Search by pump type and family or by capacity and head. Further refine the pump curves to find the pump that meets your specification. 



Dimensional drawings

To assist you in the planning stages of new installations or the modification of existing ones, Johnson Pump offers you dimensional drawings and simplified 3D models of our pumps.

These dimensional drawings in AutoCAD® .DWG (R13) format and 3D models in .IGES format will allow you to precisely fit our pumps into your piping system.

The downloadable dimensional files are arranged according to pump family, and further according to the pump size diameter of the discharge connection (mm).

Inside each self-extracting ZIP archive you will find all the dimensional files for the different possibilities for that particular pump size; including nominal impeller diameter (mm) and IEC electric motor combinations.
