Calculation of electric pump water flow
Calculation of the flow rate of circulation pumps in hot and cold water systems
Welcome to the "Electropump Water Flow Calculation" program dedicated to heating and refrigeration. In a world where thermal comfort is essential for residential, commercial and industrial environments, the accurate management of the water flow and the efficiency of the electric pumps play a fundamental role in guaranteeing the optimal functioning of the heating and refrigeration systems.
This program was created by Itieffe specifically for those working in the heating, air conditioning and refrigeration sector. The goal is to provide a practical and effective tool for calculating the water flow required for the type of system under consideration.
Through a series of intuitive steps, you will be able to enter the key parameters: the potential of the system and the Delta T (Δt). The program will immediately return the data relating to the water flow necessary to ensure that the carrier fluid is able to transmit the energy required by the system.
Whether you're a heating engineer, HVAC technician or an HVAC enthusiast, this program has been designed to fit your needs and speed up your work.
Without further ado, let's immerse ourselves in the use of the "Electropump Water Flow Calculation" program and find out how this tool can facilitate the design of a system.
Calculation of electric pump water flow
How to quickly calculate the flow rate of circulation pumps in hot and cold water systems.
Just enter the plant potential by choosing from the various options offered by the drop-down menu, choose the delta t (Δt) in degrees centigrade or Fahrenheit and indicate in which unit of measurement you want the result of the water flow rate of the electric pump.
Results in m³ / h, liters / h, liters / min and liters / sec and Anglo-Saxon units of measure.
To complete the program, the "Average yields of the electric pumps and circulators" and the "Characteristic curves of the electric pumps in series and in parallel" are entered.

| Average efficiency of mechanical seal electric pumps | |
| Power supplied by the pump kW | Average yield% |
| <1,5 | 30 ÷ 65 |
| 1.5 ÷ 7,5 | 35 ÷ 75 |
| 7,5 ÷ 45 | 40 ÷ 75 |
| Average circulator efficiency | |
| Power supplied to the circulator W | Average yield% |
| <100 | 10 ÷ 25 |
| 100 ÷ 500 | 20 ÷ 40 |
| 500 ÷ 2.500 | 30 ÷ 50 |
