I didn’t understand why that was so, and indeed if that is always the case in real life. Turns out that centrifugal pumps are always backward curved when used to pump water. The reasoning behind this fact follows.

Centrifugal pumps are widely used in various industries for transporting fluids. One of the crucial aspects of selecting a centrifugal pump is calculating the total head to ensure efficient operation. In this article, we will discuss the head calculation of a centrifugal pump, including determining the total head, NPSH available, specific speed, and predicting pump efficiency.

Learn safe assumptions when calculating the total head of a pump and how to deal with an oversized or undersized pump. As an engineer, there are times when calculations need to be done quickly, even when all of the desired

Centrifugal Pump Head Calculation Formula

The total head of a centrifugal pump can be calculated using the following formula:

\[ Total Head (H) = H_s + H_f + H_d \]

Where:

- \( H_s \) = Static Head

- \( H_f \) = Friction Head

- \( H_d \) = Elevation Head

Static Head is the vertical distance between the pump centerline and the highest point of the system where the liquid is discharged. Friction Head accounts for the energy loss due to friction in the piping system. Elevation Head is the difference in height between the pump centerline and the highest point of liquid in the system.

Calculate Head in Pump Diagram

To calculate the head in a pump diagram, you need to consider the pump curve provided by the manufacturer. The pump curve shows the relationship between the total head and the flow rate. By identifying the operating point on the pump curve, you can determine the total head required for the specific application.

NPSH Available and NPSH Required

NPSH (Net Positive Suction Head) is a critical parameter in centrifugal pump operation. NPSH Available is the amount of suction head available at the pump suction to prevent cavitation. It is essential to calculate the NPSH Available and compare it with the NPSH Required by the pump to ensure proper performance and avoid cavitation issues.

Centrifugal Pump Selection Calculator

Using a centrifugal pump selection calculator can simplify the process of choosing the right pump for your application. These calculators take into account factors such as flow rate, total head, NPSH requirements, and specific speed to recommend suitable pump models from various manufacturers.

Pump Sizing Calculator Online

Online pump sizing calculators are valuable tools for engineers and designers to quickly determine the pump size and specifications based on the system requirements. By inputting the necessary parameters such as flow rate, head, and fluid properties, these calculators provide recommendations for pump selection.

Specific Speed and Pump Efficiency Prediction

Calculate the head of a centrifugal pump pumping water at 20°C with a flow rate of 10L/s. The vacuum gauge at the inlet reads 0.031Mpa, and the pressure gauge at the outlet reads 0.126Mpa (gauge pressure).
