centrifugal pump calculations|centrifugal pump size chart : OEM Dec 18, 2024 · In this in-depth guide, we’ll cover everything you need to know about centrifugal pumps, including their types, features, design considerations, and even an easy-to-use pump … A decanter centrifuge, also known as a horizontal bowl centrifuge, solid bowl centrifuge or scroll centrifuge, is a machine used to separate a solid material from a liquid(s) using a high-speed and continual rotational process. Due to centrifugal force, the heavier particles are pushed through the liquid and collected on the inner wall of the bowl; the high-speed rotation of the bowl separates .

Decanter centrifuges with the same diameter but the longer length would have a higher capacity for conveying solids and attain a larger suspension volume, which would enhance the settling out of fine solids. [10] The beach angle at the conical section of a decanter centrifuge is a design heuristic, which must also be taken into consideration .
Centrifugal pumps are widely used in various industries for fluid transportation. Proper calculations are essential to determine the performance characteristics of a centrifugal pump. In this article, we will discuss how to calculate the pump performance curve values for volume flow rate, RPM, head pressure, pump power, and impeller diameter for a centrifugal pump.

Centrifugal Pump Calculations Overview
When it comes to centrifugal pump calculations, several key parameters need to be considered to ensure efficient pump operation. These parameters include volume flow rate, RPM (revolutions per minute), head pressure, pump power, and impeller diameter. By accurately calculating these values, engineers and operators can determine the pump's performance capabilities and optimize its efficiency.
Volume Flow Rate Calculation
The volume flow rate of a centrifugal pump is the amount of fluid that the pump can deliver per unit of time. It is typically measured in cubic meters per hour (m³/h) or gallons per minute (GPM). The formula to calculate the volume flow rate is:
\[Q = \frac{Q_{design} \times RPM}{RPM_{design}}\]
Where:
- \(Q\) = Volume flow rate at the operating RPM
- \(Q_{design}\) = Volume flow rate at the design RPM
- \(RPM\) = Operating RPM of the pump
- \(RPM_{design}\) = Design RPM of the pump
Head Pressure Calculation
Head pressure, also known as total dynamic head (TDH), is the pressure that the pump must overcome to move the fluid from the suction side to the discharge side. It is a crucial parameter in determining the pump's performance. The formula to calculate head pressure is:
\[H = \frac{P}{\rho \times g}\]
Where:
- \(H\) = Head pressure
- \(P\) = Pressure difference between suction and discharge sides
- \(\rho\) = Density of the fluid
- \(g\) = Acceleration due to gravity
Pump Power Calculation
The pump power is the amount of power required to operate the centrifugal pump and is typically measured in horsepower (HP) or kilowatts (kW). The formula to calculate pump power is:
\[P = \frac{Q \times H \times \eta}{3.65 \times 10^6}\]
Where:
- \(P\) = Pump power
- \(Q\) = Volume flow rate
- \(H\) = Head pressure
- \(\eta\) = Pump efficiency
Impeller Diameter Calculation
The impeller diameter of a centrifugal pump plays a significant role in determining the pump's performance characteristics. The impeller diameter affects the pump's flow rate, head pressure, and efficiency. The formula to calculate the impeller diameter is:
\[D = \sqrt[3]{\frac{Q}{\pi \times N}}\]
Where:
- \(D\) = Impeller diameter
- \(Q\) = Volume flow rate
- \(N\) = Pump speed in revolutions per minute (RPM)
Conclusion
Centrifugal pumps are one of the most common components inserted in fluid systems. In order to understand how a fluid system containing process piping and accessories operate, it is …
Decanter centrifuges are characterized by their continuous operation, the presence of a scroll (a helical screw that rotates at a slightly slower speed than the bowl and conveys the solids towards the outer wall of the bowl), and a solids discharge port located on the outer wall of the bowl. They are used in a wide range of industries and .
