KIESEL pumps are suitable for a huge range of applications. The pumps have proved one’s worth since 1965. They can solve any task to pump nearly all mediums continuously, softly, less of vibration and with equalized pressure. KIESEL pumps can be used in almost every industrial sector. Eccentric screw pumps are self-priming displacement pumps.
Centrifugal pump specific speed is a crucial parameter used in the evaluation and selection of centrifugal pumps. It is a dimensionless number that provides valuable information about the performance characteristics of a pump. Specific speed is defined as the speed at which a geometrically similar pump would operate to deliver 1 unit of flow rate against 1 unit of head. Understanding the specific speed of a centrifugal pump is essential for engineers and designers in optimizing pump performance and efficiency.
The calculator below can used to calculate the specific speed: Note!When comparing pumps and their documentation - be aware of the units used. Typical values for specific speed - Ns - for different designs in US units(US gpm, ft) 1. radial flow pump design - 500 < Ns < 4000- typical for centrifugal impeller pumps
Pump Specific Speed Chart
Specific speed is calculated using the formula:
\[ N_s = \dfrac{N \sqrt{Q}}{H^{3/4}} \]
Where:
- \( N_s \) = Specific speed
- \( N \) = Pump speed (rpm)
- \( Q \) = Flow rate (m\(^3\)/s)
- \( H \) = Total head (m)
Specific speed values can vary widely depending on the pump design and application. For centrifugal pumps, specific speed is typically categorized into three ranges:
1. Low Specific Speed (N_s < 500)
2. Medium Specific Speed (500 < N_s < 2500)
3. High Specific Speed (N_s > 2500)
Centrifugal Pump Efficiency Chart
Efficiency is a critical factor in the performance of centrifugal pumps. The efficiency of a pump is influenced by its specific speed, design, and operating conditions. A centrifugal pump efficiency chart provides a graphical representation of the relationship between flow rate, head, and efficiency for a specific pump.
Specific Speed of Pump Calculator
To calculate the specific speed of a centrifugal pump, you can use online calculators or software tools specifically designed for this purpose. These calculators require input parameters such as pump speed, flow rate, and total head to determine the specific speed of the pump.
How to Calculate Pump Speed
The speed of a pump is typically specified by the manufacturer and is an essential parameter for pump selection and operation. Pump speed can be calculated using the formula:
\[ N = \dfrac{120 \times f}{P} \]
Where:
- \( N \) = Pump speed (rpm)
- \( f \) = Frequency of power supply (Hz)
- \( P \) = Number of poles in the motor
Suction Specific Speed Calculator
Suction specific speed is another important parameter used in the evaluation of centrifugal pumps, especially for applications with high suction energy. The suction specific speed calculator helps determine the suction specific speed of a pump based on input parameters such as flow rate, suction head, and impeller diameter.
Specific Speed of Pump Definition
A pump has the capacity 1500 US gal/min (1249 British gpm, 340 m3/h, 5667 liters/min) at 100 ft(30.5 m) of head and is rotating at 1760 rev/min. See more
The purpose of the mechanical seal is to control leakage from the stuffing box or seal chamber and prevent air from leaking back into the pump. Mechanical seals are typically divided into .
