BaseTek has currently pre-engineered 9 different baseplate sizes to accommodate various ANSI/ASME B73.1M pump sizes and NEMA frame motor sizes. The ANSI/ASME B73.1M standard was established so that various manufacturers could abide by an industry standard so as to have common dimensional standards and interchangeability of various size pumps within a given envelope. The ANSIASME B73.1M specification has a dimensional designation of AA to A120 that covers 19 various size pumps. These dimensional standards cover not only the pump itself, but also covers the spaced dimensions of the pump feet, respectively.

Have you found your pump from the sizing chart? If so, you can see the dimensions required by the pump’s footprint and match it with one of our drawings listed (Drawings can be viewed and printed in under the “Documents” section of this site). Drawings BT127, BT139, BT148 and BT153 accommodate ANSIASME pump dimensions AA and AB with various NEMA frame motors (ranging from NEMA 143T to NEMA 326T frames) as listed in the bottom right hand corner of the respective BaseTek drawings. Drawings BT245, BT252, BT258, BT264 and BT268 accommodate ANSI pump dimensions A10, A50, A60, A70, A05, A80, A20, A30 and A40 with various NEMA frame motors (ranging from NEMA 143T to NEMA 405T frames) as listed in the bottom right hand corner of the respective BaseTek drawings.
Please note that some pump manufacturers take the liberty of providing larger nominal impeller sizes (i.e. 3x2-11) yet still comply with a given ANSI designation. Again, the key is to confirm the ANSI designation with the manufacturer or by reviewing a drawing or taking an actual measure of the feet themselves.
Still unable to locate your pump dimension or motor frame? Then you have a NON-ANSI pump or NON-NEMA frame motor. This tells you that you have a candidate for BaseTek’s exclusive QuickBase™ offering and should proceed to that section of this website or call us to assist you in selecting the appropriate baseplate for your given pump and motor. We are always glad to help guide you for proper baseplate selection.
