The single stage centrifugal pump mentioned here contain the end suction pump, close-coupled pump, inline pump. All of those pump's impeller overhungs on one end of the shaft, so they belongs to the group of overhung pumps.

The end suction pump is the most common centrifugal pump used in projects. We have IES end suction pump, NO end suction pump and NE end suction pump. Each type end suction has its own application. IES end suction pump is for general application. NO end suction pump has open or semi-open impeller are used for liquid with solids or high viscosity. NE end suction pump has inducer impeller to meet the application with low NPSH.

Another big group of pumps are close-coupled pumps. IEC close-coupled pump are derivated from IES end suction pump and have the save peformance with IES. ES colse-coupled pump are the different type of close-coupled pump usually used of 50Hz electricity.

The third group of the veritcal single stage pump are inline pump, we have IEV inline pump and ESV inline pump. IEV inline pump are also derivated from IES end suction pump and have the same performance with IEC close-coupled pump. ESV inline pump has the same performance with ES close-coupled pump.

So we suggested, if you need overhung pump, please consider firstly IES for end suction pump or IEC for close coupled pump and IEV for inline pump. because IE family pump can be used both for 50Hz and 60Hz electricity.

IEC type is the single stage, close-coupled pump, which meets the standard DIN24255 and ISO2858 to ensure the dimensional interchangeability with other pumps. The IEC type close-coupled pump and the motor is coupled together through the sleeve or coupling clutch. The pump and motor can also share the same shaft. So IEC type close-coupled pump is not neccessary to verify the coaxial state and easy to maintenance. The pump and the motor is fixed direclty together through coupling bracket, then the comlete set installed on the common baseframe.

Main designing features
