manometric head in centrifugal pump|sectional view of centrifugal pump : importer
In a centrifugal pump, ‘classic’ cavitation occurs at the eye of the impeller as it imparts velocity on the liquid (see Figure 1). In a positive displacement pump, it can happen in an expanding piston, plunger or suction-side chamber in a gear .

Sectional View of Centrifugal Pump
A centrifugal pump consists of various components, including the impeller, casing, and shaft. The impeller is responsible for creating the flow within the pump, while the casing directs the flow towards the outlet. The shaft connects the motor to the impeller, allowing for the transfer of mechanical energy to the fluid.
How to Calculate Pump Head
Pump head is a crucial parameter in determining the performance of a centrifugal pump. It represents the energy imparted to the fluid by the pump and is essential for calculating the pressure at the pump outlet. The pump head can be calculated using the following formula:
\[ \text{Pump Head (H)} = \frac{P}{\rho g} + \frac{V^2}{2g} + Z \]
Where:
- \( P \) = Pressure head
- \( \rho \) = Density of the fluid
- \( g \) = Acceleration due to gravity
- \( V \) = Velocity of the fluid
- \( Z \) = Elevation head
Manometric Efficiency of Centrifugal Pump
The manometric efficiency of a centrifugal pump is a measure of how effectively the pump converts mechanical energy into pressure energy. It is defined as the ratio of the manometric head to the theoretical head. A high manometric efficiency indicates that the pump is operating efficiently and effectively.
Centrifugal Pump Head Efficiency
The head efficiency of a centrifugal pump is a measure of how well the pump is able to convert the energy input into pressure energy. It is calculated by dividing the actual head by the theoretical head and is expressed as a percentage. A high head efficiency indicates that the pump is operating at peak performance.
Centrifugal Pump Impeller Dimensions
The dimensions of the impeller in a centrifugal pump play a crucial role in determining the pump's performance. The diameter, width, and number of blades on the impeller all impact the flow rate, head, and efficiency of the pump. Properly sized impeller dimensions are essential for optimizing the pump's performance.
Delivery Head of Centrifugal Pump
The delivery head of a centrifugal pump is the total head developed by the pump at its outlet. It includes the static head, velocity head, and pressure head. The delivery head is a critical parameter in determining the pump's ability to overcome resistance in the system and deliver fluid at the required pressure.
Velocity Triangle of Centrifugal Pump
The velocity triangle of a centrifugal pump illustrates the relationship between the fluid velocity at the inlet and outlet of the impeller, as well as the blade velocity. By analyzing the velocity triangle, engineers can optimize the design of the impeller to maximize efficiency and performance.

The performance characteristics of a certain centrifugal pump are determined from an experimental setup similar to that shown in the figure below. When the flowrate of a liquid (SG = 0.9) through the pump is 124 gpm, the pressure gage at (1) indicates a vacuum of 98 mm of mercury and the pressure gage at (2) indicates a pressure of 78 kPa.
