maximum head for centrifugal pump|pump head rating : manufacturer The total head at zero flow is the maximum head also called the shut-off head, the total head decreases as the flow increases. The plot of total head vs. flow for a centrifugal pump is very typical and it looks like this: Screw Pump Design. There are typically three design types: Single Screw. This is usually another name for a progressing cavity pump where a single screw rotated by a motor rotates within a stator. This is covered in our progressing cavity pump guide.

A dry screw vacuum pump consists of two parallel, non-contacting helical screw-shaped rotors (1) and (2), Fig. 1, rotating synchronously at high speeds via precision gears (3).They rotate in opposite directions, and in so doing, trap a quantity of gas at the inlet (5) and transport it towards the exhaust port (6) and into the exhaust channel (7). .
Centrifugal pumps play a crucial role in various industries, including oil and gas, water treatment, and manufacturing. One essential parameter to consider when selecting a centrifugal pump is the maximum head it can achieve. The maximum head of a centrifugal pump refers to the height to which the pump can raise a fluid. At the maximum head, the pump operates at zero flow or minimal flow rate, a condition often known as the shut-off head.
At the maximum head (circled in red), the pump has zero flow or little. This is often referred to as the shut-off head. When looking for a pump, ensure that the head provides a sufficient flow rate.
Centrifugal Pump Head Size
The head size of a centrifugal pump is a critical factor that determines its performance capabilities. It is essential to understand the maximum head that a pump can generate to ensure it meets the specific requirements of the application. The head size of a centrifugal pump is typically specified by the manufacturer and is an important parameter to consider during the selection process.
Centrifugal Pump Head
The head of a centrifugal pump is the energy per unit weight of fluid imparted to the liquid by the pump. It represents the pressure or height to which the pump can raise the fluid. The maximum head of a centrifugal pump is a crucial parameter that influences the pump's ability to overcome resistance in the system and deliver the required flow rate.
Pump Head Specification
When evaluating centrifugal pumps, it is essential to review the pump head specifications provided by the manufacturer. The pump head specification includes information about the maximum head, shut-off head, and other performance parameters of the pump. Understanding these specifications is vital to ensure the pump can meet the requirements of the application.
Centrifugal Pump Shut-Off Head
The shut-off head of a centrifugal pump refers to the maximum head at which the pump operates at zero flow. This condition occurs when the pump is working against a fully closed valve or a system with high resistance. The shut-off head is an important parameter to consider as it indicates the maximum pressure that the pump can generate under no-flow conditions.
Total Head Pump Parameters
Total head is a comprehensive parameter that includes the static head, friction head, and velocity head of the system. It represents the total energy required by the pump to overcome all resistance and elevate the fluid to the desired height. Understanding the total head pump parameters is essential for selecting the right centrifugal pump for a specific application.
Centrifugal Pump Power Calculation
The power required to operate a centrifugal pump is directly related to the pump head and flow rate. The power calculation for a centrifugal pump involves considering the pump's efficiency, head, and flow rate to determine the amount of power needed to meet the system requirements. Proper power calculation is crucial for ensuring the pump operates efficiently and effectively.
Pump Head Rating
The pump head rating is a key performance indicator that indicates the maximum head a centrifugal pump can achieve under specific operating conditions. It is essential to review the pump head rating provided by the manufacturer to ensure the pump can meet the required performance criteria. The pump head rating is crucial for determining the pump's suitability for a particular application.
Pump Head and Total Head
The total head at zero flow is the maximum head also called the shut-off head, the total head decreases as the flow increases. The plot of total head vs. flow for a centrifugal pump is very typical and it looks like this:
