what is head in centrifugal pump|centrifugal pump head calculation : commercial
When a screw pump pumps oil or other types of viscous fluids, the screw surfaces are lubricated as the fluid is pumped, so there is little or no clearance between the screws. However, when pumping gas/water mixtures, water, or other types of light liquids, these components cannot come into contact with each other.

When it comes to selecting a centrifugal pump, one of the key parameters to consider is the head. Understanding what head is and how it relates to the performance of a centrifugal pump is crucial in ensuring the pump operates efficiently and effectively. In this article, we will delve into the concept of head in centrifugal pumps, the steps to follow to select the right pump, and various other aspects related to centrifugal pump head calculation.
Head is the height at which a pump can raise water up, that's it, it's that simple. Figure 2 The meaning of head. Connect a tube to the discharge of a pump and measure the water height, that the head of the pump. OK, so head is somehow linked to pressure, in what way? We will get to
Characteristics of Centrifugal Pump
Centrifugal pumps are widely used in various industries for their ability to efficiently move fluids. One of the essential characteristics of a centrifugal pump is its ability to generate head. Head in a centrifugal pump refers to the height to which the pump can raise a fluid. It is essentially the energy imparted to the fluid by the pump, which results in the fluid being pushed to a certain height or pressure.
Pentair High Head Centrifugal Pump
Pentair is a well-known manufacturer of high-quality centrifugal pumps, including high head centrifugal pumps. These pumps are specifically designed to handle applications that require pumping fluids to higher elevations or pressures. The Pentair high head centrifugal pump is engineered to deliver superior performance and reliability in demanding environments.
Performance Characteristics of Centrifugal Pump
The performance of a centrifugal pump is influenced by various factors, including the pump's head, flow rate, efficiency, and power consumption. Understanding the performance characteristics of a centrifugal pump is essential in selecting the right pump for a specific application. The performance curve of a centrifugal pump provides valuable information about how the pump will operate under different conditions.
High Head Centrifugal Pumps
High head centrifugal pumps are designed to generate higher pressures or lift fluids to greater heights compared to standard centrifugal pumps. These pumps are commonly used in applications such as water supply, irrigation, and high-pressure cleaning systems. High head centrifugal pumps are capable of delivering the required pressure to overcome friction losses and elevation changes in the system.
Characteristic Curves of Centrifugal Pump
Characteristic curves of a centrifugal pump provide a graphical representation of the pump's performance under varying operating conditions. The two main characteristic curves of a centrifugal pump are the head-capacity curve and the efficiency curve. These curves help in understanding how the pump will behave at different flow rates and pressures, enabling engineers to select the most suitable pump for a specific application.
Positive Suction Head Centrifugal Pump
Positive suction head (PSH) is an important consideration in centrifugal pump applications, especially when dealing with low-pressure or vacuum conditions at the pump inlet. A centrifugal pump requires a certain level of positive suction head to prevent cavitation, which can damage the pump and reduce its efficiency. Properly calculating the positive suction head ensures the pump operates smoothly and efficiently.
Typical Centrifugal Pump Efficiency
Centrifugal pump efficiency is a measure of how effectively the pump converts input power into hydraulic energy. The efficiency of a centrifugal pump is influenced by factors such as the design of the pump, operating conditions, and maintenance practices. Typical centrifugal pump efficiencies range from 50% to 90%, with modern high-efficiency pumps capable of achieving even higher efficiency levels.
