Are your know the Significance of Nominal Diameter in GE Circulator Pumps
What is GE Circulator pumps？
GE Circulator pumps are an essential component of heating and cooling systems, providing the necessary water flow to ensure proper operation. The nominal diameter (DN) of GE circulator pumps is an important specification to consider when selecting the appropriate pump for your system.

What is GE Circulator pumps DN?
GE Circulator pumps DN refers to the nominal diameter of the pump, which is the internal diameter of the pipe that the pump is designed to fit into. This is important because the diameter of the pipe affects the flow rate and pressure of the water that the pump can circulate. In general, the larger the diameter of the pipe, the greater the flow rate and pressure that the pump can handle.
Common GE Circulator pumps DN sizes for circulator pumps include DN15, DN20, DN25, DN32, DN40, DN50, and DN65. The specific size you choose will depend on the size of your piping system and the flow rate and pressure requirements of your application.
For example, DN15 GE Circulator pumps have a nominal diameter of 15 millimeters and can handle a maximum flow rate of around 1.4 cubic meters per hour. These pumps are typically used in smaller piping systems. On the other hand, DN65 GE Circulator pumps have a nominal diameter of 65 millimeters and can handle a maximum flow rate of around 25 cubic meters per hour. These GE Circulator pumps are typically used in larger, commercial or industrial piping systems.

It is important to note that when connecting different DN sizes, appropriate fittings and seals must be used to ensure a stable and leak-free connection. Choosing the right DN size for your system can help ensure efficient and reliable operation of your circulator pump.
The following are common GE Circulator pumps DN specifications and their characteristics:
DN15: nominal diameter is 15 mm, pipe inner diameter is approximately 13.5 mm, maximum flow rate is approximately 1.4 m³/h, suitable for small pipe systems.
DN20: nominal diameter is 20 mm, pipe inner diameter is approximately 18 mm, maximum flow rate is approximately 2.5 m³/h, suitable for general pipe systems.
DN25: nominal diameter is 25 mm, pipe inner diameter is approximately 22.5 mm, maximum flow rate is approximately 4 m³/h, suitable for general pipe systems.
DN32: nominal diameter is 32 mm, pipe inner diameter is approximately 28.5 mm, maximum flow rate is approximately 6.3 m³/h, suitable for large pipe systems.
DN40: nominal diameter is 40 mm, pipe inner diameter is approximately 36.5 mm, maximum flow rate is approximately 10 m³/h, suitable for large pipe systems.
DN50: nominal diameter is 50 mm, pipe inner diameter is approximately 45.5 mm, maximum flow rate is approximately 16 m³/h, suitable for large pipe systems.
DN65: nominal diameter is 65 mm, pipe inner diameter is approximately 62.5 mm, maximum flow rate is approximately 25 m³/h, suitable for extra-large pipe systems.
Here is a conversion chart for DN sizes to inches:
DN15 = 1/2 inches
DN20 = 3/4 inches
DN25 = 1 inch
DN32 = 1 1/4 inches
DN40 = 1 1/2 inches
DN50 = 2 inches
DN65 = 2 1/2 inches
