graph. The system curve represents the system head in your specific application at various flow rates and is calculated by determining the system’s static head and friction loss.

What is system curve of centrifugal pump?

The system curve describes the increase in head resulting from increasing fluid flow through the pipework and other equipment in your plant. The pump curve describes the relationship between the rate of fluid flow and head for the pump itself.

What is the flow of a pump with multiple branches?

When a pump supplies multiple branches simultaneously, its flow will be the sum of the branch flows. If all the branches are at the same elevation, the pump head will be that elevation plus the sum of the friction heads between the pump and the branch outfalls.

How do you calculate the pump head of a hydropower system?

If all the branches are at the same elevation, the pump head will be that elevation plus the sum of the friction heads between the pump and the branch outfalls. If, however, the branches are at different elevations, the head required will be the sum of the friction heads and the elevation head of the highest branch.

What happens to the pressure when the pump head is lowered?

In this situation the pump will deliver its maximum pressure. If the pipe end is lowered as in Figure 10, the pump flow will increase and the head (also known as total head) will decrease to a value that corresponds to the flow.

What is the difference between head and energy in a pump?

Energy and head in pump systems. Energy and head are two terms that are often used in pump systems. We use energy to describe the movement of liquids in pump systems because it is easier than any other method. There are four forms of energy in pump systems: pressure, elevation, friction and velocity.
