maximum head for centrifugal pump|pump head rating : purchaser The maximum "shut-off" head for a centrifugal pump can be estimated as. hs = (d n / 1840)2 (1) where. h = head (feet) d = outside diameter impeller (inches) n = wheel velocity - revolution … An axial-flow pump, or AFP, is a common type of pump that essentially consists of a propeller (an axial impeller) in a pipe. The propeller can be driven directly by a sealed motor in the pipe or by electric motor or petrol/diesel engines mounted to the pipe from the outside or by a right-angle drive shaft that pierces the pipe.

Dayton close-coupled units pump continuously, producing high flow rates under low-head conditions.
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:
JGGC4 water pump is a vertical multistage centrifugal pump with inlet and outlet flange are DN32. with flow rate Q: 1.5~7.0 m³/h @ 50Hz, 2900r/min and Max. head 211m. It is designed to transfer fresh water, widely used for boiler feed water, fire fighting and drinking water service, aslo can used for seawater RO system with SUS2205 material.A split-case centrifugal pump uses a casing that is split longitudinally along a vertical plane running through the center. This allows for quick and easy access for maintenance, operation and inspection of the internal components.
