Frequently Asked Questions

If you have a Close Coupled pump, you can find the base your looking for here.

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.


View ANSI/ASME Sizing Reference Chart.


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. 3×2-11) 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.


As mentioned in the above section (How do I know what size base I need?), the BaseTek pre-engineered baseplates have been designed to accommodate standard ANSI pumps and NEMA frame motors.   Just as many pump manufacturers comply with the ANSI B73.1M standard, so do various motor manufacturers comply with certain dimensional criteria know as NEMA standards.   By checking the nameplate of your motor, if your motor is a NEMA motor, you will find a designated NEMA frame listing (for example, 143T, 145T, and so on up to a 405T frame for our pre-engineered baseplates.  These NEMA frame dimensions apply to all TEFC (Totally Enclosed Fan Cooled) and Open Drip Proof motors and designated by the “T” following the respective number.


Please note that if your motor is a C-Flange style motor then there is no need to concern yourself with motor mounting holes on smaller motors that are typically 213TC or less (please verify and follow pump manufacturers recommendations).   The motor will be supported by the pump flange and suspend freely off the back end of the pump.   For C-Flange motors that require foot mounting, we can provide a custom base drilling pattern in our Custom QuickBase™.  We also offer insert kits which allow for shop or field installation of mounting inserts (please see our accessory page).  Mounting blocks are also available.  For assistance in determining the necessary motor blocks, please proceed to our PoxyBlock™ section in this web site or consult with BaseTek for guidance.


We strongly recommend against the use of threaded studs for mounting the feet of C-Flange motors as to facilitate proper back-pullout.


Be careful – most major motor manufacturers violate the NEMA dimension of a motor when they convert a standard “T” frame motor to a “C” frame.


Still haven’t found a NEMA frame size?   Then you may have a special motor that needs to be customized to our family of baseplates.  NO PROBLEM!  Please proceed to our custom QuickBase™ section.


As mentioned previously, the pre-engineered BaseTek baseplates have been designed to accommodate ANSI dimensional pumps and NEMA “T” frame motors. For the identified pumps and motors that our pre-engineered baseplates have been designed for, the industry standard is to account for a spacer coupling width of 3.5”. The 3.5” allows the end user adequate space to properly assemble and disassemble the spacer coupling should the need arise to perform maintenance on either the pump or motor.
